"a rise of a quarter from last year" means the percentage went up by 25%
x = old value
x + 25% of x = x + 0.25x = 1.25x = new value = 0.25 since "1 in 4" means 1/4 = 0.25
So,
1.25x = 0.25
x = 0.25/1.25
x = 0.2
x = 2/10
x = 1/5
Answer: The fraction of families that owed money is 1/5, or 1 in 5.
The given is f(x) = 620 · 7.8x
The standard equation for an exponential function is f(x) = Aoe^bx
where:
A is the initial amount
b is the growth factor which is constant
x is any real number
Therefore, the initial amount is 620 and the growth factor is 7.8
Answer:
x < -7
Step-by-step explanation:
3x < -21
<u>Step 1: Divide both sides by 3</u>
3x < -21
3x / 3 < -21 / 3
x < -7
Answer: x < -7
