Ap comp science principals is really easy for an ap class, probably because its an intro course, i took it this year, don’t overwhelm yourself id personally take precalc honors
<span>V (sale value) = $ 132000
P (profit) = 10% on the sale, ie 10/100 * 132000 = 1320000/100 = $ 13200
C (cost) = ?
As:
V = C + P
132000 = C + 13200
C = 132000-13200
C = 118800
Answer:
He paid $ 118800 for the house (</span><span>Purchase price of house)</span>
8x + 3y = 20.50
-
4x+5y=22.50
=
4x-2y=-2, so you have to divide each number by 2, then
2x-y=-1, so
-y=-1-2x /-1, y=1+2x, then replace it with one original equation like the first one for instance:
8x+3(1+2x)=20.50, then
8x+3+6x=20.50, then
14x=20.50-3
14x=17.5
x=1.25, then solve y:\
y=1+2*(1.25)
y=1+2.5
y=3.5,
So answer is x=1.25, and y=3.5
Draw a number line and place a dark dot at x=(2). Place a circle at x=0.
Connect the circle at x=0 to the dot at x=2 with a line segment.
Not knowing what your M means, I can't go any further here helping you. Please explain where M came from and what it means.
12x-2 I think that’s right I’m not really sure
