Top One
The equation for the top one looks like it is
y = (5/3) * x
So for example (5/3) 15 = 25 which is y is shown to be in the table of values.
Varies directly
Middle Table
Stupid as the question may seem, the answer is varies inversely. As the number of parachutes goes down the price per shute goes up. Maybe it does make sense.
Varies inversely.
Last Table
This one at least makes sense. As the cost of making the parachute goes up, so does the selling price.
Varies directly.
The correct answer is "<span>Step 2; 6x − 8 = 12 + 2x."
</span>
The step that the student first make an error is at the 2nd step. The correct step should be 6x − 8 = 12 + 2x.
Finishing the steps:
<span>Step 1: 2(3x − 4) = 8 + 2x + 4
</span>Step 2: <span>6x − 8 = 12 + 2x.
Step 3: 4x = 20
Step 4: x = 5</span>
So area=1/2 base times height
50=1/2 base times height
multiply both sides by 2
100=base times height
base=4height
100=4height times height
100=4height^2
divide 4
25=height^2
squarer root
5=height
subisute
base=4(5)
base=20
height=5
Two lines that meet to form congruent adjacent angles.
