Answer:

x= -11

Step-by-step explanation:

1. Expand and distribute.

2x - 3 = 5x + 30

2. Subtract 2x from both sides.

2x - 3 = 5x + 30

-2x -2x

---------------------

-3 = 3x + 30

4 Subtract 30 from both sides.

-3 = 3x + 30

-30 -30

---------------------

-33 = 3x

6. Divide both sides by 33.

-33/3 = 3x/3

-11 = x

7. Switch sides

x = -11

Answer:

Option D. A student who studies 0 hours can expect to score about a 60 on the test

Step-by-step explanation:

we know that

The y-intercept is the value of the y-coordinate when the value of the x-coordinate is equal to zero

In this problem

The x-coordinate represent the hours spent studying

The y-coordinate represent the Test score

For x=0, y=60

That means

A student who studies 0 hours can expect to score about a 60 on the test

For # 1, the answer will be 1 because of the exponential rule $a^{0} = 1$ .

#2, the answer is going to be $x^{4}$ because of the exponential rule $a^{-b} = \frac{1}{a ^{b} }$ .

#3. I'm not sure that this could be simplified any further.

#4 To get the answer to this question, we must apply the distributive property, along with the exponential rule $a ^{m} × a ^{n} = a ^{m+n}$ . When we apply these properties, we'll get $- \frac{3}{x^4}$

For the other questions, they all apply the Laws of Exponents.
