4 (-3x - 1) = 13x + 6
GarryVolchara [31]

Answer:

x=-2/5

Step-by-step explanation:

4(-3x-1)=13x+6 ~ Distribute the 4 into the parenthesis

-12x-4 = 13x+6 ~ add 12x to both sides

-4= 25x + 6  ~ subtract 6 from both sides

-10 =25x ~ divide by 25

-10/25 = x ~ simplify the fraction by dividing the num. and den by 5

-2/5 =x

I need help is it A B C or D
harina [27]
We evaluate b^2 - 4ac.  If the answer is positive, then there are two real solutions.  If it is zero, there is one real solution.  If it is negative, there are 2 complex solutions.  In this equation, a = 1, b = 5, c = 7.  Now we plug in the numbers.

5^{2}-4*1*7=1

Because this answer is positive, there are two real solutions.

F(0) = -1/5
f(4) = 7/17

                                           f(4) - f(0)
average rate of change = -------------- 
                                             4 - 0

                                           (7/17)  - (-1/5)
average rate of change = --------------------- 
                                                    4 

                                          52/85
average rate of change = --------- 
                                            4 

                                           
average rate of change = 52/85 *4

average rate of change = 208/85
