She will earn $920 after working 40 hours.
Step-by-step explanation:
Given,
Amount per hour = $20
Raise = 15%
Raise amount = 15% of Amount per hour
New amount per hour = Amount per hour + raise amount
New amount per hour = 20+3= $23
Total earning after working 40 hours = Amount per hour * 40
She will earn $920 after working 40 hours.

Given equation : y=ax^2
Taking a to the other side we have, x^2=(1/a)*y
This equation describes a parabola that opens up.
When a is negative, the focus is on the negative y-axis, therefore, the parabola opens down.
The answer is a. down.
Slope-intercept form of a line:
y=mx+b
m=slope
b=y-intercpet
Data:
m=5
b=8
the equation of the line will be:
y=5x+8
Answer: y=5x+8
For X the answer would be..
Now for Y the answer would be..
Answer:
300 miles
Step-by-step explanation:
The distance equation is D = RT
Where
D is the distance
R is the rate
T is the time
<u>Mindy</u>
8 am to 1 pm = 5 hours
<u>Kelly</u>
8 am to 2 pm = 6 hours
Kelly's rate is 10 mph SLOWER than mindy, so if we let Mindy's rate be "m", so Kelly's rate will be " m - 10 "
Now using the distance equation, we can write:
Mindy >>> D = RT >>> D = 5m
Kelly >>> D = RT >>> D = 6(m-10) >>> D = 6m - 60
Since both the distances are equal, we can write:
5m = 6m - 60
m = 60
We want the distance, we know:
D = 5m
D = 5(60)
D = 300 miles
The distance is 300 miles
