Answer:
see explanation
Step-by-step explanation:
The minimum is at the vertex (- 3, 1 ), that is y = 1
Since the graph is a minimum then it opens vertically up U
The range of the values of y are therefore
range [ 1, ∞ )
Direct variations can be set up as proportions
5/75 = 8/x....5 hrs to 75 dollars = 8 hrs to x dollars
now we cross multiply
(5)(x) = (75)(8)
5x = 600
x = 600/5
x = 120 <== so he makes $120 for working 8 hrs
another way...
75/5 = 15..so he makes 15 per hr
15 * 8 = 120
The answer is 5a+15b-10
5 x a is 5a. 5 x 3b is 15b and 5 x -2 is -10.
You then put them together 5a+15b-10
