Answer:

-40x³ + 44x² - 66x - 36

Step-by-step explanation:

f(x) = 10x + 4

g(x) = -4x² + 6x – 9

Therefore:

f(x) · g(x) = (10x + 4) · (-4x² + 6x - 9) = -40x³ + 44x² - 66x - 36

It's in the picture ?

nignag [31]

Answer:

Step-by-step explanation:

From first piece -6 < x ≤ 0.

From second piece 0 < x ≤ 4.

Therefore -6 < x ≤ 4 → x ∈ (-6, 4]

-7 ∉ (-6, 4]

-6 ∉ (-6, 4]

4 ∈ (-6, 4]

5 ∉ (-6, 4]

Wade was asked to solve this inequality:

frozen [14]

Answer:

The correct option is Option A: Yes, that is the correct step

Step-by-step explanation:

Wane was asked to solve the inequality $\large \frac{x}{3}\ge11$

He decides that he needs to multiply both sides by 3.

We need to tell if the step is correct?

So, solving the inequality

$\frac{x}{3}\ge11$

We need to multiply both sides by 3, to get value of x i.e.

$\frac{x}{3}*3\ge11*3\\x\geq 33$

So, Wanes step is correct.

The correct option is Option A: Yes, that is the correct step

I will give the first answer brainiest :)

Lyrx [107]

Answer:

A=2

Step-by-step explanation:

in the figure, parabola cuts the graph at point (2,1)

point (2,1) is one of the solution of the given quadratic equation

Hence, we can find the value of a by putting the value of x and y, we get

1=a(2-3)^2-1

= 2=a

Which is why A is 2
