Dave has 12$ to spend on a 7 dollar book and two birthday cards (c) for his friends how much can he spend on each card if he buys the same card for the each friend

2.50

Step-by-step explanation:

So if you have a budget of 12 dollars, and the book is 7 dollars, subtract 12-7 and you get 5 dollars. And half of 5 dollars is 2.50. And if there is 2 cards, then that means that 1 card is 2.50

shift 4 units up, and 1 unit left.

it will translate f(x) = 3^x to g(x) = 3^(x+1) + 4
