Triangle ABC is located at A (−2, 2), B (−2, 4), and C (0, 0). The triangle is then transformed using the rule (x+3, y−2) to for

Dominik [7]

Answer:

A'(1, 0 ), B'(1, 2 ), C'(3, - 2)

Step-by-step explanation:

using the rule, add 3 to the x-coordinate and subtract 2 from the y- coordinate of the original points.

A' = (- 2 + 3, 2 - 2 ) = A'(1, 0 )

B' = (- 2 + 3, 4 - 2 ) = B'(1, 2 )

C' = (0 + 3, 0 - 2 ) = C'(3, - 2 )

Given f(x) = −9x5 − x4 + 3x3 − 8 and g(x) = −9x5 − 3x3 − 9x2 + 7, find and simplify f(x) − g(x)

KatRina [158]

F(x) − g(x) =  −9x^5 − x^4 + 3x^3 − 8 − (<span>−9x^5 − 3x^3 − 9x^2 + 7)
</span>f(x) − g(x) =  −9x^5 − x^4 + 3x^3 − 8 + 9x^5 + 3x^3 + 9x^2 − 7
f(x) − g(x) = − x^4 + 6x^3 +  9x^2 - 15
hope it helps
