Answer:
a. C = 12x + 110; b. $290
Step-by-step explanation:
a. The polynomial
Let L = cost of flip-flops
and S = cost of sandals
Then
C = L + S
= 40 + 4x + 70 + 8x
= 12x + 110
b. The cost
C = 12 × 15 + 110
= 180 + 110
= $290
The cost of making 15 flip-flops and 15 sandals is $290.
Answer:
Quadrant II
Step-by-step explanation:
Since there are 360 degrees in a circle we will subtract it from 860 until we get a number less than 360
Since it less than 180 but more than 90 it will be in the second quadrant
