The vertices of triangle FGH are f(-2,1) G(1,3) and H((0,5) what are f'G'h' for a reflection over the y-axis? A. F'(-2,-1) G'(-1,-3) H(0,-5) B. F'(2,1) G(-1,3) H(0,5) C. F'(2,-1) G'(1,3) H'(0,-5) D'(-2,1) G'(1,3) H'(0,5)

Given:

The vertices of triangle FGH are F(-2,1), G(1,3) and H(0,5).

To find:

The vertices of F'G'H' for a reflection over the y-axis.

Solution:

If a figure is reflected over the y-axis, then

Using this rule of reflection, we get

Similarly,

The vertices of F'G'H' are F'(2,1),G'(-1,3), H'(0,5). Therefore, the correct option is B.

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!
