Answer:
−18c+83d+4x+1077
Step-by-step explanation:
combine all like terms
(2x+2x=4x)
(5d+78d=83d)
(-9*2c=-18c)
(1077=844+233)
Answer:
6
Step-by-step explanation:
x = area to be painted
y = gallons of paint needed
we know already one point of that function/graph :
x = 800
y = 2
so, for a simple relationship between the 2 variables we can assume
y = ax
2 = a×800
a = 2/800 = 1/400
so, we get
y = (1/400) x
for 2400 ft²
y = 1/400 × 2400 = 1/4 × 24 = 24/4 = 6
she needs 6 gallons of paint for 2400 ft².
