4.85×88=$426.80.
1) $426.80 is the answer
7x + 3y = m
3y = m - 7x
y = (m - 7x) / 3
4( r + 3 ) = t
r + 3 = t / 4
r = ( t - 3 )/ 4
2x + b = w
2x = w- b
x = ( w - b ) / 2
x (1 + y) = 2
x = 2 / 1 +y
Answer:
The answer is A ........
f(7) = - 25
Step-by-step explanation:
To evaluate f(7) substitute x = 7 into f(x), that is
f(7) = - 5(7) + 10 = - 35 + 10 = - 25
1
this is becasue the slope is positive
