[a] x = 175 - 7.5p

For a, we are isolating the x variable to one side of the equation.

0.4x + 3p = 70

0.4x = - 3p + 70

x = - 7.5p + 175

[b] x = 115

For b, we are solving for x when p = 8.

x = - 7.5p + 175

x = - 7.5(8) + 175

x = 115

Answer:

583

Step-by-step explanation:

The mean of a data set is the average of the data set. It can be found by adding up all of the values and then dividing by the total number of values added. In this case, one is given the mean, and one needs to find a missing value. Since there is a missing element, add one to the total number of values in the data set. The missing element is represented by the parameter (x). Set up an equation and solve:

$\frac{(236)+(342)+(328)+(352)+(352)+(306)+(317)+(x)}{8}=325\\$

Simplify,

$\frac{2233+x}{8}=352$

Inverse operations,

$2233+x=2816\\\\x = 583$

Write the equation of the following graph in intercept form.

Kobotan [32]

Answer:

A) $f(x)=0.2(x+2)(x-5)$

Step-by-step explanation:

The graph has x-intercepts at $x=5$ and $x=-2$ , so our factors for the polynomial will be $x+2$ and $x-5$ . This means we can rule out options B and D.
