Replace x with 8 in the equation of y = (3/4)x + 7
y = (3/4)(8) + 7
y = 6 + 7
y = 13
Write 1 16/17 as a common fraction: 33/17
16 ÷ 33/17
To divide by a fraction, multiply by the reciprocal:
16 x 17/33 = 272/33 = 8 8/33
The vertex will represent the highest point of the arc; the point where it is no longer going upward and is beginning to fall downward.
The x-value will be the horizontal distance from the cannon; the y-value will be the height.
y = k·x
1 = k·-3
Divide by -3:
k = -1/3 <--- the constant of variation
The revised formula:
y = (-1/3)·x
When y = 4:
4 = (-1/3)·x
Multiply by -3:
-12 = x
A direct variation has this form: y = kx, where x is the constant of variation.
To solve this, you need a set of values -- what x = when y =-3.
Can you post that value?
Since 1 foot = 12 inches
Then (1 foot)² = (12 inches)² = 144 in²
to convert 235 ft² multiply by 144 in²/ft² to get 33,840 in²

2/5 ÷ 1/8
To divide fractions, multiply by teh reciprocal:
2/5 x 8/1 = 16/5
-7 - (10q + 3)
Distribute the minus sign:
-7 - 10q - 3
Combine -7 and -3:
-10 - 10q
