Answer:
There are multiple answers, choose one
F. (x, y) (x + 6, y + 5)
G. (x, y) (x - 6, y - 5)
H. (x, y) (x - 6, y + 5)
J. (x, y) (x + 6, y - 5)
Step-by-step explanation:
There are two changes of sign, so there are 2 or 0 possible positive roots.
There are two changes of sign, so there are 2 or 0 possible negative roots.
There are 4,2 or 0 possible non-real roots.
27 because 18 divided by 2 is 9 so you just add 9 more to $18
5x -2y = 26. We know that x = y + 4. Substitute the value of x in and you get 5y + 20 - 2y = 26 If yous simplify this you get 3y + 20 = 26
Take away 20 from both sides and you end up with 3y = 6
Now did use both sides by 3
You end up with y = 2
Now to find x you just simplify the value of y into x = y + 4. You end up with x = 2 + 4. Now you know that y = 2 and. X = 6
Answer:
The number of solutions to the given set of equations is 0.
Step-by-step explanation:
Number of solutions of a system of equations:
System of equations: ax = b
If a = 0 and b = 0, infinite solutions.
If a = 0 and b != 0, zero solutions.
If a != 0 and b != 0, one solution.
We are given the following system of equations:
y = 7x + 12
y = 7x + 2
So
7x + 12 = 7x + 2
7x - 7x = 2 - 12
0x = -10
a = 0, b != 0, so zero solutions.
The number of solutions to the given set of equations is 0.
