In this problem we can see that the intercept with the y axis is positive one, so we know that the answer is A) or D), now we can see that the slope is positie so the term with the x has to be positive so the correct function is:
[tex]y=x+1[/tex]Find the constant of proportionality, then write an equation relating x and yy is directly proportional to x, and y = 81 when x = 9
When x=9, y=81.
To find the proportionality constant take the ratio of y/x.
[tex]\begin{gathered} \frac{y}{x}=\frac{81}{9} \\ =9 \end{gathered}[/tex]Thus, the proportionality constant is 9.
The relation between y and x can be determined as,
[tex]\begin{gathered} \frac{y}{x}=constant \\ \frac{y}{x}=9 \\ y=9x \end{gathered}[/tex]Thus, the required relationship between x and y is y=9x.

Legs are mentioned below.
Define triangles.A triangle is a polygon with three vertices and three sides. The angles of the triangle are formed by the connection of the three sides end to end at a point. The triangle's three angles add up to 180 degrees in total. A triangle's side is one of its legs. The term "leg" for a right triangle typically refers to a side other than the one across from the right angle (which is termed the hypotenuse). The word catheti also refers to legs.

a) AB and BC
AB = height
BC = base
b) AC and BC
AC = hypotenuse

Create a linear equation that satisfies conditions.Type your equation in the form y = mx + b if a value is not an integer then type it in as a decimal rounded to the nearest hundredth.
Solution
Part a
For the first part we have two points (2,4) and (4,10)
We can find the slope like this:
[tex]m=\frac{10-4}{4-2}=\frac{6}{2}=3[/tex]And then the intercept would be:
4= 3*2 +b
b= 4-6= -2
Then the answer is:
y= 3x -2
Part b
f(-4)=18 and f(4) =2
The slope is:
[tex]m=\frac{18-2}{-4-4}=-2[/tex]
2= -2*4 +b
b= 2+8=10
y= -2x+10
Part c
x intercept at (-5,0) and the y intercept (0,4)
[tex]m=\frac{4-0}{0+5}=\frac{4}{5}[/tex]And using the y intercept we have:

What is Equation?Two or more expressions with an Equal sign is called as Equation.
Given,
When I was 2 years my sister was twice of my age.
Let us consider the ages by using a equation like this
x/y------>X represents my age/ y represents my sister age
x/y ----->2/4=40/a
a is the age of sister when i was 40.
Now let us solve 2/4=40/a
One by two equal to forty by a.
Apply cross multiplication
2a=160
Divide both sides by 2
a=80
Hence, if I'm 40, my sister is 80 years old.

In this exercise we have eight cases of equations involving absolute values. The definition of absolute value is:

Now we proceed to resolve on each case:
Case 1
|k| = 8
k = 8 ∨ - k = 8
k = 8 ∨ k = - 8
Case 2
|x| = 7
k = 7 ∨ - k = 7
k = 7 ∨ k = - 7

a + 2 = 8 ∨ - a - 2 = 8
a = 6 ∨ a = - 10
Case 4
|8 · n| / 10 = 2
|8 · n| = 20
8 · n = 20 ∨ - 8 · n = 20
n = 20 / 8 ∨ n = - 20 / 8
n = 10 / 4 ∨ n = - 10 / 4
n = 5 / 2 ∨ n = - 5 / 2

Tarik starts his morning walk at 7:00 am, his distance, in miles to the nearby grocery store after x hours is F(x) = 3|x - 0.5| 7:15 am Tarik is {blank} away from the store?
Tarik is 0.75 miles away from the store.
How to calculate the value?It should be noted that based on the information given, the expression has been given for the hours used.
In this case, the minutes used was:
= 7.15am - 7.00am
= 15 minutes
This will be changed to hour
15 minutes = 15/60 = 0.25 hour.
The expression given is:
= 3(x - 0.5)
where x = hours used 0.25
= 3(x - 0.5)
= 3(0.25 - 0.5)
= 3(-0.25)
= -0.75
He is 0.75 miles away.

