Answer:

Yes, this is a function.

Step-by-step explanation:

This is a function because every input goes to exactly one output. Although 1 is listed twice in this example, it still goes to the same output of 15.

How do I Graph y= –73x+2 .

Romashka-Z-Leto [24]

Answer:

See attachment

Step-by-step explanation:

You can obtain any two points on the graph of $y=-73x+2$ and use it to draw its graph.

When x=0, $y=-73*0+2=2$

So you plot (0,2)

When x=1, $y=-73*1+2=-71$

You again plot (1,-71).

With a straight edge you can now draw a straight line through the two points.

one fruit punch had 40% fruit juice and another is 90% fruit juice. how much of the 40% punch should be mixed with 30 gallons of

sashaice [31]

A = fruit juice 40%

B= 90% juice

then

30 gallons + A = 55• C/100

30 gallons + N • (40/100) = (30 + N)• (55/100)

Now solve this equation, for N

3000 + 40N = (30+N) •55

then

3000 - 1650 = 55N - 40 N = 15N

1350 = 15 N

then

N= 1350/15 = 90

Then answer is

Should be mixed 90 gallons of 40% fruit punch
