Factor
what 2 numbers multily to get -12and add to get -4
-6and -2
(x-6)(x+2)=0
ser to zero
x-6=0
x=6
x+2=0
x=-2
6>-2
w=6
-2=z
3w+2z
3(6)+2(-2)
18-4
14
value is 14
option D
F(7) = 10 - 2^7
f(7) = 10 - 128
f(7) = -118
If the paintball is going 150m a second and the question asks, "starting from the distance of your friend what is the distance every TENTH of a second"
Ok so 150 meter a second so to get a tenth of a second you do 150/10 which is 15, if you start at 25 m away from you then only A and E could be correct, so now do 25+15 then that +15 and so on and you can see that letter choice E is correct
Find slope
slope between (x1,y1) and (x2,y2) is (y2-y1)/(x2-x1)
given
(-1,5) and (5,8)
slope=(8-5)/(5-(-1))=3/(5+1)=3/6=1/2
y=1/2x+b
sub a point
(-1,5)
x=-1, y=5
5=1/2(-1)+b
5=-1/2+b
add 1/2
5 and 1/2=b
y=1/2x+5 and 1/2
y=1/2x+11/2
