How do I find the value of x so the slope of a line through (x,5) and (4,2) is 1/3?

1 answer:

8 0

Slope=change in y/change in x
1/3 = 5-2/x-4 (or 2-5/4-x)
1/3 = 3/x-4
then cross multiply
1(x-4) = 3(3)
x-4=9
add 4 to both sides
x=13

Well, let us solve this step by step.

We know that Michelle earns 349 plus 3% of the Purchase price. Let us call the Purchase price as P, so that:

Earnings, E = 349 + 0.03 P

So if she earns 8,965 (E = 8,965) so we can find P:

8,965 = 349 + 0.03 P

0.03 P = 8,616

P = $287,200

Hello there!

To find this, we must simplify this equation.

first, let's simplify the right side

-1 * x = -x

-1 * 5 = -5

Now, we have: y -3 = -x -5

Now we must add + 3 to each side to get rif of the negative three

now we have y = -x - 2

So, your answer is B.) y= -1x - 2

I hope my answer was of assistance!

8. You are paid a commission plus $5.40 per hour with time and a half overtime

Elanso [62]

Answer:

$491.65

Step-by-step explanation:

The pay for the first 8 hours is $5.40 per hour × 8 hours = $43.20. Hours over 8 are paid at 1.5 × $5.40 = $8.10 per hour. There are at least 8 hours every day for the 6-day week. There are hours over 8 on Monday, Wednesday, Thursday, and Friday totaling 7 hours of overtime.

The amount of sales is more than $3000, so 4% will be paid on $3000, and 5% will be paid on the $1115 in excess of $3000.

So, the gross pay is ...

$43.20 × 6 + 8.10 × 7 = $315.90 . . . . wages

$3000 × .04 +1115 × .05 = $175.75 . . . commission

$315.90 +1.75.75 = $491.65 . . . . gross pay for the week
