Answer:
Correct answer: B
Step-by-step explanation:
Syntax: in piecewise functions such as the one attached, the "if:" section shows the domain, or x-axis values which that function pertains to.
In the graph, you can see that the graph is defined for (not-including 1 because there is an open hole there, indicating it is not part of the domain), and
.
Now that we know the domain, we can attach it to the graphs that lie on those domains.
We see that the leftmost line appears to have a positive slope and a negative y-intercept, and that the second line should have a positive y-intercept and a negative slope.
At this point, you can just start crossing off answers that don't meet this criteria.

Answer:
x=6
Step-by-step explanation:
Hi there!
<u>1) Determine the perimeter of the square</u>
We're given that the perimeters of the square and the rectangle are equal. Therefore, after finding the perimeter of the square, we will also know the perimeter of the rectangle.
Find the side length of the square using the area formula:
where l is the side length
Plug in the given area 121 in.²
Take the square root of both sides
Therefore, the side length of the square is 11 inches. Plug this into the perimeter formula:
where l is the side length
Therefore, the perimeter of the square is 44 inches. The perimeter of the rectangle is also 44 inches.
<u>2) Determine the value of x</u>
Use the formula for the perimeter of a rectangle:
where l is the length and w is the width
Plug in 3x and x-2 as the length and width
Plug in the perimeter 44 in.
Expand the parentheses
Add 4 to both sides to isolate 8x
Divide both sides by 8 to isolate x
Therefore, the value of x is 6.
I hope this helps!
