Answer:
r = -1
Step-by-step explanation:
This is the answer because:
1) You can take the root of both sides and solve
2) You can also isolate the variable and solve for it
1. r9 + 1 = 0, divide 9 and 0 first. 9 x 0 = 0
2. r + 1 = 0, subtract 0 and 1. 0 - 1 = -1
Hope this helps!
For this case we have the following expression:
We must find the common factor of the coefficients.
We have then:
- <em>Using common factor 3:
</em>
- <em>Using common factor 9:
</em>
Answer:
The two equivalent expressions are given by:
Answer:
k=
−2.75x2+3xy−5.5x−y/x
Step-by-step explanation:
Hi! so i see you need help with this problem let me help you and guide you through the steps :]
Let's solve for k.
k= y/x
(3x−1)−2.75(x+2)
Step 1: Multiply both sides by x.
kx=−2.75x2+3xy−5.5x−y
Step 2: Divide both sides by x.
kx/x
=
−2.75x2+3xy−5.5x−y/x
k=
−2.75x2+3xy−5.5x−y/x
Answer:
k=
−2.75x2+3xy−5.5x−y/x
