The cost of an order of 10 hamburgers, 9 fries, and 3 shakes can be represented by the polynomial 10h + 9f + 3s. find the cost of the order if hamburgers are $1.89 each, fries are $.79 each, and shakes are $1.49 each.

1.89*10=18.9
.79*9=7.11
1.49*3=4.47

10h+9f+3s= 30.48

I’m going to infer you said parallel.solve for yy= -1/2x+7/4lines that are parallel have the same slope, different y intercept.so we know m is -1/2then from there solve for y intercept.

At a constant it will take one hour to travel 32 mi.at that speed it will take 1/2 hr to travel the remaining 16 mi.it will take 1+1/2 hr to travel the 48mi @ 32mph.so 1 hr = 60 min& 1/2 hr = 30 min1+1/2 hr = 90 min.there are 60s in each 90 × 60 = 3600 seconds.the real question seriously is he why are they driving so slow? ! lol.
