Answer:

Hello...... here is a solution :

1 -  

Hello:

the   equation of "m" is : y = ax+b

the slope is a : a×(- 2/3) = -1......( perpendicular to a line : y=-2/3x+6 when the slope is -2/3 )

a = 3/2          

the line " n" that passes through (4, - 3) and  parallel to line "m" :  

when the slope is 3/2 ( same slope )

the equation in slope-intercept form of the line" n" is :

 y – (-3)= (3/2)(x – 4)

Answer: \bold{y=\dfrac{3}{2}x-9}

<u>Step-by-step explanation:</u>

Line m is perpendicular to y=-\dfrac{2}{3}x+6. Perpendicular means opposite and reciprocal slope, so

m=-\dfrac{2}{3}\ \quad m_\perp=\dfrac{3}{2}

Line n is parallel to Line m. Parallel means same slope, so m=\dfrac{3}{2}


Next, input the point (4, -3) and the slope \bigg(\dfrac{3}{2}\bigg) into the Point-Slope formula: y- y₁ = m(x - x₁)

y - (-3) = \dfrac{3}{2}(x-4)


Now, rewrite the equation in Slope-Intercept form - <em>distribute the slope and solve for "y".</em>

y + 3 = \dfrac{3}{2}x-\dfrac{3}{2}(4)

y + 3 = \dfrac{3}{2}x-6

   y = \dfrac{3}{2}x-9

WITH AN EQUATION
andrey2020 [161]

Answer:

x-35.75=40.00

Step-by-step explanation:

Let's use <em>m </em> as our variable.

So Marlen went to the mall and spent $35.75 on shoes. When she got home she had $40.00 in her purse.

An equation to represent this is : x-35.75=40.00

If you are interested in the value of x it is $75.75
