Answer:
Step-by-step explanation:
Let
- y- the amount of charge,
- x - the number of miles
The equations as per question are below
<u>Crazy Curly's</u>
<u>Bill's Beauties</u>
Solve the system by substitution
- 0.3x + 20 = 0.2x + 50
- 0.3x - 0.2x = 50 - 20
- 0.1x = 30
- x = 30/0.1
- x = 300
We can use the equation [ f(x) = 16*4^(x-1) ] where x equals the year of study.
f(7) = 16*4(7-1)
f(7) = 16*4^6
f(7) = 16*4096
f(7) = 65,536
There is no option that resembles the correct answer.
Best of Luck!
Answer:
y = 2
Step-by-step explanation:
from the question which says that y is directly proportional to the positive square root of x can be expressed mathematically by saying
y ∝ √x
y = k√x..................................................... where k is the constant of proportionality.
y = 12, x = 9 , k = ?
from
y = k√x
12 = k√9
12 =3k
divide both sides by the coefficient of k which is 3
12/3 = 3k/3
4 = k
therefore K = 3
now, to find the value of y when x = 1/4
from y = k√x
y = 4√1/4
y = 4 × 1/2
y = 2
therefore the value of y when x = 1/4 in this expression y = k√x is 2
