Given x = 3, y = 4x + 7 how do i do this

x = 3, y = 19

Step-by-step explanation:

x = 3, y = 4x + 7

Substitute x =3 into the second equation

y =4*3+7

y = 12 +7

y = 19

x = 3, y = 19

Steps to solve:

y = 4x + 7 when x = 3

~Substitute

y = 4(3) + 7

~Simplify

y = 12 + 7

~Add

y = 19

Best of Luck!

the answer is:

the correct option is the option b.

to calculate the surface area of the right cylinder, we need to use the following formula:

from the picture we know that:

so, substituting and calculting we have:

hence, we have that the correct option is the option b.

have a nice day!
