So this is asking the cube root of -27 then squared.
Cube root of -27=-3
And -3^2=9

So I believe your answer is 9

The function h is defined as follows.

JulsSmile [24]

Answer:

The equation you are given is a quadratic. The standard form of a quadratic is y = a(x-h)2 + k where (h,k) is the vertex of the graph, which is a parabola. Vertically moving the graph 4 units upward means that you are moving k +4 units.

y = a(x-h)2 + k standard form

y = 5x2 - 4 original equation

y = 5(x-0)2 - 4 re-written in standard form

h = 0 k = -4

Four (4) units up is k + 4--->-4 + 4 = 0.

Therefore, f(x) = 5x2 + 0--->f(x) = 5x2.

What is -x/3 = 9. Solve for x

vlada-n [284]

Note: I just noticed that you only have one negative sign. If you mean to put -9, change the sign to positive. If not, leave the answer.

Note the equal sign. what you do to one side, you do to the other. Isolate the x. First, multiply 3 to both sides

-x/3(3) = 9(3)

-x = 9(3)

-x = 27

Next, to isolate the x, divide -1 from both sides

-x/-1 = 27/-1

x = 27/-1

x = -27

-27 is your answer for x.

If △ABC is an isosceles triangle where AB¯≅AC¯, m∠A=(2x−20)°, and m∠B=(3x+5)°, then m∠C=__________°.

KengaRu [80]

Refer to the diagram shown below.

Because ΔABC is isosceles and AB = AC, therefore
m∠C = m∠B = (3x + 5)°

The sum of angles in a triangle is 180°, therefore
2(3x + 5) + 2x - 20 = 180
6x + 10 + 2x - 20 = 180
8x - 10 = 180
8x = 190
x = 23.75°

Therefore
m∠C = 3x + 5 = 3(23.75) + 5 = 76.25°

Answer: 76.25°
