Answer: -24

Step-by-step explanation:

We should first find the outputs to the functions f and g with inputs 3 and -1 respectively. We can do this by looking at the graph and finding the y value for each desired x value.

Thus, we can see that f(3) = -2 and g(-1) is 6.

We can replace these into the expression to get

-6*-2-6*6

We should first multiply, so we get

12 -36

-24

Hence, the answer is -24.

Answer:

Your answer is -24.

Step-by-step explanation:

Given information.

The graph of f(x) and g(x)

Solving for

-6 * f(3) - 6 * g(-1) = ?

think of f(x) = y as x is the input and y is the output.

Input a value of x into f(x) or g(x) gets us a y value.

Looking at the graph of f(3) = -2 and the graph of g(-1) = 6

Now substitute that and solve.

-6 * -2 -6 * 6 = 12 - 36 = -24

Mamont248 [21]

Answer:

x = number of pairs of sandals sold = 287

Total pair of sneakers and sandals sold = 451 pairs

Step-by-step explanation:

Sneakers = 4

Sandals = 7

Sneakers : sandals = 4 : 7

If the store sells 164 pair of sneakers

Let

x = number of pairs of sandals sold

Sneakers : sandals = 164 : x

Equate both ratios to find x

4 : 7 = 164 : x

4/7 = 164/x

4 * x = 7 * 164

4x = 1,148

x = 1,148/4

x = 287

x = number of pairs of sandals sold = 287

how many pair of sneakers and sandals does the store sell in all ?

Total pair of sneakers and sandals sold = Sneakers + sandals

= 164 + 287

= 451 pairs

Total pair of sneakers and sandals sold = 451 pairs
