Abag contains yellow marbles and blue marbles, 80 in total. the number of yellow marbles is 4 less than 5 times the number of blue marbles. how many yellow marbles are there?

I believe it's 12 because 5*16=80. So, then you would subtract 4 from 16 and gat 12.

step-by-step explanation:

f(x)=2x^2 -1 

translation is a function transformation that transform the function in a way of translating. by translating the function its graph is moved  up an down. moving the function f(x) 2 units to the left will be the new function g(x) with the equation: g(x)=f(x+2)=2(x+2)^2 -1
