What is the value of this expression when x=-6andY=-1/2

Let x = -6 and y = -1/2

4[(-6)^2 + 3)] - 2(-1/2)

4[(36 + 3)] + 1

4(39) + 1

156 + 1

157

g = (2, 2)

step-by-step explanation:

given the ratio is 1 : 1 then f is the midpoint of eg

let the coordinates of g = (x, y)

using the midpoint formula

(0 + x) = 1 ( multiply both sides by 2 )

0 + x = 2 ⇒ x = 2

similarly

(4 + y) = 3 ( multiply both sides by 2 )

4 + y = 6 ( subtract 4 from both sides )

y = 2

coordinates of g = (2, 2)
