I’m pretty sure it’s true. :)
Answer:
Step-by-step explanation:
Equation
-5(-3x+1)=-45 If this is not correct, leave a comment please.
Solution
-5(-3x+1)=-45 Divide by -5
-5(-3x + 1)/5 = -45/-5
(-3x + 1) = 9 Remove the brackets
-3x + 1 = 9 Subtract 1 from both sides
-3x + 1 - 1 = 9 - 1 Simplify
-3x = 8 Divide by -3
-3x/-3 = 8/-3
x = -8/3
or
x = -2.66
or
x = - 2 2/3
Answer:
140 miles
Step-by-step explanation:
Let
Number of miles = m
Total cost = fixed cost + variable cost
Company A = $150 + $0.40m
Company B = $80 + $0.90m
Equate company A and company B equation
Company A = Company B
$150 + $0.40m = $80 + $0.90m
Collect like terms
150 - 80 = 0.90m - 0.40m
70 = 0.50m
m = 70 / 0.50
= 140
m = 140 miles
The number of miles in a day at which the rental costs for Company A and Company B are the same is 140 miles
That is false.
y=7 is just a simplified way of writing y = 0 x 1 + 7
