Answer:
The answer would be y = -1/2 x + 3
Step-by-step explanation:
So to solve this problem we have to look at the graph.
We have to put it into y = mx + b.
The B would be where the line crosses the y - intercept.
The mx would be how fast is the line going up/down.
If it is going down, it would be negative.
If it is going up, it would be positive.
I hope I helped.
When a point lies on the x-axis, its y- coordinate is 0. The same is true for the reverse. So if your point lies on the y-axis, its x coordinate will be 0.
Answer:
C. x + 9

Answer:
25 inches
Step-by-step explanation:
If square has a perimeter of 20 inches, the length of each side is:

After cutting the square in half, we are left with two rectangles of 5 in x 2.5 in
Attaching those two smaller rectangles by their short end (2.5 in side), gives us a new rectangle with a height of 2.5 in and a length of 10 in (sum of the 5 in sides in each rectangle). The perimeter of this new rectangle is:

The perimeter is 25 inches.
Answer:
x = 150
Step-by-step explanation:
(n-2)180 (n = the amount of sides)
(12 - 2)180
(10)180
1800
1800/12 = 150
