<u>Answer</u>: B, (-3/2, -1)
<u>Step-by-step explanation:</u>
When you use the midpoint formula, (x1+x2/2 , y1+y2/2) you end up taking one away from -4, and dividing it by 2 (-3/2), and when you add 2 to -4, you get -2, divided by 2, is -1.

Answer:
(3, -5)
Step-by-step explanation:
The transformation ...
(x, y) ⇒ (-x, -y)
transforms your point to ...
(-3, 5) ⇒ (-(-3), -5) = (3, -5)
Answer:
(-9, 3)
Step-by-step explanation:
To rotate a point 270°:
R₂₇₀ (x, y) = (y, -x)
So the answer would be (-9, 3).
Answer:
<em>102°</em>
Step-by-step explanation:
(3x - 12)° + (2x + 2)° = 180°
5x - 10 = 180 ⇒ x = 38
m∠A = (3x - 12)°
<em>m∠A</em> = (3×38 - 12)° = <em>102°</em>
Equal to! If we have a decimal and we add a zero onto the END, the value will not change! The values will only change if you change the place values. Now, this is only with decimals!!
