I believe the correct answer is C) 36+12

The equation is 4(9+3). Because of the fact that the four is on the outside, you can distribute the it so both the 9 and the 3.

9 x 4=36
4 x 3= 12

After doing this you set up your new equation which is 36 + 12!

That’s how I got this answer, hope it helps lol.

The curve with equation y = f ( x ) is stretched so that the point (-3,-5) moves to the point (-3,-10). State in terms of f ( x

Leviafan [203]

Answer:

The transformed function is $g(x) = 2\cdot f(x)$ , $\forall\,x \in \mathbb{R}$ .

Step-by-step explanation:

Let be $f(x)$ and $g(x)$ continuous functions in x. In this case, the stretch factor consist on multiplying $f(x)$ by a scalar factor, so that:

$g(x) = k \cdot f(x)$ , $\forall\, k\in \mathbb{R}, k \neq 0$

The stretch factor is:

$k = \frac{g(x)}{f(x)}$ , $\forall\, x \in \mathbb{R}$

If $f(-3) = -5$ and $g(-3) = -10$ , then:

$k = \frac{g(-3)}{f(-3)}$

$k = \frac{-10}{-5}$

$k = 2$

The transformed function is $g(x) = 2\cdot f(x)$ , $\forall\,x \in \mathbb{R}$ .

Find the surface area of the cube.

Mrac [35]

<h3><u>Given</u>:-</h3>

$\rightarrow$ Side(a) of the cube = $\sf{\frac{1}{3}ft}$ .

$\rightarrow$ Surface Area of the cube with side $\sf{\frac{1}{3}ft.}$

<h3><u>Formula Used</u>:-</h3>

$\rightarrow$ Surface area of cube = $\sf{6a^2}$

<h3><u>Solution</u>:-</h3>

$\rightarrow$ Surface area of cube = $\sf{6a^2}$ (putting the value of a from the above given)

$\rightarrow$ $\sf{=\:6×(\frac{1}{3})^2}$

$\rightarrow$ $\sf{=\:6×\frac{1}{9}}$

$\rightarrow$ $\sf{=\:\frac{6}{9}}$

$\rightarrow$ $\sf{=\:\frac{2}{3}ft^2}$

Therefore, surface area of the given square = $\sf{=\:\frac{2}{3}ft^2}$

stilt scored 5 points less than twice the number scored by dunk. together they scored 43 points. how many points were scored by

gizmo_the_mogwai [7]

Set up a system of equations:

s = 2d - 5
s + d = 43

Where 's' represents the number of points Stilt scored and 'd' represents the number of points Dunk scored.

Plug in 2d - 5 for 's' in the 2nd equation:

s + d = 43

2d - 5 + d = 43

Combine like terms:

3d - 5 = 43

Add 5 to both sides:

3d = 48

Divide 3 to both sides:

d = 16

Plug this back into any of the two equations to find 's':

s + d = 43

s + 16 = 43

Subtract 16 to both sides:

s = 27

So Dunk scored 16 points and Stilt scored 27 points.
