Answer:

\large\boxed{j=-\dfrac{3}{2}\to j=-1\dfrac{1}{2}\to j=-1.5}

Step-by-step explanation:

12.6j+8=10.2j+4.4\qquad\text{subtract 8 from both sides}\\\\12.6j+8-8=10.2j+4.4-8\\\\12.6j=10.2j-3.6\qquad\text{subtract}\ 10.2j\ \text{from both sides}\\\\12.6j-10.2j=10.2j-10.2j-3.6\\\\2.4j=-3.6\qquad\text{divide both sides by 2.4}\\\\\dfrac{2.4j}{2.4}=\dfrac{-3.6}{2.4}\\\\j=-\dfrac{3.6\cdot10}{2.4\cdot10}\\\\j=-\dfrac{36}{24}\\\\j=-\dfrac{36:12}{24:12}\\\\j=-\dfrac{3}{2}\to j=-1\dfrac{1}{2}\to j=-1.5

The equation of the line that is parallel to the given line and has an x-intercept of 3 is y = 2/3x - 2

<h3>What is the equation of the line that is parallel to the given line and has an x-intercept of 3?</h3>

The given parameters are

Point =(0, -1) and (3, 1)

Calculate the slope using

m = (y₂ - y₁)/(x₂ - x₁)

Where m represents the slope

So, we have:

m = (1 -- 1)/(3 -0)

Evaluate

m = 2/3

Parallel lines have equal slopes

So, the slope of the other line is

m = 2/3

Linear equations are represented as:

y = mx + c

Where m represents the slope and c represents the y-intercept

So, we have

y = 2/3x + c

An x-intercept of 3 means

0 = 2/3 * 3 + c

So, we have

c = -2

Substitute c = -2 in y = 2/3x + c

y = 2/3x - 2

Hence, the equation of the line that is parallel to the given line and has an x-intercept of 3 is y = 2/3x - 2

miskamm [114]

Answer:

Step-by-step explanation:

2p/2 = 2x+7

1) 2x+7 -x - 5 =

width = x + 2

2) 2p/2 = 21 in

x + 5 + x + 2 = 21

2x = 14

x = 7

lenght = 7 + 5 = 12 in

width = 7 + 2 = 9 in

3 )

A = (x+5)(x+2)

4)

A = 12 x 9 = 108

1.<br> Slope = (7,-1) and 12,-2)
Evgen [1.6K]

Answer: -1/5

Step-by-step explanation:

the equation to solve slope with two points is the y coordinate in the second point minus the y coordinate in the first point over the x coordinate in the second point minus the x coordinate in the first point so this one would be

(-2 - -1)/(12-7)

On the top you subtract a negative it becomes a positive and you get -1/5
