The answer is x=42.8+- (plus or minus) 12
So he should either have $30.80 or $44.80 left
Answer:
the truck will over load with 13 refrigerators and 8 pianos
Step-by-step explanation:
13 refrigerators is 2600 lbs
8 pianos is 4200 lbs
both added together is 6800 lbs
the truck can only hold 5900 so 13 refrigerators and 8 pianos is too heavy

Answer: y = 1.2</h3>
Work Shown:
Inverse variation equations can be written in the form x*y = k for some fixed number k. Let's plug in the first point (x,y) = (1.6, 6) to compute the value of k
x*y = k
1.6*6 = k
9.6 = k
k = 9.6
Therefore the equation updates to
x*y = 9.6
Plug in x = 8 and solve for y
x*y = 9.6
8*y = 9.6
y = 9.6/8 .... divide both sides by 8
y = 1.2
