-4 is the x intercept.as in the values on the x-axis
It increased by $3.15
The new monthly cost is $48.15
(3m - 4n - 7) - (8m + n - 6)
3m - 8m = - 5m
-4n - n = -5n
-7 - (-6) = -7 + 6 = -1
-5m - 5n - 1 is your answer
hope this helps
Answer:
The answer will be 7(2x - 1)
Step-by-step explanation:
1) Convert 7 and 1/2 to improper fraction. Use this rule: a b/c = ac + b/c

2) Simplify 7 × 2 to 14 .

3) Simplify 14 + 1 to 15.

4) Collect like terms.

5) simplify.

6) Factor out the common term 7.

Therefor, the answer is 7( 2x - 1 ).
Answer:
y = 
Step-by-step explanation:
Given y varies directly with x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition y = 5 when x = 6
k =
= 
y =
x ← equation of variation
When x = 5, then
y =
× 5 =