This can be solved using permutations
What are permutations?
A permutation of a set in mathematics is a loosely defined organization of its members into a sequence or linear order, or, if the set is already sorted, a rearranging of its elements. The act or process of shifting the linear order of an ordered set is often referred to as "permutation." Permutations are distinct from combinations, which are random picks of certain members of a collection. For example, there are six permutations of the set 1, 2, 3 represented as tuples: (1, 2, 3), (1, 3, 2), (2, 1, 3), (2, 3, 1), (3, 1, 2), and (3, 1, 2). (3, 2, 1). Permutations include anagrams of words with various letters.

The equation of the line is x = 2
How to determine the line equation?The slope of the line is given as
Slope = Undefined
This can be rewritten as
m = Undefined
The point on the line is also given as
(x, y) = (2, 1)
For a line with an undefined slope, it means that:
The line is a vertical line
The equations of all vertical lines are represented as
x = x₁
In this case,
(x₁, y₁) = (2, 1)
Remove the y-coordinate
x₁ = 2
Substitute x₁ = 2 in the equation x = x₁

2. In the 1936 US presidential election polls, the Literary Digest held a poll that forecast that Alfred E. Landon would defeat Franklin Delano Roosevelt by 57% to 43%. They had used lists of telephone and automobile owners to select their sample. George Gallup, using a much smaller sample (300,01 rather than 2,000,000) , predicted Roosevelt would win, and he was right. What went wrong with the Literary Digest poll?
Explanation
We can infer that the Literary Digest poll was wrong because it was biased.
We are told that the poll used lists of telephone and automobile owners to select their sample which doesn't give a full representation of all those who will vote in the election.
So we can infer that the problem with the Literary Digest poll is that it was Biased

A right triangle with vertices P(-3,9) Q(-3,5) R(-7,5) is reflected on the y-axis then the image is rotated 180 degrees about the origin. What are new coordinates of the right triangle?
We could start by drawing the triangle we are given. However, it would be better to draw the triangle after the y-axis reflection. To calculate the y-axis reflection, we first think as follows
We see that the reflected point is at the same height as the original point. This means that the y coordinate should remain the same. So, the only thing that changed is the x coordinate. This suggests that, to calculate the reflection about the y-axis, we simply multiply by -1 the first coordinate. So, after the reflection we get the points
P'(-3*(-1),9)=(3,9)
Q'(-3*(-1),5)=(3,5)
R'(-7*(-1),5) =(7,5)
Now, if we plot this points we get
So, if we rotate this 180° we would get the following
So the new points after rotating 180°, would be
P''(-3,-9)
Q''(-3,-5)
R''(-7,-5)
Amanda has scored 24,22,27,23 and 30 points in her five basketball games so far. How many points does she need to score in her next game so that her average (mean) is 25 points per game?
To answer this question, we need to remember that the mean of a data is the sum of the data divided by the total number of elements that represent this data.
Therefore, if we need to find the sixth value for which the average (mean) per game is 25 points, we can proceed as follows:
[tex]\frac{24+22+27+23+30+x}{6}=25[/tex]Now, to find the value, x, we need to follow the next steps:
1. Add the values in the numerator of the fraction:
[tex]\frac{126+x}{6}=25[/tex]2. Multiply both sides by 6:
[tex]\begin{gathered} \frac{6\left(126+x\right?}{6}=6\left(25\right? \\ \frac{6}{6}\left(126+x\right?=150 \\ 126+x=150 \end{gathered}[/tex]3. Finally, subtract 126 from both sides of the equation:
[tex]\begin{gathered} 126-126+x=150-126 \\ x=24 \end{gathered}[/tex]Therefore, the value she needs is 24 points.
And we can check this value as follows:
[tex]\frac{24+22+27+23+30+24}{6}=\frac{150}{6}=25[/tex]Therefore, in summary, we have that Amanda needs to score 24 points in the next game so that her average is 25 points per game.
