Help answer please. The graph of g and the graph of fare shown. Which of the following describes a single transformation that compares the graph of g with the graph of f?
Select all that apply.
The options that describes a single transformation that compares the graph of g with the graph of f are;
B) The graph of g is shifted 3 units right.
C) The graph of g is shifted 3 units up.
What is the Graph Transformation?Transformation is a method required to resize or change the orientation of a given shape or figure. The types of transformation are translation, reflection, rotation, and dilation.
Translation is a method of transformation that involves moving an object or shape from one point to another without changing any dimension.
Reflection is a method of transformation that involves flipping a given figure about a given reference point or line. In order words, a mirror image of the original object.
Rotation is a method of transformation that involves turning a given figure at an angle about a reference point.
Dilation is a method of transformation whereby the length of the sides of the figure is either increased or decreased.
Now, looking at the given graph, we see that the line showing the graph g is clearly shifted by either 3 units to the right or 3 units upwards to get the function line f.

The equation of the revenue is y = -500/3x + 3000 and the daily sales for $7.50 is $1750
How to determine the equation of the line?The points are given as
(6, 2000) and (8, 1000)
Calculate the slope of the points using the following slope formula
m= (y₂ - y₁)/(x₂ - x₁)
Where
(x, y) = (6, 2000) and (8, 1000)
Slope = m
So, we have
m = (1000 - 2000)/(8 - 2)
Evaluate the expression
m = -500/3
The equation of the line is then calculated using the line equation formula
y = m(x - x₁) + y₁
Where
(x₁, y₁) = (6, 2000)
So, we have
y = -500/3(x - 6) + 2000
Expand
y = -500/3x + 3000
The daily sales for $7.50This means that
x = 7.50
Recall that
y = -500/3x + 3000
Substitute x = 7.50
y = -500/3 x 7.50+ 3000
Evaluate
y = 1750
So, the daily sales is $1750

Using the law of sines, the remaining angles and sides of the triangle are given as follows:
[tex]\beta = 20^\circ[/tex]a = 8.2.b = 6.What is the law of sines?Suppose we have a triangle in which:
Side with a length of a is opposite to angle A.Side with a length of b is opposite to angle B.Side with a length of c is opposite to angle C.The lengths and the sine of the angles are related according to the equation presented as follows:
[tex]\frac{\sin{A}}{a} = \frac{\sin{B}}{b} = \frac{\sin{C}}{c}[/tex]
The remaining angle measure is given as follows:
[tex]\beta = 180 - (132 + 28) = 20^\circ[/tex]
(this is because the sum of the internal angles of a triangle is of 20º).
Then side a is calculated from the law of sines as follows:
sin(28º)/a = sin(132º)/13
a = 13sin(28º)/sin(132º)
a = 8.2.
Side b is also calculated from the law of sines, as follows:

Answer:
x = -72
Step-by-step explanation:
3(2x + 11) + 4(2x + 3) = 9(2x + 13) - 3x

Answer:
0.1468 ohms per second
Step-by-step explanation:
You want the rate of change of R when ...
1/R = 1/r1 +1/r2r1 = 70 Ωr2 = 120 Ωr1' = 0.3 Ω/sr2' = 0.2 Ω/sDerivativeThe desired rate of change is the derivative of R with respect to time. Implicitly differentiating the given relation with respect to time, we have ...
-R'/R² = -r1'/r1² -r2'/r2²
R' = R²(r1'/r1² +r2'/r2²)
Using the given relation and values, we have ...
1/R = 1/70 +1/120 = 190/(70·120)
R = (840/19)
R' = (840/19)(0.3/70² +0.2/120²) = 53/361 ≈ 0.1468
The rate of change of R is about 0.1468 ohms per second.

Answer:
34 degrees
Explanation;
Using the theorem below to solve the problem;
Angle at the vertex is equal to to half of the difference of angles of its intercepted arcs
Angle at the vaertex = z
difference of angles of its intercepted arcs = 108 - 40
difference of angles of its intercepted arcs = 68
Using the theorem
z = 1/2(108-40)
z = 1/2 * 68
z = 34 degrees
Hence the value of z is 34 degrees

B(3,3)
C(3,-3) and
D (-3,-3)
One diagonal is line AC.
Find the slope of AC:
[tex]m\text{ = }\frac{y2-y1}{x2-x1}=\text{ }\frac{-3-3}{3-(-3)}=\frac{-6}{6}=\text{ -1}[/tex]Solpe of AC = -1

y = -x + b
The equation for AC:
y = -x
The other diagonal is BD.
find the slope of BD:
[tex]m\text{ = }\frac{y2-y1}{x2-x1}=\text{ }\frac{-3-3}{-3-3}=\frac{-6}{-6}=\text{ 1}[/tex]Slope of BD = 1

The answer is
-9,-4,-2,2,12Identify the slope and y-intercept from the graph, and then write the equation of the line. YA 3) 1. slope = y-intercept= y =
As shown on the graph:
y-intercept is the value of y at which x = 0
so, from the graph when x = 0 , y = -3
To find the slope use two points to calculate it
Using the points (0 , -3) and ( 4 , 4 )
the slope = Rise/Run
Rise = 4 - (-3) = 4 + 3 = 7
Run = 4 - 0 = 4
so, the slope = 7/4
The slope intercept form of the line is y = mx + c
Where m is the slope and c is y-intercept
Slope = m = (7/4)
y-intercept = c = -3
So,
y = (7/4) x - 3

SOLUTION:
Step 1;
In this question, we are given the following;
Jessica used 2/3 yard of fabric to make scarf can she make 2 of these scarfs with 1 3/4 yards of fabric, and why?
Step 2:
The details of the solution are as follows;
B.__ angles form a straight line.
Complete the sentences
A. All right angles are 90 degrees (by definition)
B. supplemenatry angles form straight line (by definition)
C. If two angles form a linear pair, then the are supplementary (by definition)
D. When two lines intersect, the inverse angles are congruent.
In the given image of two intersecting lines, you have m∠1 = 67°
E. angle 2 and angle 1 are supplementary, then;
m∠2 + m∠1 = 180°
m∠2 = 180° - m∠1
m∠2 = 180° - 67°
m∠2 = 113°
F. angle 3 and angle 1 are congruent, then:
m∠3 = m∠1 = 67°
Due to the given image, you have the following expressions:
2x + x + 60° = 180° supplementary angles
3x + 60° = 180° subtract 60 both sides
3x = 180° - 60°
3x = 120° divide both sides by 3
x = 120/3
x = 40°
Furthermore, for y, you have:
x + y + y + 20° = 180° supplementary angles
x + 2y + 20° = 180° replace x = 40
40 + 2y + 20° = 180°
2y + 60° = 180° subtract 60 both sides
2y = 180° - 60°
2y = 120°
y = 120/2 divide by 2 both sides
y = 60°
Answer: 180 degree's make up a straight line.
