Answer:
The value of x is 4 and y is (-9)
Step-by-step explanation:
<h3><u>Given</u>;</h3>
<h3><u>To </u><u>Find</u>;</h3>
- Value of x
- Value of y
- By Elimination Method
Now, Name the equation
x + 2y = -14 ...(1)
x – y = 13 ...(2)
Now,
x + 2y = -14
x – y = 13
<u>– + –</u>
3y = -27
y = -9
Now, put the value of y in equation 2
x – y = 13
x – (-9) = 13
x + 9 = 13
x = 4
Thus, The value of x is 4 and y is (-9)
<h3>
<u>For </u><u>Verification</u>;</h3>
x + 2y = -14
4 + 2(-9) = -14
4 – 18 = -14
-14 = -14
x – y = 13
4 – (-9) = 13
4 + 9 = 13
13 = 13
Hence, L.H.S = R.H.S

the building is 265.25m long and the scale is 1 inch on the drawing is equal to 25 meters of the building. To find the answer lets scale the building. If the real length of the building is 256.25 meters, then the number of inches will be: 256.25/25=10.25 inches.
There is no restriction upon the domain, the x values, and is all real numbers or (-oo,+oo)
From such it is clear that the domain also contains all real numbers.
The range of f(x) is (-oo,+oo)
