27x - 8x
Step-by-step explanation:
3x³ - 2x² =
27x - 8x
Answer: {(1, 8.65), (2, 8.30), (3, 7.95)}
EXPLANATION
Given,
The watering can dispenses water at a rate of 0.35 gallon
per minute.
The original volume of water in the can was 9 gallons.
Therefore if,
y = the volume of water in the can in gallons
x = time in minutes
f(x) = y = 9 – 0.35x
When x = 1,
y = 9 – 0.35(1)
y = 9 – 0.35
y = 8.65
Therefore we have the pair (1, 8.65)
When x = 2,
y = 9 – 0.35(2)
y = 9 – 0.7
y = 8.3
Therefore we have the pair (2, 8.30)
When x = 3,
y = 9 – 0.35(3)
y = 9 – 1.05
y = 7.95
Therefore we have the pair (3, 7.95)
The set of ordered pairs shows the volume of water in the
can in gallons (y) as a function of time in minutes (x) from the first minute
after the can starts dispensing water is {(1, 8.65), (2, 8.30), (3, 7.95)}
The answer is 7.41717 x 10^4 because you move the decimal to the left 4 spaces
Pretty sure it's 8 3/4 ÷ 3 2/3.
Why?
So say you want to find the length of a rectangle who's area is 6, and the width is 2. You can divide the area by the width to find the length. 6/2 = 3.
Check: 2 * 3 = 6.
Back to the original question: 8 3/4 ÷ 3 2/3.
Improper fractions: 35/4 ÷ 11/3.
Switch division to multiplication and reciprocal: 35/4 * 3/11.
35/4 * 3/11 = 105/44.
Check:
105/44 * 11/3 = 1155/132 = 35/4 = 8 3/4
Length = 105/44
