Answer:
NO SOLUTION
Step-by-step explanation:
We can make this problem easier to understand if we write the system vertically:
2x-y=7
y=2x+3
and then rewrite the first problem in the form y = mx + b:
2x-y=7 ↔ y + 7 = 2x ↔ y = 2x + 7
y=2x+3
Note how these two equations have the same slope, but different y-intercepts. This tells us that the two lines are parallel, which in turn tells us that they never intercept one another.
Thus, this system has NO SOLUTION.
Answer:
the answer is 25
Step-by-step explanation:
and you get it by multiplying 9×4 keep the answer on paper then do 2×2 which is 4 subtract the two answers and subtract 7 and then you get 25, your welcome
Answer:
1 because 2x is the slope, so 1 should be the y-intercept
9x-4=5x-6
+4 +4
9x=5x-2
-5x-5x
4x=-2
divide by 2 on both sides
x=-2 or
x= 4/9
In order to factor a polynomial, you have to find its roots
So that you can factor it as
So, in this case, we're looking for the solutions of
So, the polynomial can be written as
