Answer:
Step-by-step explanation:
Solving by elimination and substitution:
x
+
y
=
7
x
−
y
=
−
3
on adding the two equations
y gets cancelled
x
+
y
=
7
x
−
y
=
−
3
2
x
=
4
x
=
4
2
=
2
substituting this value of x
in equation 1:
x
+y
=
7
2
+
y
=
7
y
=
7
−

y
=

the solution for the system of equations are :
x
=

Answer:
F
Step-by-step explanation:
So lets use the process of elimantion to find the answer.
Firs off, we can tell that this is a greater/less than or equal to inequlaity, since there is a inclosed circle, not a open one. So this leaves the top left answer and bottem right answer.
Now, we can see that the graph is from 0-15. X is at 7.
This means its x+8, because the x would be smaller, or possibly even negatibe on this graph.
My theory that can better support my annwer is if we solve for x:
x+8=15
We can subtract 8 from both sides:
x=7
And as we can see on the inequality, x is at 7 in the graph.
Hope this makes sense and helps!
Answer:
To graph a rational function, you find the asymptotes and the intercepts, plot a few points, and then ... graphing showing vertical asymptote at x = 1 ... Next, I'll find any x- or y- intercepts.
I think it’s even because if you flip one of them they will equal up on the same line. it’s basically the inverse of the other one so it’s even
