In each table, determine if y is proportional to x. explain why or why not.
first answer receives brainliest.

yes

Step-by-step explanation:

You’re multiplying every x value by 4 to get the y values

(Someone got mad at me for not including a better explanation so here you go:

x = 3    y = 12 3(k) = 12 (divide both sides by three)

k = 4

x = 5   y = 29 5(k) = 20 (divide both sides by five)

k = 4

So on and so forth for the rest of the table

it’s supposed to be -4+45=41

step-by-step explanation:

3

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!
