Answer:
Step-by-step explanation:
X + y - Z=3 ------------------(I)
2y + 2z = 6 ------------------(II)
-2y - Z = -2 ------------------(III)
Multiply equation (III) by 2 and add equation (II) & (III)
(II) 2y + 2z = 6
(III)*2 <u>-4y - 2z = -4</u> {Now add and z will be eliminated}
-2y = 2
y = 2/-2
y = -1
Plugin y =-1 in equation (II)
2*(-1) + 2z = 6
-2 + 2z = 6
2z = 6 + 2
2z = 8
z = 8/2
z = 4
Plugin y = -1 & z = 4 in equation(I)
x - 1 - 4 = 3
x - 5 = 3
x = 3 + 5
x = 8

this is not middle school math no way
Step-by-step explanation:
Based on the sample response given, the statements included in the explanation on the horizontal line test are:
- a reference to the horizontal-line test.
- a statement that the function is one-to-one.
- inverse is a function.
<h3>What is the horizontal-line test?</h3>
The horizontal line test is used to not only find out if a graph has an inverse function, but also if that inverse is also a function itself.
To pass the horizontal line test, the function has to be one-to-one which means that a horizontal line can intersect the graphed function at one point in all places. If this happens, then there is an inverse and the inverse itself is a function.
