Answer:
62 newspapers
Step-by-step explanation:
Let s represent the number of Sunday papers sold. Then s/2 is the number of Friday papers sold. The total revenue is ...
1.50s + 0.75(s/2) = 116.25
1.875s = 116.25 . . . . simplify
s = 116.25/1.875 = 62 . . . . . divide by the coefficient of s
62 Sunday papers were sold.
Equations of straight lines are in the form y = mx + c (m and c are numbers). m is the gradient of the line and c is the y-intercept (where the graph crosses the y-axis).
-a²-3b³+c²+2b³-c²
= -(3)² - (3×2)³ + (-3)² + (2 × 2)³ - ( -3)²
= 9 - 24 + 9 + 16 - 9
= 1
answer is 1.
