So basically the x will want to be singled out and 3/2-y=the variable
Answer:
MG, MH, MO, LG, LH, LO
Step-by-step explanation:
since pepperoni not allowed, only G,H,O are allowed. so 6 choices available
Answer:
- f⁻¹(x) = (x + 1) / (x - 2)
- f⁻¹(1 ) = - 2
Step-by-step explanation:
<u>Given function:</u>
- f(x) = (2x + 1) / (x - 1)
<u>Find its inverse, substitute x with y and f(x) with x, solve for y:</u>
- x = (2y + 1) / (y - 1)
- x(y - 1) = 2y + 1
- xy - x = 2y + 1
- xy - 2y = x + 1
- y(x - 2) = x + 1
- y = (x + 1) / (x - 2)
<u>Substitute y with f⁻¹(x):</u>
- f⁻¹(x) = (x + 1) / (x - 2)
<u>Find f⁻¹(1 ):</u>
- f⁻¹(1 ) = ( 1 + 1) / (1 - 2) = 2 / - 1 = - 2
The fewest number of expressions is 3.
<u>Answer:</u> 100
<u>Reasoning:</u> The median is the "middle value" and to find it put the numbers in order from least to greatest.
22, 43, 100, 102, 108.
now take a number from both sides
43, 100, 102
Once again.
100
So 100 is the median.
