Answer:
x = 81
Steps:
It says that y ~ √x
We have points (9, 18) as a guide.
We can write y = f(x) = a√x +b
Use points (9, 18) as a guide
18 = a√9 +b
18 = 3a + b
One solution might be a = 6, which means f(x) = 6√x
Thus when y = 54,
54 = 6√x
9 = √x
81 = x
Answer:
y= b+ 3a
Step-by-step explanation:
Given data
We are required to rent a bike and a helmet
le the flat fee for bike rental be a
and the flat fee helmet be b
let the number of hours be h
and let the total cost be y
So
y= b+ah
for h = 3
tThen the expression for the total is given as
By cross-multiplying, we get
15x + 30 = 24
15x = -6
x = -3 / 5
5600*.065=364 5600+364=$5964 in the account at the end of the year. ☺☺☺☺<span>
