Answer:

y = x - 3

Step-by-step explanation:

Because as x increases by 1 y increases by 1, so y = x ,

but the y intercept is - 3

Given that y varies directly as x and inversely 2m-1 and that y=5 when x-7 and m=4 .

Sergeu [11.5K]

Answer:

Step-by-step explanation:

y ∞ x/m

y = kx/m

Where k is the constant of proportionality

A. k = ym/x

y=5 when x=7 and m=4

k = (5×4)/7

k = 20/7

y = 20x/7m

B)the value of when x=2and m=2

y = 20x/7m

y = (20×2)/(7×2)

y = 40/14

y = 20/7

y = 2 6/7

C. The value of m when y=2 and x=4

y = 20x/7m

7ym = 20x

m = 20x/7y

m = (20×4)/(7×2)

m = 80/14

m = 40/7

m = 5 5/7

A line is graphed below. Write an equation in the form y = mx + b that represents this line

galben [10]

<h3>Explanation</h3>

Slope-Intercept form

$y = mx + b \\ m = slope \\ b = y - intercept$

Calculate the slope with two given coordinate by using rise over run.

$\begin{cases}(x_1,y_1) = ( - 4,0) \\ (x_2,y_2) = ( 0,2) \end{cases}$

These two coordinate points are part of the graph and can be used to find the slope.

$m = \frac{y_2 -y_1 }{x_2 - x_1}$

Substitute the coordinate points in the formula.

$m = \frac{2 - 0}{0 - ( - 4)} \\ m = \frac{2}{ 4} \\ m = \frac{1}{2}$

Therefore, the slope is 2.

Rewrite the equation in slope-intercept.

$y = \frac{1}{2} x + b$

Calculate the y-intercept by substituting any given points in new rewritten equation.

$(x,y) = ( 0,2)$

I will be substituting these coordinate points in the equation.

$y = \frac{1}{2} x + b$

Substitute x = 0 and y = 5 in the equation.

$2 = \frac{1}{2} (0) + b \\ 2 = 0 + b \\ 2 = b$

Therefore the y-intercept is (0,2).

Rewrite the equation.

$y = \frac{1}{2} x + 2$

<h3>Answer</h3>

 $\large \boxed{y = \frac{1}{2} x + 2}$

Solve the equation 3(2x + 2) = 3x − 15.

Margaret [11]

Hi there! :)

Answer:

x = -7.

Step-by-step explanation:

Starting with:

3(2x + 2) = 3x - 15

Begin by distributing '3' with the terms inside of the parenthesis:

3(2x) + 3(2) = 3x - 15

Simplify:

6x + 6 = 3x - 15

Isolate the variable by subtracting '3x' from both sides:

6x - 3x + 6 = 3x - 3x - 15

3x + 6 = -15

Subtract 6 from both sides:

3x + 6 - 6 = -15 - 6

3x = -21

Divide both sides by 3:

3x/3 = -21/3

x = -7.
