The x has an exponent of 2. the exponent of 2 means x squared, which is x•x. this isn't the same as x+x, because x+x=2x whereas x•x=x squared.
Answer:
A' = (6, 15)
Step-by-step explanation:
We consider the center point of dilation to be the origin (0,0)
so point A(-2, -5) to A' by scale factor N = -3 means
A' = (-2*(-3), -5*(-3)) = (6, 15)
3(y - ¹/₇) - y = 4(2 - y)
3(y) + 3(⁻¹/₇) - y = 4(2) + 4(-y)
3y + (⁻³/₇) - y = 8 + (-4y)
3y - ³/₇ - y = 8 - 4y
3y - y - ³/₇ = 8 - 4y
2y - ³/₇ = 8 - 4y
<u>+ 4y + 4y</u>
6y - ³/₇ = 8
<u> + ³/₇ + ³/₇
</u> <u>6y</u> = <u>8³/₇
</u> 6 6<u>
</u> y = 1¹⁷/₄₂
You would have to multiply 3.14x29.8 which is 93.572, or 93.6 to the nearest tenth
