Answer:
Graph A.
Step-by-step explanation:
When x is equal to 0, why has to be equal to 2. The slope also has to be 3. To find this out, we do y2-y1/x2-x1. For A, the slope is -7--4/-3--2. This is equal to -3/-1. This is equal to 3. Because y=2 when x=0. option A is correct. For option D, when x=0, y=32. Therefore, this option is not correct. For option B, when x=0, y=2 so this could be correct. Plug it into y2-y1/x2-x1. This is equal to -1-0/-1-2. This is equal to -1/-3. 1/3 is not equal 3 so this option is not correct either. When x=0, y=32 for option C. Therefore, this option is not correct. Therefore, the answer is option A.

Answer:
z−181=−170
Step 1: Add 181 to both sides.
z−181+181= −170+181
z=11
Answer: Option A
Center: (3,-2)
Radius: 6
Rewrite in standard form to find the center (h,k) and radius r.
Answer:
B. 50.24
Step-by-step explanation:
to find the area of a circle you need to use the formula
a=r²π
since the radius is 4 we put that into the equation, lets use 3.14 for pi
a=(4)²×3.14
always do exponents first
a=16×3.14
a=50.24
4+28= 32
Think of it as you have 28 apples and someone gave you 4 how many would you have
