One electrician charges a $50 service call fee plus $25 per hour for labor. Another electrician charges a $35 service call fee plus $27.50 per
hour for labor. How long would a job take if the total cost for each electrician is the same?
A.5 hours
B.6hours
C.7 hours
D.8 hours
Answer:
c. 6 hour
Step-by-step explanation:
time = t
25t + 50 = 27.50t + 35
solve for t : 25t + 50 = 27.5t +35
27.5t + 35 = (55t) /2 + 35 : 25t + 50 = (55t) /2 + 35
subtract (55t) /2 + 50 from bot side : -(5t) /2 = -15
multiply both side by -2/5: t = 6 hours
What is the zero of the equation -4x -12y = 32?
PLEASE HELP!!!!
Answer:
x = - 8
Step-by-step explanation:
To find the zero, let y = 0 in the equation and solve for x
- 4x - 12(0) = 32 , that is
- 4x = 32 ( divide both sides by - 4 )
x = - 8

WORTH 50 POINTS NEED HELP ASAP
Answer:
-10, -1, 5
Step-by-step explanation:
To find the zeros of a function, you have to set each factor to zero in equations, then solve for x ....
x + 10 = 0 ... then factor 10 over (subtract 10 from each side) ...
x = -10
x-5=0
then repeat (add 5 to both sides) (and subtract 1 from both sides) ...
x -5 = 0 to x = 5
x + 1 = 0 to x = -1

A moving company’s moving rates can be represented by the function f(x) = 3x + 400, where x is the number of miles for the move.
Another moving company’s rates can be represented by the function g(x) = 5x + 200.
Which function represents the difference between the moving companies' rates, h(x) = f(x) – g(x)?
A) h(x) = 2x + 200
B) h(x) = –2x + 200
C) h(x) = 5x – 200
D) h(x) = 5x + 600
Answer:
B) h(x) = –2x + 200
Step-by-step explanation:
f(x) = 3x + 400
g(x) = 5x + 200
f(x) - g(x) = 3x + 400 - (5x + 200) = -2x + 200

Write the equation in slope-intercept form y+3=4(x−1) plz do step by step
Answer:y=4x -7
Step-by-step explanation:
The slope intercept form is: y= mx + b
Y+3 = 4(x-1) step one distribute 4
Y+3= 4x - 4 step two subtract 3 from both sides
Y=4x -7
