B.) 15d+100
100 is a sure value as he earned it
We do not know how many days he worked, therefore variable d is used to represent d amount of days, but we do know he recieved $15 for everyday that he did work
Answer:
1200feet
Step-by-step explanation:
Given the the road's curve elevation modeled by the equation
y = 0.00005x^2 - 0.06x,
x is the horizontal distance in feet between the points where the road is at sea level and;
y is the elevation
The elevation the road is equal to sea level when y = 0
Substitute y = 0 into the equation and calculate x;
0 = 0.00005x^2 - 0.06x
0.06x = 0.00005x^2
0.06 = 0.00005x
x = 0.06/0.00005
x = 1200 ft
Hence they will place the stop sign at a horizontal distance of 1200feet
Answer:
x = 3
y = 8
Step-by-step explanation:
ok we will substitute
y = x + 5
into the second equation
4x + y = 20
4x + (x + 5) = 20
5x + 5 = 20
5x = 15
x = 3
y = x + 5 = 3 + 5 = 8
Answer: I think the length is 60.25 yd and the width is 19.75 yd
Step-by-step explanation: I formed a equation using the information that has been given.
Width : X
length : 1 + 3x
equation : (1 + 3x) + x = 80
Then, I added the like pairs ( 3x+x ). After, I subtracted 1 from 80 and got 79. Then I divided 79 and 4 (79/4) to get 19.75, which is my x value. later, I substituted the x value to the equation and received my answer.
