F^-1(x)= (x+7)/2
it's the inverse so adding is subtracting and multiplication is divison
Answer:
b=c-ax/y
Step-by-step explanation:
1) ax + by = c
-ax
2) by = c - ax
3) by/y = b and c - ax/y
4) b = c-ax/y
The direct variation between x and y may be written as,
y = kx
where k is the constant of variation. From the first set of values of the variables,
12 = k(8)
the value of k is 1.5. Substituting the next set to the same equation,
y = 1.5(14)
The value of y is 21.
2 5/9 +1 2/3
= 2 5/9 + 1 6/9
= 3 11/9
= 4 2/9
Answer:
Z=16
Step-by-step explanation:
just add 12 to both sides so you are left with only Z on one side
