Larger is x
the other is called y
sum of squares is 394
x^2+y^2=394
one is 2 less that other
x>y so
y+2=x
subsitute y+2 for x
(y+2)^2+y^2=394
expand
y^2+4y+4+y^2=394
add like terms
2y^2+4y+4=394
divideboth sides by 2
y^2+2y+2=197
subtract 197 from both sides
y^2+2y-195=0
factor
(y+15)(y-13)=0
set each to zero
y+15=0
y=-15
impossible since it is stated that they are positive so get rid of this solution
y-13=0
y=13
find other
y+2=x
13+2=x
15=x
numbers are 13 and 15
Y is 15 :)
Explanation:
If you divide 3/2, you get 1.5. 15/10 is also get 1.5
Another way of doing this is by cross multiplying. Multiply 3 by 10 to get 30 on the right side of the equation. Multiply 2 by y to get 2y. Then divide both sides by 2 and you get y = 15.
We start off with 100 dollars. Which in this case Eliza deposits 25 every month.
What is average rate of change?
It is a measure of how much the function changed per unit, on average, over that interval
So this meaning that
25x + 100 would be are main focus here.
Replace x with 2 since we are finding the change of the 2nd account
25(2) + 100 = 150
Do the same problem but replace x with 10
25(10) + 100 = 350 dollars
So the average rate of change would be 25 dollars
