Jamal is a door to door vacuum salesman. His weekly salary, S , is $250 plus $50 for each vacuum he sells. This can be written a

s S = 250 + 50 v , where v is the number of vacuums sold. If Jamal earns $1800 for a week's work, how many vacuums did he sell? If Jamal earns $1800 for a week's work, how many vacuums did he sell? If Jamal's pay was $1800 for the week, he sold vacuums.

Answer:

31 vacuums

Step-by-step explanation:

1800 = 250 + 50v

1800 - 250 = 50v

50v = 1550

v = 1550 / 50

v = 31

He sold 31 vacuums.

Select the correct answer Which equation represents a line that is perpendicular to line MN?
taurus [48]

Answer:

D. y = 4x - 6

Step-by-step explanation:

The equation that is perpendicular to the line MN should have a slope that when multiplied by the slope of line MN will result to negative one. Therefore,

Therefore,

m₁ × m₂ = -1

Using the 2 coordinates of MN let's find the slope,

(-7, 6)(5, 3)

Therefore,

m₁ = 3 - 6 / 5 - (-7) = -3 / 12 = - 1 / 4

The equation that represent a line perpendicular to the line MN is

y = 4x - 6 because the slope slope(m₂) is 4.

From our formula,

4 × - 1 / 4 = - 1

So, option D meets the requirement.

Seriously someone help me i answered it but i don’t know if it is right so please tell me if it is and how i got the answer or p
alex41 [277]

Answer:

<h2>C</h2>

Step-by-step explanation:

To determine a function rule, look at the table. Input the x and y value from one column into the function to see if it is correct.

<h3>Function a: y = 10 - 2x</h3>

Input values

22 = 10 - 2(6)

22 = 10 - 12

22 ≠ -2 ❌

As we can see, function a gives us a false statement, so a is incorrect.

<h3>Function b: y = 2 - 10x</h3>

Input values

22 = 2 - 10(6)

22 = 2 - 60

22 ≠ -58 ❌

We once again get a false answer, so b is also not correct.

<h3>Function c: y = 10 + 2x</h3>

Input values

22 = 10 + 2(6)

22 = 22 ✔

Finally, we get a true statement, so option c is correct.

<h3>Function d: y = 2 + 10x</h3>

Just to check that option c is correct, we need to prove that d is incorrect.

Input values

22 = 2 + 60

22 ≠ 62 ❌

This is also wrong, so that proves that c is correct.

I'm always happy to help :)
