Replace f(x) with y:
y = 5x-6
Swith the variables:
x = 5y -6
Now solve for y:
add 6 to each side:
x +6 = 5y
Divide both sides by 5:
y = (x+6)/5
Now replace y with the inverse function f^-1 (x):
f^-1(x) = (x+6)/5
Answer:
a = 16
b = -6
Step-by-step explanation:
a + 2b = 4
2a + b = 26
2a + 4b = 8
2a + b = 26
3b = -18
b = -6
a + 2(-6) = 4
a - 12 = 4
a = 16
2000 - Monday
2000 - 0.10(2000) = 1800 -- Tuesday
1800 - .20(1800) = 1440 -- Wednesday
.25(2000) + 1440 = 1940 -- Thursday
net change = 2000 - 1940 = 60 <== net change
1 7/9-2/9=1 5/9
Hope this helps:)
