Step-by-step explanation:
y=-7/5x-1/5
=-7×5/5x-1
=-35/5x-1
Answer:
5 x 7 = 35
50 - 35 = 15
Step-by-step explanation:
if five times a number subtracted from 50 is 15, do the multiplication of 5 and come out with two numbers when subtracted, you can get the 15.
so I multiplied 5 and 7, and got 35. then I subtracted it from the 50 and got the 15.
Answer:
See explanations below
Step-by-step explanation:
Given the functions
f(x) = 12x - 12
g(x) = x/12 - 1
To show they are inverses, we, must show that f(g(x)) = g(f(x))
f(g(x)) = f(x/12 - 1)
Replace x with x/12 - 1 into f(x)
f(g(x)) =12((x-12)/12) - 11
f(g(x)) = x-1 - 1
f(g(x)) =x - 2
Similarly for g(f(x))
g(f(x)) = g(12x-12)
g(f(x)) =(12x-12)/12 - 1
12(x-1)/12 - 1
x-1 - 1
x - 2
Since f(g(x)) = g(f(x)) = x -2, hence they are inverses of each other
23 = h -52
23+52 = h -52 +52
75 = h
The melting point of sea water is -2.4
