Since area is length times width we just have to divide the area by the length
15 3/4 divided by 5 1/4 which equals three
the width of the table is 3
Y - x = 9
12 = 1/3x
The first thing you want to do when solving a system of equations is isolating one of the variables.
Since the second equation only contains x, we can isolate x in the first equation.
y - x = 9
y = x + 9
x = y - 9
You can also solve the second equation without any previous solving.
12 = 1/3x
Multiple both sides by 3/1 or 3
x = 36
Now we can set them equal to each other
36 = y - 9
y = 45
Answer: x = 36 and y = 45
Check the picture below, the height there uses feet, but nevermind that, we can simply let it be meters, like in this case.

how hight does it go? well, that'd be the y-coordinate of the vertex.
how long does it take? well, that'd be the x-coordinate of the vertex.
Answer:
√17
Step-by-step explanation:
An irrational number is a number that cannot be expressed as a ratio of two integers. Or in other words, an irrational number can't be expressed as a fraction. You really cant divide one integer by another integer to get √17, so that makes it an irrational number.
