Equation of a line that has a slope of 4 and passes through point (1, 6) is y = 4x + 2 . Hence, C is the correct option.
What is equation of the line?To represent the standard form of equation of a line are:
Slope-intercept form:
y = mx + c
Here m represent the slope of the given line and c is the y intercept.
Intercept form:
x/a + y/b = 1
Generic way of representing the straight line, i.e. Ax+By+C = 0
x/(-C/A) + y/(-C/B) = 1
Hence a = -C / A and b = – C / B
Normal form:
The equation of the line whose length of the normal from the origin is p and the angle made by the normal with the positive x-axis is given by α is given by:
x cos α+y sin α = p
General equation of the line is represented in the form:-
y - y1 = m (x-x1) ,
Where x1, y1 represents a point on the line whereas,
m represents the slope of the line.
= (1 , 6) point on the line

use f(x)=|x|
f(x) is shifted down 4 and right 3 to create h(x)
which answer shows the correct function for h(x)
Answer:
h(x)= |x-3|-4
Step-by-step explanation:
If f(x) = |x| is shifted down 4 and right 3 to create h(x), then h(x) = |x - 3| - 4
The function is given
f(x) = |x|
Translation of the shape mean the displacement of the shape from one place to another place. Some usually used displacements are shifted to right / left and shifted to up / down etc.
First f(x) is shifted down 4
Then the function will become
f(x) = |x| - 4
Then the function shifted right 3
Then the function will be
h(x) = |x - 3| - 4
Hence, if f(x) = |x| is shifted down 4 and right 3 to create h(x), then h(x) = |x - 3| - 4

Traveling by sea was historically one of the most effective methods of globetrotting. Greeks in antiquity to medieval SpanishKings, because it provided the possibility of new business ventures and trade routes, exploration was a top priority for governments. Spanish ships, for instance, could travel to China and return with Chinese spices and silks (which were not accessible in continental Europe) to sell in Spanish marketplaces.In order to avoid deviating from their intended course, early explorers used a navigational system known as "dead reckoning," which involves calculating their position based on previous positions (such as landmasses).

Set F(x) to 0, and you get ax2 + bx + c = 3x2 -40x + 180.
[-b +/- (b2 -4ac)(1/2)] is the quadratic formula. / 2a.
The stuff under the square root / radical (b2 - 4ac) is the KEY to your answer, and it determines whether you have two real, one real, or two imaginary answers. The discriminant is the term (b2 - 4ac).
Obviously, if (b2 - 4ac) > 0, you have two real answers, because the square root of a positive number is also a (positive) real number. And -b multiplied by a real number (and divided by 2a) yields two (real) answers.
If (b2 - 4ac) = 0, you have one correct answer because the square root of 0 is zero. And -b multiplied by a 0 real number (and divided by 2a) yields 1 (real) answer.
(b2 - 4ac) 0 yields two fictitious answers, because the square root of a negative number is a fictitious number. And -b multiplied by an imaginary number (and divided by 2a) yields two (complex) answers.
In this case, (b2 - 4ac) = ((-40)2 - 4(3)(180)) = 1600 - 2160 0 As a result of the discriminant is negative, the quadratic formula yields two complex answers.

The cost of plastering the rectangle walls at rate of Rs.15/[tex]m^2[/tex] is Rs.5565.
What is rectangle?
With four sides, four corners, and four right angles (90°), a rectangle is a closed 2-D object. A rectangle's opposing sides are equal and parallel. Since a rectangle is a two-dimensional form, it has two dimensions: length and width. The opposite sides of a quadrilateral are equal and parallel, and all the angles are equal. Around us, there are several rectangle-shaped items. Two dimensions, the length and breadth, define each rectangle shape. The width and length of a rectangle are its longer and shorter sides, respectively.
Given,
Length of room =12m
Breadth of room =10m
Height of room =6m
So, Area of four walls =2(l+b)×h
=>area of four wall=2(12+10)×6=264[tex]m^2[/tex]
Now Area of 2 doors and 3 windows =(2×1×2+3×2×1.5)
=> area of 2 doors and 3 windows = 13[tex]m^2[/tex]
Area of ceiling =l×b=12×10=120 [tex]m^2[/tex]

A=P(1+r/100)^n express r in terms of A,P, and n
Answer:
[tex] \huge{ \boxed{r =100( \sqrt[n]{ \frac{A}{P} } - 1)}}[/tex]
Step-by-step explanation:
[tex]A = P(1 + \frac{r}{100} )^{n} \\ [/tex]
First of all in order to make r the subject we have to first divide both sides of the equation by P
That's
[tex] \frac{A}{P} = \frac{P( {1 + \frac{r}{100} })^{n} }{P} \\[/tex]
We'll finally get
[tex] \frac{A}{P} = ( {1 + \frac{r}{100}) }^{n} \\ [/tex]
Next we have to remove the power n and to do that we find the square root of 'n' of both sides as
We have
[tex] \sqrt[n]{ \frac{A}{P} } = \sqrt[n]{( {1 + \frac{r}{100} })^{n} } \\ \\ \\ \sqrt[n]{ \frac{A}{P} } = 1 + \frac{r}{100} [/tex]
Next we subtract 1 from both sides to isolate r/100
We have
[tex]\sqrt[n]{ \frac{A}{P} } - 1 = 1 - 1 + \frac{r}{100} \\ \sqrt[n]{ \frac{A}{P} } - 1 = \frac{r}{100} [/tex]
Finally to isolate r , we multiply both sides by 100
[tex] \frac{r}{100} \times 100 =100 \times (\sqrt[n]{ \frac{A}{P} } - 1)[/tex]
We have the final answer as
[tex]r =100( \sqrt[n]{ \frac{A}{P} } - 1) \\ [/tex]

