Answer:

14.

There are twice as many flute players as there are trumpet players, so f = 2 × 5

15.

Let the cost of 1 tickets = be x then the equation of total cost is:

8 × x = 208

Solve for x:

x = 208/8

x = 26

Each ticket costs $26.

16.

Let the low temperature be x then the equation for high temperature is:

x + 24 = 92

Solve for x:

x = 92 – 24

Evaluate:

x = 68

The low temperature was 68°F.

17. A number is checked if it is a solution of an equation or not by substituting its value in the equation and simplifying it. If the left and right hand side of the equation are equal then the number is a solution of the equation otherwise not.

What is 7 (1+10p) + 8 (1 + 6p)

Komok [63]

Answer:

58p+15

Step-by-step explanation:

First, we want to get rid of the parentheses in the equation. To do that, let's start with 7(1+10p). We multiply 7 by each item in the parenthesis, and get 7+70p. Keep that little thing in mind, we will use it later. Next, same process with the other part, and we get 8+48p. We multiplied both parts out, so now we just add like terms. 7 and 8 don't have letters, so we add them to get 15. 10p and 48p do have letters, so we add those together and get 58p. We can't add that to the other numbers, because 58p is 58 times p, and 15 doesn't have that p so it wouldn't work without knowing p. What we are left with, by simplifying the problem, is 58p+15, or 15+58p. The order doesn't matter, as long as you have that answer.

Calculate the average rate of change for the function

mezya [45]

$slope = m = \cfrac{rise}{run} \implies \cfrac{ f(x_2) - f(x_1)}{ x_2 - x_1}\impliedby \begin{array}{llll} average~rate\\ of~change \end{array}\\\\[-0.35em] \rule{34em}{0.25pt}\\\\ f(x)= 2(x-2)^2+1\qquad \begin{cases} x_1=-2\\ x_2=4 \end{cases}\implies \cfrac{f(4)-f(-2)}{4-(-2)} \\\\\\ \cfrac{[2(4-2)^2+1]~~ - ~~[2(-2-2)^2+1]}{4+2}\implies \cfrac{[9]~~ - ~~[33]}{6}\implies \cfrac{-24}{6}\implies -4$

How to graph {3x-8y = 29

labwork [276]

<span>How to graph {3x-8y = 29 3x+y = -2}
</span> The first thing you should do is to clear "y". Then, you must substitute values of x in the equation to find the values of "y". Finally, graph the points obtained. (see graphic)
How do you convert this to slope intercept form? 3x-8y = 29 ---> y = 0.375x - 3.625 3x+y = -2 ---> y = -3x - 2
