Step-by-step explanation:
x = -10, y = 10
y= -4x+4
m1×m2 = -1
-4 × m2 = -1
m2 = 1/4
y-y1 = m(x-x1)
y-10 = 1/4(x+10)
y-10 = 1/4x +10/4
(×4)
4y-40=x+10
4y=x+50
x-4y+50=0
Answer:
A. 
Step-by-step explanation:
We are given the functions f(x) and g(x) as,


It is required to find the function ( f+g ) i.e. ( f+g ) (x)
So, 
i.e. 
Hence, we get that
.
So, the first option is correct.
2x/3 - 5 = 21
2x/3 = 26
2x = 78
x = 39
OPTION A is the answer.....
Answer: can you explain it more?
Step-by-step explanation:
21.25% because 85/400 = .2125 which is 21.25%
