Answer:
-49
Step-by-step explanation:
multiply 7 with 7 then i with i and lastly multiply the result numbers
7i × 7i ➡ 7 × 7 = 49
i × i = i^2
49 × i^2 = 49i^2
i^2 = -1 ➡ 49 × (-1) = -49
D. Subtract 2 from the number of sides and multiply the difference by 180
Answer:
slope = - 
Step-by-step explanation:
Calculate the slope m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (- 3, 4) and (x₂, y₂ ) = (4, - 1)
m =
= - 
<span>2x-4y=32
2x-8y=48
--------------subtract
4y = - 16
y = -4
</span>2x-4y=32
2x- 4(-4)=32
2x + 16 = 32
2x = 16
x = 8
answer
(8, -4)
