Answer:

Step-by-step explanation:

Their earnings would be the same after 4 hours
Let the number of hours be x, and the weekly earning be y
So, the given parameters are:
<u>Kimi</u>
- Earnings = $9 per hour
- Weekly allowance = $8
So, the equation for Kimi's weekly earning is:

<u />
<u>Jordan</u>
- Earnings = $7 per hour
- Weekly allowance = $16
So, the equation for Jordan's weekly earning is:

Equate both equations

Collect like terms


Divide both sides by 2

Answer:
$1,140, or $1,144.9
Step-by-step explanation:
70 is 7% of 1,000

Or, if you mean 7% compounded annually then....
1,070 after first year.
7% of 1,070 = 74.9
74.9 + 1,070 = 1,144.9

Answer:
<u>y = -3x + 8</u>
Step-by-step explanation:
<u>Given :-</u>
Point on line = (5, -7)
Slope (m) = -3
<u>To find :-</u>
Equation of line
<u>Solving :-</u>
Using point-slope form of equation,
y - y₁ = m(x - x₁)
y + 7 = -3(x - 5)
y + 7 = -3x + 15
<u>Solution :-</u>
<u>y = -3x + 8</u>
