<span>2x + 9y = 0 (1st)
</span><span>3x + 5y = 17 (2nd)
multiply (st) by 3 and (2nd) by 2
</span>6x + 27y = 0 (1st)
6x + 10y = 34 (2nd)
----------------------------subtract
17y = -34
y = -2
2x + 9y = 0
2x +9(-2) = 0
2x = 18
x = 9
answer
(9, -2)
1/6 divided by 3 is 1/18
1/6÷3/1 then do reciprocal so it is 1/6×1/3 equals 1/18
Answer:
First you need to set up an equation y = mx + b. m would be the monthly charge and b would be the one time fee. x represents the number of months.
To solve for the number of months with a total price of 240 we substitute 240 in for y and solve for x.
240 = 25x + 40
subtract 40 from each side
200= 25x
divide by 25
8 = x
8 months
10 + 7r = 45
7r = 35
r = 5

You did the equation a little wrong. It is A^2 + B^2 = 10^2