Setup(x/5) +2 . . . . the value after dividing by 5 and adding 2
(x +22)/10 . . . . the value after adding 22, then dividing by 10
These two outcomes are the same:
x/5 +2 = (x +22)/10
SolutionMultiplying the equation by 10 gives ...
2x +20 = x +22
x = 2 . . . . . . . . . . . . subtract x+20
The number is x = 2.

Additional comment
The outcome in each case is 2.4.

Lets sets A and B be defined as follows:
A= {25, 26, 27, 28, 29}
B is the set of integers greater than or equal to -6 and less than or equal to 1.
(picture attached below)
a) The value sets of n(A) = 5, n(B) = 8
b) 33 ∈ A is false, -4 ∈ B is true, 25 ∈ A is true, 5 ∉ B is true.
What is set?Sets, in mathematics, are an organized collection of objects and can be represented in set-builder form or roster form. Usually, sets are represented in curly braces {}, for example, A = {1,2,3,4} is a set.
A = { 25, 26, 27, 28, 29}
B ( is greater or equal to -6 and equal to 1) = { -6, -5, -4, -3, -2, -1, 0, 1}
n(A) = number of elements in A which is 5 and n(B) = 8
33 ∈ A The symbol ∈ means element of. so 33 is not an element of A.
-4 is an element of B so it is true, -4 ∈ B is true
25 ∈ A is true because 25 is an element of A
5 ∉ B is true because 5 is not an element of B
In conclusion, n(A) = 5, n(B) = 8
-4 is an element of B so it is true, -4 ∈ B is true
25 ∈ A is true because 25 is an element of A
5 ∉ B is true because 5 is not an element of B

Expand the brackets in each expression and then
combine like terms where possible.
a -7(7a + 4b) + 10a - 10b
4x-10 y
b 6(2x+6y) -
The expanded form of 7(7a + 4b) + 10a - 10b and 6(2x+6y) will be 59x+18b and 12x+12y.
What is expanded form?
The expanding form can be used to indicate the value of each digit in a number in arithmetic. Numbers that are expressed as the sum of each digit multiplied by its place value are known as expanded numbers.
It is given that,
a) 7(7a + 4b) + 10a - 10b
b) 6(2x+6y) -
a)
[tex]=7(7a + 4b) + 10a - 10b \\\\ =49a+28b+10a-10b \\\\ =49a+10a+28b-10b \\\\ =59a+28b-10b \\\\ =59a+18b[/tex]
b)
= 6(2x+6y) -
=12x+12y
Thus, the expanded form of 7(7a + 4b) + 10a - 10b and 6(2x+6y) will be 59x+18b and 12x+12y.

Two triangles are shown below. 3 5 15 9 6 18 Which statement best describes the relationship between the two triangles ? The triangles are not similar all corresponding angles are not equal . The triangles are not similar ; all corresponding sides are not proportional . The triangles are similar ; the similarity ratio is 1: 3. The triangles are similar ; the similarity ratio is 2 :3.
The statement that best describes the relationship between the two triangles is the option;
The triangles are not similar; all the corresponding sides are not proportionalWhat are the conditions for the similarity of two triangles?Two triangles are similar if they satisfy the following conditions.
Two angles of one triangle are congruent to two angles in the other triangle (AA, Angle-Angle similarity postulate)Two sides of one triangle are proportional to two sides of the other triangle and the included angle of the two sides in each triangle are congruent (SAS, Side-Angle-Side similarity postulate)The three sides of one triangle are proportional to the three sides of the other triangle (SSS, Side-Side-Side, similarity postulate)The length of the sides of the triangles are;
First triangle, a₁ = 3, b₁ = 5. c₁ = 15
Second triangle. a₂ = 9, b₂ = 6, c₂ = 18
The ratio of the corresponding sides is therefore;
[tex]\dfrac{a_1}{a_2} = \dfrac{3}{9} =\dfrac{1}{3}[/tex]
[tex]\dfrac{b_1}{b_2} = \dfrac{5}{6}[/tex]
[tex]\dfrac{c_1}{c_2} = \dfrac{15}{18} =\dfrac{5}{6}[/tex]
The ratio of the three corresponding sides of the triangles are not the same such that the corresponding sides of the triangles are not constantly proportional.
Therefore the two triangles are not similar because all the corresponding sides are not proportional.

I've been stuck on this problem for awile can anyone help?
7z-4=12+3z
Answer:
z = 4
Step-by-step explanation:
7z - 4 = 12 + 3z
1) We want to first move the z values to one side of the equation. This means we would subtract 3z from both sides to move it to the left side. This would give us 4z - 4 = 12.
2) We then want to isolate the z value. This means we want to move the -4 to the right side. We would add 4 to both sides and get 4z = 16.
3) We can then divide both sides by 4 and get the value for z.
This gives us z = 4.
