Y = 3x + 4, what is y when x is 1, 2, and 3?

y(1) = 7

y(2) = 10

y(3) = 13

Step-by-step explanation:

y = 3(1) + 4

y = 3 + 4

y = 7

y = 3(2) + 4

y = 6 + 4

y = 10

y = 3(3) + 4

y = 9 + 4

y = 13

good luck, i hope this helps :)

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.
