Hi again!

Come on, you got this!

2x + 6 - 6x =30

All you have to do is put the ones alike together

2x - 6x + 6 = 30

-4x + 6 = 30

Transfer 6 to the right side(don't forget to change the sign)

-4x = 30 - 6

-4x = 24

x = 24/-4

x = -6

The correct answer is option A

What is the slope of the line that passes through the points (-6, 8)(−6,8) and (-16, 33) ?(−16,33)? Write your answer in simples
Taya2010 [7]

Given:

A line passes through the points (-6, 8) and (-16, 33).

To find:

The slope of the line.

Solution:

If a line passes through two points, then the slope of the line is

m=\dfrac{y_2-y_1}{x_2-x_1}

The line passes through the points (-6, 8) and (-16, 33). Using the above formula, the slope of the line is

m=\dfrac{33-8}{-16-(-6)}

m=\dfrac{25}{-16+6}

m=\dfrac{25}{-10}

m=-2.5

Therefore, the slope of the line is -2.5.

Find the probability of 3 successes in 7 trials of a binomial experiment in which the probability of success in any one trial is
natita [175]

Answer: 0.07

Step-by-step explanation: Since it is a binomial experiment , we will use the formula:

n C r p^{r}q^{n-r}

p = 0.35

q = 1 - 0.35 = 0.65

n is the number of trials = 7

r = 3

substituting into the formula, we have

7 C 3 (0.35^{3}0.65^{7}

= 35(0.35^{3}0.65^{7}

=0.0736

to the nearest tenth

= 0.07
