Answer:
So both equations are true
Step-by-step explanation:
#4 was asking you to substitute x = 4 into both equations to see if it's the solution of the equations.
Substitute x = 4
Ritz equation
y = 30x + 20
y = 30(4) + 20
y = 120 + 20
y = 140
Smits equation:
y = 15x + 80
y = 15(4) + 80
y = 60 + 80
y = 140
Both companies charged same price $140 for 4 days
So both equations are true
(t + 12) ^ 2
(t + 12) (t + 12)
t ^ 2 + 12t + 12t + 144 144 24
t ^ 2 + 24t + 144 -------|--------
(t + 12) (t + 12) = 0 12,12 | 24
t = -12
Okay so
= 75 minutes. Now we divide 40 by 75. 40÷75=0.53333333333333 miles. We know 1 hour is 60 minutes so we are going to multiply 0.5333333333333 by 60. 60×0.533333333333=32 miles. Therefore, your answer is 32 miles.
