Shana wants to use all 62 feet of the fencing she has to make a rectangular run for her dog. She decides to make the length of the run 20 feet. She writes and solves the equation 2 l plus 2 w equals 62 to find the width of the run.Which statements are true of the solution? Check all that apply.
The value of w is 10 feet.
The value of w can be zero.
The value of w cannot be a negative number.
Substitution is used to replace the variable l with a value of 20.
The subtraction property of equality is used to isolate the term with the variable w.

Answer:
Coordinates are (–6, 0), (2,0).
Step-by-step explanation:
Given the function
we have to find the x-intercepts of the graph of the function f(x).
As the value of y coordinate is 0 on x-axis which gives the x-intercepts of the function.
Put y=0 in above function we get the x-intercepts.
⇒
⇒
⇒
⇒ x=2 and x=-6
Hence, x-intercepts are 2 and -6
⇒ Coordinates (–6, 0), (2,0).

X- 2y = 3
3x - y = 2
Answers
Answer: x = 1/5 and y= -7/5
Step-by-step explanation: Let's solve your system by elimination.
Multiply the first equation by -3,and multiply the second equation by 1.
-3 (x - 2y = 3)
1 (3x - y = 2)
Becomes:
-3x + 6y = -9
3x -y = 2
Add these equations to eliminate x:
5y = -7
Then solve 5y = -7
5y/7 = -7/5
y = -7/5
Now that we‘ve found y, let’s plug it back in and solve for x.
Write down an original equation:
x - 2y = 3
Substitute -7/5 for y in x - 2y = 3:
x - 2 (-7/5) = 3
x + 14/5 = 3
x 14/5 + -14/5 = 3 + -14/5 (Add (-14)/5 to both sides)
x = 1/5
Answer:
x = 1/5 and y = -7/5
