Answer:

1.875

Step-by-step explanation:

the average rate of change of g(x) in the closed interval [ a, b ] is

\frac{g(b)-g(a)}{b-a}

here [a, b ] = [- 1, 3 ] , then

g(b) = g(3) = 2³ + 1 = 8 + 1 = 9

g(a) = g(- 1) = 2^{-1} + 1 = \frac{1}{2} + 1 = 1.5

then

average rate of change = \frac{9-1.5}{3-(-1)} = \frac{7.5}{4} = 1.875

Б) 3х2 – 10 = 152<br>how to solve with square root​
Tju [1.3M]

Answer:

3\sqrt{6}  and  -3\sqrt{6}

Step-by-step explanation:

We will take numbers to one side and variables to one side eliminate the "Square" with "Square Root" and solve for the variable x. The process is shown below:

3x^2-10=152\\3x^2=152+10\\3x^2=162\\x^2=\frac{162}{3}\\x^2=54\\x=\sqrt{54}

Now, we need to reduce the radical by using the rule shown below:

\sqrt{x*y}=\sqrt{x}  \sqrt{y}

Now,

\sqrt{54}=\sqrt{6*9} =\sqrt{6}  \sqrt{9} =3\sqrt{6}

The correct answer is  3\sqrt{6} and -3\sqrt{6}

<u>Note:</u> squaring positive and negative makes the same answer

Please help if you answer correctly I will give brainliest thank you!!!!!!!!
ivolga24 [154]

Answer:

The Answer is C

Step-by-step explanation:

3x-4y=5

2x+4y=-3

This equation is the answer to this problem because just by looking at it, you can immediately cancel out the y value and solve for x.

The other equations are wrong because their is extra work needed to eliminate the values.
