Step-by-step explanation:

Let x be the number of t-shirts.  The t-shirts are sold at $12 and it takes $20 for all the tshirts plus $8 per tshirt. The profit is defined as the price sold minus the price to make the tshirts:

We can solve for x:

The company must sell 30 tshirts to atleast make $100 profit

answer: 91

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
