Answer:
5x = 14
Step-by-step explanation:
If 5 yards of fabric is $14 you need an equation that would solve how much 1 yard of fabric costs. You can say 5x = 14 or x = 2.8 which means that one yard of fabric (1x or just x) is $2.80.
Answer:
the answer would be f(x)=x-3
Step-by-step explanation:
Answer:
4949/200=
Step-by-step explanation:
You haven't provided any value, but I can tell you the solution set for the inequality.
First of all, expand both sides:
Add 3x to both sides:
Add 6 to both sides:
Which is of course equivalent to
Divide both sides by 9
So, every number smaller than 2 is part of the solution of this inequality.
Answer:
a) 46.98%
b) increasing rate of change
Step-by-step explanation:
In year 1987, investment worth $29800
In year 1997, investment worth $43800
Rate of change = 1997investment - 1987investment / 1987investment × 100
Rate of change = 43800 - 29800/29800 × 100
= 14000/29800 × 100
= 0.46979 × 100
= 46.98%
Therefore, the rate of change of the investment during the time period is 46.98%.
b) The rate of change of the investment is increasing. This is as a result of the following reasons. First, the value of rate of change is positive. Second, there is no value for rate of change for period before the time period so we cannot compare rate of change.
