the place i got this from tbh i don't understand what you want for an answer but i tried, so here is a website that i got these from i hope it helps you.
Step-by-step explanation:
Evaluate for a= 1/3
3(1/3)+4(1/3) = 7/3
Evaluate for a= 1.5
(3)(1.5)+(4)(1.5)
=10.5
Evaluate for a=
(3)(2)+(4)(2)
=14
the answers are -12x^2 and 4x^2y. hopefully it helps and i just got it right.
Answer:
x = 
Step-by-step explanation:
Given
Ax + By = C ( subtract By from both sides )
Ax = C - By ( divide both sides by A )
x = 
The image of the point (x, y) by R (90, O) is (-y, x)
Point R = (1, -1), then
Point R' = (1, 1)
Point S = (4, 1), then
Point S' = (-1, 4)
Point T = (4, -3), then
Point T' = (3, 4)
The answer is D
