The answer is 9x^3-6x^2+3x
Answer:
the answers are A D and E
You would first have to find common denominators for the fractions. In this case it would be 10. So your new equation would be 3 5/10 - 2 4/10. Once you do this you can then subtract and solve getting the answer of 1 1/10
First, you have to answer the question in simplest form:
<span>3x - 4y = 5 (Subtraction property of equality) Subtract both sides by -3x.
-4y = -3 +5 (Divide both side by -4.))
</span>y = 3/4x(slope) 4/5 y-intercept.
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
