Answer: 65
Step-by-step explanation:
First you have to multiply. 150 x 0.4 = 60
Then you have to subtract 60 from 150, you get 90. Then subtract 25. 90 - 25 = 65.
Answer:
1/15
Step-by-step explanation:
The first thing to do is to change both denominators so that they're the same. In this case, that would be 15.
Then, whatever you do to the denominator, you must also do to the numerator.
+ x = 
X = 1/15
Y = -4x - 2
P (-16, -11)
a = -4, b = 0, c = -2
m = -a/b
m = -(-4)/(-2)
m = 4/(-2)
m = -2
y-yo = m(x-xo)
y-(-11) = -2[x-(-16)]
y+11 = -2(x+16)
y+11 = -2x-32
2x+y+11+32 = 0
2x+y+43 = 0
