Answer: it is 15
Step-by-step explanation:
I think it slopeeeeeeeeeeeeeeeeeeee
4x=-3y+17 becomes 4x+3y=17
4x+3y=17
3x-4y=-6
alrighty
elimination
muliply first equation by 4 and 2nd by 3 and add them
16x+12y=68
9x-12y=-18
add them
25x+0y=50
25x=50
idivide both sides by 25
x=2
sub back
3x-4y=-6
3(2)-4y=-6
6-4y=-6
-4y=-12
y=3
(x,y)
(2,3)
After 1 year, the initial investment increases by 7%, i.e. multiplied by 1.07. So after 1 year the investment has a value of $800 × 1.07 = $856.
After another year, that amount increases again by 7% to $856 × 1.07 = $915.92.
And so on. After t years, the investment would have a value of
.
We want the find the number of years n such that

Solve for n :





Answer:
x=11
Step-by-step explanation:
Notice that the first diagram is similar with the second diagram with ratio 1:2
Ex: Side length of JK is 6 and NP being 12, 6:12→1:2
You can conclude that x:22 needs to follow the ratio of 1:2
Thus, x=11
