Answer:
Step-by-step explanation:
\Select two x x values, and plug them into the equation to find the corresponding y y values.
3/5a = 1/4....multiply both sides by 5/3, cancelling out the 3/5 on the left
a = 1/4 * 5/3
a = 5/12
Answer:
b= $3.99×2 + $2.50= $10.48
Step-by-step explanation:
We have the following unknowns:
p: number of people in the club
f: ounces of fruit punch
c: ounces of cheese
b: budget in dollars
We know that
p=12
Priya is preparing 8 ounces of fruit punch per person, so:
f= 8×p = 8×12 = 96
We need 96 ounces of fruit punch
Priya is preparing 2 ounces of cheese per person, so:
c= 2×p = 2×12 = 24
We need 24 ounces of cheese
A package of cheese contains 16 ounces and costs $3.99. In order to get all the cheese we need, Priya have to buy 2 packages of cheese.
2×16=32
32>24
A one-gallon jug of fruit punch contains 128 ounces and costs $2.50. Then, Priya have to buy only one gallon jug.
128>96
The budget would be:
b= $3.99×2 + $2.50×1
<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>
