Answer:
y= what? Whats the first equation
Step-by-step explanation:
<span>y=-4/x+1 is ambiguous, since it's not immediately clear whether you meant
-4
y = -4/x + 1 or y = ---------
x+1
I'm going to assume that the latter is what you meant.
1. Interchange x and y, obtaining:
-4
x = --------
y+1
2. Solve this for y, obtaining y+1 = -4/x, or xy + x = -4, or
-x - 4
xy = -x-4, or y = ---------
x
-1 -1 4
3. Replace y with f (x): f (x) = -1 - -----
x
This last result has the correct form.</span>
Answer:
0
Step-by-step explanation:
<span>The rate is the ratio and the unit rate is the rate when the denominator is 1.
$279 for 9 tickets.
=> rate = $279 / 9 tickets => unit rate = $ 31/ ticket
$18 for 6 volleyballs.
=> rate = $ 18 / 6 volleyballs => unit rate = $ 3 / volleyball
4 fouls in 20 minutes.
=> rate = 4 fouls / 20 minutes => unit rate = 0.2 fouls / minute
36 strikeouts in 54 innings.
=> rate = 36 strikeouts / 54 innings => unit rate = 0.67 strikeouts / inning

Answer:
10 inches
Step-by-step explanation:
They're 36 degrees, so corresponding angles are the same, so the middle line is parallel to the bottom line of the triangle.
But the middle line bisects one of the waist lines of the triangle, so this is the middle line, which is equal to half the length of the bottom line
