Answer:
Step-by-step explanation:
f(x)=42-0.45(x) Solution 13.5 dollars expend in 30 Finishing nails
f(x)=42-0.60(x) Solution 18 dollars expend in 30 Common nails
D
substitute x = - 6 into the equation
y = 17 - (- 6 ) = 17 + 6 = 23 → D
There is NO solution.
Cancel t on both sides (1/5 = 7/8).
Since 1/5 = 7/8, that doesn't make any sense so that is inapplicable ( So NO answer).
