Answer:
Answer:
x + 2y = 2
x - 2y = -2
2x = 0
x = 0
0 + 2y = 2
2y = 2
y = 1
(0, 1)
Step-by-step explanation:
consistent and independent
Answer:
b.the system of the equations has exactly one solution at(-4.3).
Answer:
a. $185
b. 64 miles
c. 26 miles
d. x > 0
Step-by-step explanation:
a. Find C(x) when x = 40.
C(x) = 2.5 x + 85
C(40) = 2.5 (40) + 85
C(40) = 185
b. Find x when C(x) = 245.
C(x) = 2.5 x + 85
245 = 2.5 x + 85
160 = 2.5 x
x = 64
c. Find x when C(x) = 150.
C(x) = 2.5 x + 85
150 = 2.5 x + 85
65 = 2.5 x
x = 26
d. The domain of C is all the possible values of x. Since x is a distance, it doesn't make sense for it to be negative, so x > 0.
