Solve for x:<br> x(8 + 2) + 3 = 2(5 + x) + 5(x + 1)

Write the standard form of the line that passes through the given points.<br> 4, 7) and (0, 7)

zubka84 [21]

(4,7)(0,7)

notice how ur points have the same y values....this means this is a horizontal line with a slope of 0.

equation is : y = 7...or y = 0x + 7...but we need it in standard form...
0x + y = 7 <== standard form

The graph is of y = f(x) is shown below. What are all of the real solutions of f(x) = 0?

Reika [66]

The real solutions of f(x) = 0 is; x = -8, 0 and 4

<h3>How to find the roots of a polynomial graph?</h3>

When talking about real solutions of a polynomial, we are simply referring to the values of x that make the polynomial f(x) = 0.

Now, in a polynomial graph as attached, the real solutions are the roots and they are the values of x where the curve crosses the x-axis.

From the given graph, the real solutions are at x = -8, 0 and 4

Thus, we conclude that the real solutions of f(x) = 0 is; x = -8, 0 and 4

Ede4ka [16]

Let x represent number of wrong questions answered by Aaron.

We have been given that Aaron is taking a multiple choice test with a total of 20 points available. Each question is worth exactly 1 point. We are asked to find Aaron's score (out of 20) if he got 6 questions wrong.

To find Aaron's score, we will subtract number of wrong answers from total score.

$\text{Aaron's score}=\text{Total score}-\text{Number of wrong answers}$

$\text{Aaron's score}=20-6$

$\text{Aaron's score}=14$

Therefore, Aaron's test scores would be 14 out of 20.

To find Aaron's score if he got x questions wrong, we will subtract x from total scores that is $20-x$ .

Therefore, Aaron's score would be $20-x$ , if he got x questions wrong.

A sample was taken of the salaries of four employees from a large company. the following are their salaries, in thousands of dol

Free_Kalibri [48]

For given sample of salaries of four employees, the variance of their salaries is: 26 thousands of dollars

The formula for the variance is,

$S^2=\frac{\sum (x_i - \bar{x})^2}{n-1}$

where,

$S^2$ = sample variance

$x_i$ = the value of the one observation

$\bar{x}$ = the mean value of all observations

n = the number of observations

For given question,

n = 4

First we find the mean of their salaries.

(33 + 31 + 24 + 36 ) / 4 = 31

So, $\bar{x}=31$

Using the formula for variance ,

$S^2=\frac{(33-31)^2}{4-1}+\frac{(31-31)^2}{4-1}+\frac{(24-31)^2}{4-1}+\frac{(36-31)^2}{4-1}\\\\ S^2=\frac{4}{3} + \frac{0}{3} + \frac{49}{3} + \frac{25}{3} \\\\S^2= \frac{4+49+25}{3}\\\\S^2=\frac{78}{3} \\\\S^2=26$

Therefore, for given sample of salaries of four employees, the variance of their salaries is: 26 thousands of dollars
