Answer:
Parallel line, [tex]y=\frac{3x}{2} -\frac{5}{2}[/tex]
Perpendicular line, [tex]y=4-\frac{2x}{3}[/tex]
Step-by-step explanation:
For the parallel line, In the equation y=mx+c, we are trying to find c.
We know that m=[tex]\frac{3}{2}[/tex], so
we have the equation y=[tex]\frac{3x}{2} +c[/tex]
So we substitute the points we are given (3,2) into
[tex]2=\frac{3}{2}*3+c\\Thus, c= \frac{-5}{2}[/tex]
The final equation we get is
[tex]y=\frac{3x}{2} -\frac{5}{2}[/tex]
For the perpendicular line, we need to find the inverse of the slope.
The inverse of the slope [tex]\frac{3}{2} = -\frac{2}{3}[/tex]
So, we use this in our formula and also plug in the same coordinates we were given.
Therefore, we get:
[tex]2= -\frac{2}{3}*3+a\\a=4\\\\y=4-\frac{2x}{3}[/tex]

Janet worked 3 hours more than David and 7 hours less than Kate. David earned $7.50 per hour, Janet earned $6 per hour, and Kate earned $9 per hour. If Kate earned $27 more than David and Janet combined, how much did each person earn?
We want to write and solve a system of equations to see how much each person earns.
What each one earned is:
Janet = $78Kate = $180David = $75Let's define:
J = number of hours that Janet worked.D = number of hours that David worked.K = number of hours that Kate worked.The information is:
"Janet worked 3 hours more than David and 7 hours less than Kate"
From this we can write:
J = D + 3
J = K - 7
We know that:
David earned $7.50 per hour.Janet earned $6 per hour.Kate earned $9 per hour.Finally, we know that Kate earned $27 more than David an Janet combined, then we can write:
$9*K = $27 + ($7.50)*D + $6*J
Then we have a system of equations:
J = D + 3
J = K - 7
$9*K = $27 + ($7.50)*D + $6*J
We can rewrite the first and second equations to get:
D = J - 3
K = J + 7
Now we can replace these two in the other equation to get:
$9*(J + 7) = $27 + ($7.50)*(J - 3)+ $6*J
Now we can solve this for J:
$9*J + $63 = $27 + $7.50*J - $22.50 + $6*J
$9*J - $7.50*J - $6*J = $27 - $63 - $22.50
-$4.50*J = -$58.60
J = (-$58.60)/(-$4.50) = 13
This means that Janet worked for 13 hours.
And with:
K = J + 7 = 13 + 7 = 20
D = J - 3 = 13 - 3 = 10
We can see that Kate worked for 20 hours and David for 10 hours.
Then each one of them earned:
Janet = 13*$6 = $78
Kate = 20*$9 = $180
David = 10*$7.50 = $75

Find an equation perpendicular to y = 5 and passing through (-1,2).
Answer:
x=-1
Step-by-step explanation:
A line perpendicular to y=5 is a vertical line
y =5 is a horiztonal line so perpendicular line is x= constant
The x value of (-1,2) is x = -1
So the line is x=-1

Step-by-step explanation:
If you use scientific notation,
move the decimal 7 places to the right to find a whole number between 1 and 9.
then, count the number of spaces.
in this instance, since the original number was a decimal, you need to put a negative power of 10.

Solve the inequality.
7x - 1 <= 7
1. x <=-1
2. x <= 4
3. x <= 1
4. x>=-1
Answer:
I got x <= 8/7 which is none of the answer options given. Ask your professor about that.
Step-by-step explanation:
7x-1 <= 7
add 1 on each side
7x <= 8
Divide by 7 on both sides
7x/7 <= 8/7
Final answer
x <= 8/7
Answer:
Option #1, 3 and 4
Step-by-step explanation:
7x - 1 <= 7
Let's try them one by one:
1)
x <= -1
-7 - 1 = -8 is less than or equal to 7: True
There could be multiple answers, so let's do the other ones:
2)
x <= 4
28 - 1 = 27 <= 7: False
3)
x <= 1
7 - 1 = 6 <= 7: True
4)
x >= -1
-7 - 1 <= 7
-8 <= 7: True
Therefore, #1, 3, and 4 are correct.

Which line has a slope of 1, and which has a slope of 2?
Use a ruler to help you graph a line whose slope is 5. Label this line a.
Answer:
Line "L" has the slope of 1 and line "K" has the slope of 2.
In order to graph a line with the slope of [tex]\frac{1}{3}[/tex] think of the numerator as the "rise" (how much you move up/down on the y-intercept) and the denominator as the "run" (how much you move to the side on the x-intercept)
Step-by-step explanation:
A slope of "1" is simply [tex]\frac{1}{1}[/tex] so you rise up one and move to the right once. This clearly demonstrated on line "L".
A slope of "2" is [tex]\frac{2}{1}[/tex] so you rise up two and move to the right once, as is demonstrated on line "K".
For the 2nd question, line "A" will have a slope of [tex]\frac{1}{3}[/tex] therefore it will move up once and then to the side three times. It will look like the image attached to this answer.
I hope this helped! Feel free to ask questions if needed!
