Answer:
Step-by-step explanation:
Given the equation y = 2,5x
y is the height of the water
x is the time.
To get the range of values of the height at t = 60s, we will substitute x = 60 into the function
y = 2.5(60)
y = 150 in
Hence the range of the situation is [0, 150].
The domain will be all positive integers i.e xEZ
Answer:
91.125 or 729/8
Step-by-step explanation:
take 4.5^3 to get 91.125
Y=2x-3 rise over run and then the y intercept
Answer:
Step-by-step explanation:
= x²(-3 +5) +y²(2 -3) +5xy -2y
= 2x² -y² +5xy -2y
a) there are 4 terms in the simplified expression
b) 2 terms have negative coefficients (-y² and -2y)
A ) y = 2(3) + 7
y = 15
b ) y = 2(-3) + 7
y = 1
