Answer:
A) -2y + 2x >= 7x+y+5
Step-by-step explanation:
I can't remember how to get there by actually doing math, but I used a calculator on a program called Desmos (don't know if you've heard of it?). It's great because they have lots of types of calculators for any kind of math you're doing. I used the graphing calculator for this one. There's also a scientific calculator which I used a lot throughout middle school when we had to do operations with PEMDAS OR GEMS.
To find the graphing calculator for future problems like this, just type in Desmos Graphing Calculator and it should come up.
Hope you find it useful.
You start of with a number, ( this number can be any number) so think of it as an unknown number. the number shall be denoted as x
so you have x
you want triple the number
3x
you also want to double the number
2x
you want the difference so you subtract these two terms
3x-2x
Answer:
x = 
Step-by-step explanation:
We know that we have to find the roots of the equation - which is another way of saying the x-intercepts, or the points that are on the x-axis that the graph passes through. All points on the x-axis have a y-value of 0. So, in order to find the roots for this equation, we need to find which values of x make the y equal 0.
The equation has already been factored out. So, we just need to find which values of x for each of the expressions in the parentheses will make the result 0. To do this, set the expressions in the parentheses to 0 and isolate x.
1) First, let's look at (2x-3). Write the equation 2x-3 = 0. Then, isolate x:
Therefore, 
is one of the roots.
2) Next, let's look at (x+5). Write the equation x+5 = 0. Then, isolate x:
Therefore, -5 is a root as well.
The roots of the equation would be and -5.

Answer:
We know that the Pythagorean Theorem is a² + b² = c². First lets start with 6, 8, and 10. There is a simple way to know that these are Pythagorean triples. They make up what is called a 3-4-5 triangle. 3 x 2 is 6, 4 x 2 is 8, and 5 x 2 is 10. Next 5, 12, and 13 are Pythagorean triplets because 5² + 12² = 13². Because both of these form right triangles, we know that they are Pythagorean triplets.
