Use the table to write and solve an equation to find the number of

exis [7]

Answer:

$c = 11$

Step-by-step explanation:

Given

$Cars\ Sold:-: 8; 9; 12; c$

Required

What value of c makes the mean = 10

Mean is calculated as

$Mean = \frac{\sum x}{n}$

In this case;

Mean = 10 and n = 4;

So, we have:

$10 = \frac{8+ 9 + 12 + c}{4}$

$10 = \frac{29+ c}{4}$

Multiply both sides by 4

$10 * 4 = 29 + c$

$40 = 29 + c$

Solve for c

$c = 40 - 29$

$c = 11$

Write an equation in point slope form for the line with a slope of 3 passes through (1,2)

alexgriva [62]

Answer:

$y-2=3(x-1)$

Step-by-step explanation:

The point-slope form of a line is given as:

$y-y_1=m(x-x_1)$

Where

m is the slope

$x_1$ is the x-coordinate of the point given (passing through the line)

$y_1$ is the y-coordinate of the point given (passing through the line)

Now,

Given,

Slope = m = 3

$x_1$ = 1

$y_1$ = 2

Now, we simply plug these into the formula for point-slope form of a line:

$y-y_1=m(x-x_1)\\y-2=3(x-1)$

This is the point-slope form.
