Answer: 36.66min
Step-by-step explanation:
y = 47.38 + 0.617x
where y is the number of dollars
x is the number of minutes on the job
Given a value of y = $70, then
We substitute y = $70 in the equation.
70 = 47.38 + 0.617x
22.62 = 0.617x
X = 22.62/0.617 = 36.66min
3.48 x 10^ -5
move the decimal point back to the first number that isn't zero, if the decimal is moved right 5 spaces, it will be 10^ -5 , if a number has a zero, such as 0.000104, it would be 1.04 x 10^ -4.
Slope = -1/4
(4, 7)
y - 7 = -1/4 (x - 4)
y - 7 = -1/4x + 1
y = -1/4 + 8
answer is C
I just had the question and the correct answer is 36.
