2a + 2s = 32, 6a + 7s = 106

Solve for a in the first equation.

2a = 32 - 2s

a = 16 - s

Substitute a into the second equation.

6(16 - s) + 7s = 106

96 - 6s + 7s = 106

96 + s = 106

s = 10

Substitute s into the first equation.

2a + 2(10) = 32

2a + 20 = 32

2a = 12

a = 6

a = 6, s = 10

Determine the intervals on which the function is increasing, decreasing, and constant. (5 points)
Luden [163]

Answer:

B. Increasing in x < -1 and decreasing in x > -1.

Step-by-step explanation:

We are given the graph of a function and is required to find the interval in which the function is increasing, decreasing or constant.

Now, from the graph we can see that the critical point i.e. the point at which the graph changes the direction is x = -1.

We observe that the function on the left side of x = -1 is going upwards to reach the point x = -1 and the function on the right side of x = -1 is going downwards.

Hence, we get that the function in increasing in x < -1 and decreasing in x > -1.

<h3>How to use mathematical word to describe an expression</h3>

The mathematical expression is 27x + 6x.

Mathematical expression are combinations of numbers and variables ordered with operations.

Mathematical expression is a combination of numbers, variables, operators (such as addition, subtraction, multiplication or division etc.).

For the given case, the terms are 27x and 6x and the expression formed from them is 27x + 6x.

This simply implies both terms are summed together to give the expression 27x + 6x.

Therefore, the mathematical word describing  both 27x and 6x in the expression  is "addition" or "sum"
