Answer:
4650 add 1500+1800+3400 u get 6700
then you get the tuition cost then subtract it by 6700
your final answer is 4650 dollar
A.
let the number be n.
2n+5=45
2n=40
n=20
The slope of the given line is ∆y/∆x = (4-6)/(5-1) = -2/4 = -1/2. The slope of the desired (perpendicular) line is the negative reciprocal of this, -1/(-1/2) = 2.
The point-slope form of the equation for a line with slope m through point (h, k) is
... y - k = m(x - h)
For slope 2 and the given point, your equation can be
... y + 6 = 2(x + 2)
X will equal 7.
4(5x-2)=2(9x+3)
20x-8=18x+6
20x-18x=8+6
2x=14
x=7
2 is the answer. Hope this helps!
