We can replace the inequality with qual sign:
2x - y = 4
x + y = -1
We can combine both question
3x = 3
x = 1
Since we know x = 1, we can solve for y by plug in in either equation:
x + y = -1
1 + y =-1
y = -2
or
2x - y = 4
2(1) - y = 4
-y = 2
y = -2
So the solution of this system of equation is the coordinate (1, -2)
Answer:
Step-by-step explanation
Look at it this way:
If you increase something by 80 percent, your multiplying it by 1.8. This goes the same way for 50 percent. If you multiply 1.8 by 1.5, you will get 2.7. Then convert 2.7 to increasing something by 170 percent. So the answer is 170 percent.

Please check the explanation.
Step-by-step explanation:
<u>Even Functions:</u>
The function is unchanged when it is reflected about the y-axis.
i.e.
f(-x) = f(x)
<u>Odd Functions:</u>
The function is unchanged when it is rotated 180° about the origin.
i.e.
f(-x) = -f(x)
<u>Neither Functions:</u>
f(-x) ≠ -f(x)
Let us check the given functions:
plug –x in for x
f(-x) = V(-x)²9
f(-x) = Vx²9
f(-x) = f(x)
Therefore, the function f(x) = Vx²9 is even function.
plug –x in for x
as

and

so
f(-x) ≠ f(x)
f(-x) ≠ -f(x)
Thus,
g(x) = |x-3| is neither an even nor an odd function.
plug –x in for x
g(-x) = (-x) + (-x)²
g(-x) = -x + x²
g(-x) = -(x-x²)
so
f(-x) ≠ f(x)
f(-x) ≠ -f(x)
Thus, it is neither an even nor an odd function.
Thus,
g(x) = x + x² is neither an even nor an odd function.
