Answer: This is <u>not</u> a function

Why not?

The input x = 2 leads to more than one output. In this case, it leads to y = 20 and y = 40 simultaneously. This is the reason why we don't have a function. A function is only possible if each input x leads to exactly one y output.

Put another way: we cannot have x repeating any values if we want a function.

Side note: We could have y repeat however. So it's possible to have a function with the two points (1,5) and (3,5).

IRINA_888 [86]

H +t = 8
$6h + $7t ≤$50

h+t = 8
h +t-t=8-t
h= 8-t

$6(8-t) + $7t ≤$50
48-6t +7t≤50
48-48+t≤50-48
t ≤ 2
h=6

$6(6) + $7(2) ≤$50
36 + 14 ≤ 50
50≤50

He can buy 6 pounds of ham and 2 pounds of turkey

1.The length of a ship model is 3% of the length of the actual ship. The model is 1.5 M long. How long is the actual ship? ____M

Vilka [71]

We have to find 100% of the number. We can use proportion to get it
3% -----------1.5m
100% -------- x
crossmultiply now
3*x=1.5*100
3x=150 /:3 divide both sides by 3
x=50m

2. Similar situation
40% ------------1000
100% -----------x
crossmultiply
40*x=100*1000
40x=100000 /:40
x=2500 - its the answer
