Hello!

<h2>Answer:</h2>

The correct answer is option four, 27.

<h2>Explanation:</h2>

We know that a = 9.

Because the a is right next to the 7 and the 4, this indicates that it is being multiplied.

7a - 4a

Substitute for the 'a'.

= 7(9) - 4(9)

= 63 - 36

= 27

Answer:

The answer is 27

Step-by-step explanation:

The reason being, you can solve this 2 ways.

1) Combine like terms, 7a-4a = 3a.

Now just substitute (a=9) into 3a.

3 * (9) = 27.

2) Or just substitute a = 9 into the original expression.

7 * (9) - 4 * (9)

= 63 - 36 = 27

15/5 = 3

Flour = 3/8 x 3 = 9/8 = 1 1/8 cups.

Chocolate chips = 1/2 x 3= 3/2 = 1 1/2 cups.

Butter = 4/5 x 3 = 12/5 = 2 2/5 cups.

Teaspoons of salt = 4/16 = 1/4 = 1/4 x 3 = 3/4

Earthworms = 1.5 = 3/2 x 3 = 9/2 = 4 1/2 cups.

The length of one leg of a right triangle is 24 feet and the length of the hypotenuse is 40 ft what is the length of the other l
Rama09 [41]
To solve for the other leg, you need to use Pythagorean theory.

The theory states that C^2 = A^2 + B^2

In your case, you have to solve for B.
C = 40 (hypotenuse)   A = 24 (leg 1)

The formula rewritten for B is b= \sqrt{c^{2}-a^{2} }

Now, you can solve.

b= \sqrt{c^{2}-a^{2} }&#10;&#10;b= \sqrt{40^{2}-24^2 }&#10;&#10;b = \sqrt{1600 - 576}&#10;&#10;b = \sqrt{1024}&#10;&#10;b = 32

Therefore, B = 32.

So the second leg is 32 feet.

The graph is vertically stretched by a factor of 2 and translated 3 units right when it is transformed. Option A is correct.

<h3>What is transformation of a function?</h3>

Transformation of a function is shifting the function from its original place in the graph.

Types of transformation-

  • Horizontal shift- Let the parent function is f(x). Thus by replacing parent function with f(x-b) shifts the graph b units right and by replacing parent function with f(x+b) shifts the graph b units left.
  • Vertical shift- Let the parent function is f(x). Thus by replacing parent function with f(x)-c shifts the graph c units down and by replacing parent function with f(x)+c shifts the graph c units up.

The given function is,

f(x) = x^3

This function is changed to the function,

g(x) = 2f(x -3),

Here the 3 units is substrate in the function. Thus, it is shiftet 3 units right. The number 2 is multiplied in the function which vertically stretched the graph by a factor of 2.

Thus, the graph is vertically stretched by a factor of 2 and translated 3 units right when it is transformed. Option A is correct.

I really need this please don’t answer it wrong!
enyata [817]

Answer:

Step-by-step explanation:

Squaring a^(-2) results in a^(-4).

Squaring 8^7 results in 8^14.

Putting these factors together, we get

8^14

-------                     this is equivalent to Answer C.

a^4
