Answer:
Step-by-step explanation:
The given equations are:
(1)
and 
(2)
Now, simply adding equation (1) and equation (2), we get
Now, substituting the value of x=6 in equation (2). we get
Thus, the values of x and y are 6 and 1 respectively.
In order to solve the system of solution, beau can see that in both the given equations, coefficient of y is same and is with opposite sign, thus simply adding both the equations will eliminate y and she will get the value of x and then substituting the value of x in any of the equations, she can get the value of y. With this, she can get closer to the solution.
Answer:
17 + 23 = 40
23 - 17 = 6 the other person did it right.
The value of f(-6) is -12.2
Explanation:
Given that the function 
We need to determine the value of f(-6)
The value of f(-6) can be determined by substituting the value for 
in the function and simplify the function.
Hence, let us substitute in the function, we get,
Let us apply the rule 
, we get,
Multiplying the numbers, we get,
The value of 
Substituting the value of , we get,
Subtracting the denominator, we have,
Dividing, we have,
Rounding off to the nearest tenth, we have,
Thus, the value of f(-6) is -12.2
Given the perimeter and length of the garden, the width of the garden was extended by 4 feet
<h3>How to find width of the garden</h3>
- Length of the garden = 12 feet
- Width of the garden = 7 feet
- Width extension =( 7 + w) feet
Perimeter = 2(length+ width)
46 = 2{12 + (7 + w)}
46 = 2(12 + 7 + w)
46 = 2(19 + w)
46 = 38 + 2w
46 - 38 = 2w
8 = 2w
w = 8/2
w = 4 feet
