Plz help no links :)
Ilya [14]

Answer:

C) f(x) = 6.25x + 3

Step-by-step explanation:

In order to know which one of the functions could produce the results in the table we simply need to substitute the number of candy bars for x in the function and solve it to see if it provides the correct total weight shown in the table. If we do this with the functions provided we can see that the only one that provides accurate results would be

f(x) = 6.25x + 3

We can input the # of candies for x and see that it provides the exact results every time as seen in the table.

f(x) = 6.25(1) + 3 = 9.25

f(x) = 6.25(2) + 3 = 15.50

f(x) = 6.25(3) + 3 = 21.75

f(x) = 6.25(4) + 3 = 28

Explain how to isolate the variable in the equation -2/3n + 7 = 15
vodka [1.7K]

Answer:

n = -12

Step-by-step explanation:

(-2/3)n + 7 = 15          

(-2/3)n+7-7 = 15-7               Subtract by 7 on both sides

(-2/3)n = 8                         Multiply by the reciprocal of the fraction, which is                                                                                                  

(-2/3)n*(-3/2) = 8(-3/2)      This makes it so you get n *1 and isolates n.

n = -24/2 = -12
