Answer:
f-1(x) = (x-8)/2
Step-by-step explanation:
f(x) = 2x+ 8
y = 2x + 8
replacing y and x
x = 2y + 8
2y = x- 8
y =( x-8)/2
f-1 (x) =( x-8)/2
80% is the score percentage
Answer:
1/6
Step-by-step explanation:
4/9&3/8
4/9x3/8= ?
Multiply both numerators
= 4 x 3
= 12
Multiply both denominators
= 9 x 8
= 72
Use above values of step 2 & 3, and rewrite as below
= 12/72
so, 12/72 is equivalent to the fraction for 4/9 times of 3/8, and its simplified form is 1/6.
Answer: FH is 9x, given in the question
It's 45 if you solve for x and plug in x=5
Step-by-step explanation:
FG+GH =FH
10+7x= 9x
10=2x
x=5
FG+GH=FH
10 +7(5) = 9(5)
10 + 35 =45
