-2 is the x coordinate and 7 is the y coordinate. If you plug them into the equation y= 2x - 1, you end up with 7 = 2(-2) - 1; 7 = -4 -1; 7 = -5 which isn’t true so you know that point isn’t on the line.
For example, let’s say you have an x coordinate for a point on the line but need to figure out what the y coordinate is. Let’s say x = 3. You plug 3 in for x in the equation y = 2x -1 and solve for y.
So y = 2(3) -1 which is y = 6-1 which is y = 5 So the answer would be (3,5) (x-coordinate, y-coordinate). You can check your answer by plugging 5 into the equation for y and solving for x.
If you take (3,5) and plug them into the equation, y = 2x - 1, 5 = 2(3) - 1 which is 5 = 6 - 1 which is 5 = 5. You know the coordinates (3,5) belong to a point on the line because the equation matches.
I went the long way around on the explanation and I hope I didn’t confuse you!
Th answer is 16 becase if u just divide 224 and 14 you will have the aswer and i just did the math for you
Answer:
Step-by-step explanation:
Let
x------> the length of the original play space
y-----> the width of the original play space
we know that
The area of the original play space is equal to
The area of the new play space is equal to
Find the difference
