Each statement describes a transformation of the graph of y = x. Which statement correctly describes the graph of y = x + 10?
A. It is the graph of y = x translated 10 units to the right.
B. It is the graph of y = x where the slope is increased by 10.
C. It is the graph of y = x translated 10 units up.
D. It is the graph of y = x translated 10 units down.
Answers
Answer:
C
Step-by-step explanation:
since it is the slope form y = mx+b
b = y axis
so in order to go up you have to translate upwards

Explanation:
Use the area of a triangle formula which is, A=1/2bh. You will get A=1/2(6)(3).
Answer:
1. 672 inches
Step-by-step explanation:
Question #1
The formula for the volume of a triangular prism is:
V = [tex]\frac{bh}{2}[/tex]
Where V is the volume, b is the area of the base, and h is the height. You are given the volume and the height. Plug those numbers into your equation.
[tex]4704 = \frac{b(14)}{2}[/tex]
Now, solve for b. To do this, you must isolate the variable b.
The first step to do this is to multiply both sides by 2. This will get you:
4704(2) = 14b
9408 = 14b
Now, divide both sides by 14 to get:
672 = b.
Therefore, the area of the base is 672 inches.
Question #2
To solve this problem, separate the figure into 2 shapes. You have a triangle with a base of 6 cm and a height of 6 cm, as well as a semicircle with a radius of 3 cm.
After you do this, find the area of each shape separately.
The formula for the area of a triangle is:
[tex]A = \frac{bh}{2}[/tex],
where A is the area, b is the length of the base, and h is the height. You know the base and the height, so plug those into your equation. You will get:
[tex]A = \frac{6*6}{2}\\\\A = \frac{36}{2}\\\\A = 18[/tex]
Now you know that the area of the triangle is 18 cm^2.
Let's find the area of the semicircle.
The formula for the area of a semicircle is:
A = [tex]\frac{1}{2}[/tex]π[tex]r^2[/tex]
You know the radius, so plug that in to get:
A = [tex]\frac{1}{2}[/tex]π([tex]3^2[/tex])
A = [tex]\frac{1}{2}[/tex]π(9)
Simplify this to get:
A = 4.5π.
Now, either multiply 4.5 by π to get:
14.1371669412 cm^2
or, multiply 4.5 by 3.14 to get:
14.13 cm^2.
Then, add the area of the triangle, 18 cm^2, by the area of the triangle, 14.13, to get:
32.13 cm^2.
Hope this helps!

When you use a photocopier to enlarge an image, the whole image becomes bigger by a certain percentage. In this problem, the biggest the enlargement can go each time is 140%. For example, a one inch segment can be turned into a 1.4 inch segment. The picture above shows two circles. The photocopier had to be used twice to get from the first image to the second image. If the photocopier used the same percentage both times, what is that percentage?

The actual tiles have length
and width
. What is the ratio of the length of a tile in the model to the length of an actual tile? What is the ratio of the area of a tile in the model to the area of an actual tile? Use pencil and paper. Describe two ways to find each ratio.
Answers
The two ways to find the ratio of the length is to turn the inches into feet or the feet into inches
So the answer can be solved like this:
1/36ft to 1/4ft which is 9:1 (blueprint size to actual size)
or
1/3in to 3in which is also 9:1 (blueprint size to actual size)
