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
Answer:
-2
Step-by-step explanation:
Remember to follow PEMDAS. First solve parenthesis, power, multiplication, then add.
(5 - 2) = 3
(-4)² = (-4)(-4) = 16
3(-6) = -18
16 + (-18) = 16 - 18 = -2
-2 is your answer.
