Answer:

=−x2+11x−10

Step-by-step explanation:

Let's simplify step-by-step.

9(x−1)−(x−1)2

Distribute:

=(9)(x)+(9)(−1)+−x2+2x+−1

=9x+−9+−x2+2x+−1

Combine Like Terms:

=9x+−9+−x2+2x+−1

=(−x2)+(9x+2x)+(−9+−1)

=−x2+11x+−10

Answer:

$\large\boxed{a.\ -30}$

Step-by-step explanation:

$\dfrac{y}{3}+8=-2\qquad\text{subtract 8 from both sides}\\\\\dfrac{y}{3}+8-8=-2-8\\\\\dfrac{y}{3}=-10\qquad\text{multiply both sides by 3}\\\\3\!\!\!\!\diagup^1\cdot\dfrac{y}{3\!\!\!\!\diagup_1}=(3)(-10)\\\\y=-30$

Can anyone help please?

Answer:

A'(-3, 12)
B'(9, 6)
C'(-6, -6)

Step-by-step explanation:

Dilation about the origin multiplies each coordinate value by the dilation factor.

For dilation factor k, the new coordinates are ...

(x, y) ⇒ (kx, ky)

Your dilation factor is 3, so the transformation is ...

(x, y) ⇒ (3x, 3y)

A(-1, 4) ⇒ A'(-3, 12)

B(3, 2) ⇒ B'(9, 6)

C(-2, -2) ⇒ C'(-6, -6)

Which of the following inequalities is not true?

Galina-37 [17]

The answer is C or the third answer choice because the absolute value of nine is equivalent to the absolute value of nine. The meaning of absolute value is the number of places away from zero on the number line, and both 9 and -9 are equal distance from zero.
