Which expression best represents the cube

Answers

Step-by-step explanation:

The following is a list of perfect Cubes

13 = 1

23 = 8

33 = 27

43 = 64

53 = 125

63 = 216

73 = 343

83 = 512

93 = 729

103 = 1000

If a variable with an exponent has an exponent which is divisible by 3 then it is a perfect cube. To get the cube root, we simply divide the exponent by 3. For example x9 is a perfect cube, its cube root is x3 . x11 is not a perfect cube.

Answer:

$(g\ o\ f)(x) = -10x^2 + 25x + 44$

Step-by-step explanation:

Given

$f(x) = 2x^2 - 5x - 8$

$g(x) = -5x+4$

Required

$Find:\ (g\ o\ f)(x)$

In functions;

$(g\ o\ f)(x) = g(f(x))$

Substitute $f(x) = 2x^2 - 5x - 8$ in $(g\ o\ f)(x) = g(f(x))$

$(g\ o\ f)(x) = g(f(2x^2 - 5x - 8))$

Solving for $g(f(2x^2 - 5x - 8))$

If $g(x) = -5x+4$

then

$g(f(2x^2 - 5x - 8)) = -5(2x^2 - 5x - 8) + 4$

Open Bracket

$g(f(2x^2 - 5x - 8)) = -10x^2 + 25x + 40 + 4$

$g(f(2x^2 - 5x - 8)) = -10x^2 + 25x + 44$

Recall that:

$(g\ o\ f)(x) = g(f(2x^2 - 5x - 8))$

This implies that

$(g\ o\ f)(x) = -10x^2 + 25x + 44$

If X equals 6 then find the matching value for y 4x-3y=9

Answers

Answer:

Y = 5

Step-by-step explanation:

Since we know six is the value of X we can go ahead and multiply 4 and 6

4 X 6 = 24

Now there are different ways to find the value of Y

How I find the value is I subtracted 24 from 9

That gives you 15

Next you find what number you need to multiply by 3 to get 15

In this case your answer is 5

Then to be extra sure subtract 24 and 15 and you'll get 9

Hope this helps!

y = 5

substitute x = 6 into the equation and solve for y

(4 × 6 ) - 3y = 9

24 - 3y = 9 ( subtract 24 from both sides )

- 3y = - 15 ( divide both sides by - 3 )

y = 5
