Answer:
12 hours
Step-by-step explanation:
Step one:
given data
base fee= $60
charge per hour= $15
let the number of hours the plumber work be x
the linear function for the charge is the equation of line.
that is y=mx+c
Step two:
given that y=$240
240=15x+60
240-60=15x
180=15x
divide both sides by 15 we have
x=180/15
x=12
<u>The number of hours is 12</u>
The given expression is
-2x² + 17 - 15x + 7xy
The algebraic expression may be written as
-2x² + 7xy - 15x + 17
The constant term does not contain either x or y.
Therefore 17 is the constant term.
Answer: 17
I think it would be 19 because if you take 100-5 it would be 95 and divide 95 by 19 you would get 5 so each student got 5 cookies and there was 19 students
Since I just realized that you meant x^2-2x+1, let me evaluate this step by step:
x^2-2x+1
((-3)^2)-(2(-3))+1
9-(-6)+1
9+6+1
16
Therefore, that would equal 16.
