X-5y=17 then x = 5y + 17
replace x = 5y + 17 into <span>-4x+y=8
</span>-4(5y + 17) +y = 8
-20y - 68 + y = 8
-19y = 8 + 68
-19y = 76
y = 76/-19
y = -4
x = 5y + 17
x = 5(-4) + 17
x = -20 + 17
x = 3
Answer: the order pair (3, -4)
Basically what is happening is:
You start out with 15. That 1st week you have 22% more than 15, or in other words 15*1.22. The following week you have 22% more than 22% more of 15, which is 15*1.22*1.22.
Now we can write a function that models this situation:
f(n): number of views
n: number of weeks since you started
f(n) = 15(1.22^n)
We want to find out how many views there are after four weeks, so plug 4 in for n.
f(4) = 15(1.22^4)
f(4) = 33.23
This means after 4 weeks you can expect the video to have 33 views.
Answer: Interest will be 3%
Step-by-step explanation:
4.5x = x * r * 13.5
4.5x = 13.5x*r
r = 13.5x/4.5x = 3%
