Answer:
I think it's measure of distance.
let me know if that is right
Part A. Yes, because y=f(x)=x⁵.
Part B. f(4)=2(4)+12=8+12=20.
X + y = 9 Subtract x from both sides.
y = 9 - x
x^2 + y^2 = 53
x^2 + (9 - x)^2 = 53 Remove the brackets.
x^2 + 81 - 18x + x^2 = 53 Collect the like terms on the left.
2x^2 - 18x + 81 = 53 Subtract 53 from both sides.
2x^2 - 18x + 81 - 53 = 0
2x^2 - 18x + 28 = 0 This factors, but you can see it much easier if you pull out 2 as a common factor.
2(x^2 - 9x + 14) = 0
2(x - 2)(x - 7) =0 You could divide by 2 on both sides. But you can also leave it.
x - 2 = 0
x = 2
x - 7 = 0
x = 7
If x = 2 then y = 7
If x = 7 then y = 2
1,000 words
10^4=10,000
10^3=1,000
First make an equation then solve for the variable.
8,800 is the end goal so that is what it is going to equal
Since his parents are contribuating 6,000 we can add that as a constant
Now it says in 2 years but it askes us in months so we times 2 by 12 to get 24 months he will be saving.
Now it is asking us how much he should save per month be we don't know that so that is our variable.
8,800 = 24x + 6,000
Solve
8,800 - 6,000 = 24x
2800/24 = x
116.67 = x (rounded for currency)
Sean would have to save $116.67 a month in order to pay for the community college
