Shirley is decorating the gym for a party she has five rolls of blue streamer and 7 rolls of green streamer if each roll of blue streamer is 94 ft long and each roll of green streamer is 89 feet long how many total feed of streamer does shirley have to decorate with?

1043ft

Step-by-step explanation:

1 roll of blue streamer is 94 ft long

1 roll of green streamer is 89ft long

She has 5 rolls of blue streamer and 7 rolls of green streamer.

If 1 blue roll has a length of 94ft, 5 rolls will have a length of 5 × 94

If 1 green roll has a length of 89ft, 7 rolls will have a length of 7 × 89

The total feed of streamer she has to decorate with is calculated as follows:

(5 × 94)ft + (7 × 89)ft = 470 + 623 = 1043ft.

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
