Leo’s dad brought home some bagels and muffins. Each bagel cost $0.90 and each muffin cost $0.80. Altogether he brought home 9 items for a total cost of $7.60.

Leo's dad bought 4 bagels and 5 muffins.

Step-by-step explanation:

The total cost was 7.60, and had 9 items. I figured that the solution of           (__ x 0.9) needed to end with 60 cents.

4 x 0.9 = 3.6

5 x 0.8 = 4.0

3.6 + 4.0 = 7.60.

Total of 9 items, adding up to 7.60.

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
