Answer: x=−3

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

15x+9=3(2x−6)

15x+9=(3)(2x)+(3)(−6)(Distribute)

15x+9=6x+−18

15x+9=6x−18

Step 2: Subtract 6x from both sides.

15x+9−6x=6x−18−6x

9x+9=−18

Step 3: Subtract 9 from both sides.

9x+9−9=−18−9

9x=−27

Step 4: Divide both sides by 9.

9x/9 = -27/9

x=−3

Answer:

x= -3

Step-by-step explanation:

First let's work on the right side and use distributive property

15x+9= 3(2x-6)

15x+9= 6x-18

    -9         -9

15x= 6x-27

-6x  -6x

9x= -27

9x/9= -27/9

x= -3

Hope this helps!

Her mother did not gave her enough money.
each pound of bananas costs 80 cents. 5 pounds of that is $0.8 x 5 = $4.00

3241004551 [841]

ANSWER

f(3) =  - 25

EXPLANATION

We want to determine the value of f(3) that will lead to an average rate of change of 19 over the interval [3, 5].

The average rate of change of f(x) over the interval [a,b]:

=  \frac{f(b) - f(a)}{b - a}

If the average rate of change over the interval [3, 5] is 19, then;

\frac{f(5) - f(3)}{5 - 3}  = 19

From the to table f(5)=13

\frac{13 - f(3)}{2}  = 19

13 - f(3) = 19 \times 2

13 - f(3) = 38

- f(3) = 38 - 13

- f(3) = 25

f(3) =  - 25
