Contains the origin and is parallel to the line 8x − 3y = 3
Licemer1 [7]

Answer:

y=(8/3)x

Step-by-step explanation:

First, we make 8x-3y=3 into the form y=mx+b

3y=8x-3

y=(8/3)x-1

For an equation to be parallel to this equation, the slope must be the same, so the new equation will be:

y=(8/3)x+b

We know that (0,0) is a point in this line. We plug (0,0) into the equation to find b:

0=(8/3)*0+b

b=0

y=(8/3)x

There were 100 questions on a math test. If Jamal got 4 times as many right as he got wrong, what was Jamals score?
IgorLugansk [536]

Jamal's score is 80

<u>Explanation:</u>

Given:

Number of questions = 100

Let w be the number of wrong answers

Let r be the number of right answers

According to question,

r = 4w

r + w = 100

Solving both the equations we get:

4w + w = 100

5w = 100

w = 20

If w = 20 then r = 4 X 20 = 80

Therefore, Jamal's score is 80

Find the value of n so that the line perpendicular to y = (-1/3)X-4 passes through the points (n. 6) and (4,15).
iogann1982 [59]

Answer:

1

Step-by-step explanation:

The slope of the perpendicular is the negative inverse of the slope of the line.

m = -1 / (-⅓)

m = 3

The slope between the two points is 3, so:

3 = (15 − 6) / (4 − n)

3 (4 − n) = 9

4 − n = 3

n = 1
