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

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
Write the equation in slope-intercept form y+3=4(x−1) plz do step by step
Answer:y=4x -7

Answer:
£ 2.38
Step-by-step explanation:
Cost of 2.5 kg potatoes = £ 1.40
Cost of 1 kg potatoes = [tex]\frac{1.40}{2.5}\\[/tex]
Cost of 4.25 kg potatoes = [tex]\frac{1.40}{2.5}*4.25\\\\[/tex]
= 1.40 * 1.7

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
hope this helps!! tell me if it doesnt make sense and i can help you!! also if it is right can i have brainliest :) no worries though happy to help

What is the solution for -3x ≥ 36?
Answer:
x ≤ -12
General Formulas and Concepts:
Pre-Algebra
Equality PropertiesStep-by-step explanation:
Step 1: Define inequality
-3x ≥ 36
Step 2: Solve for x
Divide both sides by -3: x ≤ -12Here we see that any number smaller than or equal to -12 would work as a solution.
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
