2n = 3n - 5 (get all of n on one side by subtracting)
-1n = -5 (when you get here you have to divide by -1 to make n positive)
n = 5
Answer:
8*15 + 3*5
Step-by-step explanation:
The CD's are 15 dollars each
She buys 8
8*15
The tapes are 3 dollars each
She buys 5
3*5
Add them together
8*15 + 3*5
Answer:
b=0
Step-by-step explanation:
y=mx+b
(0,0) means x=0 and y=o
m=2
Make b the subject of formula
b=y-mx
b=0-2(0)
b=0-0
b=0
Therefore,0=2(0)+0
=0
Therefore the equation of the slope is 0
Answer:
The answer to your question is (1, -2)
Step-by-step explanation:
See the graph below, in the graph, the solution is circled (1, -2). The solution is the point where the lines cross.
To check the answer, let's solve the system using algebra.
y = 2x - 4
y = 1 - 3x
2x - 4 = 1 - 3x
2x + 3x = 1 + 4
5x = 5
x = 5/5
x = 1
Find y by substitution
y = 2(1) - 4
y = 2 - 4
y = -2
Solution
(1, -2)
