Answer:
C. ∠EBC
Step-by-step explanation:
Hope this is correct and if it helps :))
First, let's declare some variables.
x = # of sticker packs
y = total # of stickers
Now, let's create an equation to model the problem.
y = 21x + 8
Let's plug in 50 for y and solve for x.
50 = 21x + 8
Subtract 8 from both sides.
42 = 21x
Divide both sides by 21
2 = x
Anthony will have to buy 2 sticker packs to have a total of 50 stickers.
Answer: 
Step-by-step explanation:
You need to use the following formula for calculate the area of a square:

Where "s" is the lenght of any side of the square.
You know that the area of a mural is
. Then, you can substitute this area into the formula and solve for "s", in order to find the side lenght of the mural.
Therefore, this is:

X/5 + 7 = 14
Subtract 7 from each side:
X/5 = 7
Multiply both sides by 5:
x = 7 * 5
X = 35
Solutions
You have been given the y-intercept of -4. The meaning of this is that the given line will go through the point (0, -4). Plug in 1 for x and find y.
