Answer:
A = 3, B = 10
Step-by-step explanation:
= 
= 
× 
× 
= 3i
in the form Ai
with A = 3 and B = 10
By replacing you get:
5*7-2*11+3*(-1) = 35-22-3= 10
so the answer is 10.

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
