The function g is defined by g(x)=2x^2-3.
find g(2y)

g(2y) = 8y^2 -3

Step-by-step explanation:

g(x)=2 x^2   -3

Let x=2y

g(2y) = 2 (2y)^2 -3

         = 2 (4y^2)  -3

         = 8y^2 -3

step-by-step explanation:

the ratio of white tiles to blue tiles is 48: 16. the ratio in it's simplest form is 3: 1.

step-by-step explanation:

ratio: take the first number and add a colon next to it, then add the second number after that. make sure the ratio order matches up with the written problem!

simplest form: we can simplify the ratio 48 : 16 by dividing both terms by the greatest common factor (gcf).

the gcf of 48 and 16 is 16.

divide both terms by 16:

48 ÷ 16 = 3

16 ÷ 16 = 1

reducing to simplest form:

48 : 16 = 3 : 1
