0 hours-
Jordan: 10
Jake: 15

1-
19
21.50

2-
28
28

They will have made the same amount of money after they have completed 2 hours of work each.

--------------------------

Another easy way to find the answer is to put the two into expressions and combine into an equation:

Jordan: 9x+10
Jake: 6.5x+15

Put into one equation:
9x+10=6.5x+15

Solve:

9x+10=6.5x+15

Step 1) Subtract 6.5x from both sides:

2.5x+10=15

Step 2) Subtract 10 from both sides:

2.5x=5

Step 3) Divide by 2.5 on both sides:

x=2

Step 4) Your answer:

You get the same 2 (hours)

If you need the value (Like how much money they made) then just plug in your x value to both expressions.

9x+10=
18+10=
28

6.5x+15=
13+15=
28

Find two complex numbers that have a sum of i10 a different of -4and a product of -29​
lianna [129]
<h2>-2+5i and 2+5i</h2>

Step-by-step explanation:

   Let the complex numbers be a+ib\textrm{ and }c+id.

Given, sum is 10i, difference is -4 and product is -29.

(a+c)+i(b+d)=10i ⇒ a+c=0,b+d=10

(a-c)+i(b-d)=-4 ⇒ a-c=-4,b-d=0

a=-2,c=2,b=5,d=5

(a+ib)(c+id)=(-2+5i)(2+5i)=-4-25=-29

Hence, all three equations are consistent yielding the complex numbers -2+5i\textrm{ and }2+5i.

Use the number line below, where RS = 8y +4, ST = 4y + 7, and RT = 107.
NISA [10]

Answer:

a) Finding value of y:

8y+4+4y+7=107

12y+11=107

12y =107-11

12y =96

y = 96/12

y = 8

b) RS= 8y+4

= 8(8)+4

= 64+4

= 68

ST= 4y+7

= 4(8)+7

= 32+7

= 39

What is X-3y=9 in slope intercept form and the equation
ivann1987 [24]
The slope intercept form would be y= 1/3x -3
First, you add 3y to each side
That cancels out the -3y on the left side of the equation and adds a +3y to the right
Now you have x = 3y + 9
Subtract 9 from each side and now you have
3y = x - 9
Now all you have to do is divide 3 from each side
3y divided by 3 = y
x divided by 3 = x/3 or 1/3 x
-9 divided by 3 = -3

The end result is y = 1/3x - 3
