Hey there! I'm happy to help!
We have two values for y in terms of x. We can now create an equation to solve for what x is.
-4x+2=-x-1
We add x to both sides
-3x+2=-1
We subtract 2 from both sides.
-3x=-3
We divide both sides by -3.
x=1
Now, we can plug our x into one of the original equations and then solve for y!
y= -4+2
y=-2
We can also test this with the other.
y= -1-1
y=-2
Therefore, our solution is (1, -2), or x=1 and y=-2.
I hope that this helps!

You can use (a+b)2 = a2+2ab+b2.
(2x - 3)2 = (2x)2 + 2(2x)(-3) + (-3)2 = 4x2 - 12x + 9
Or you can use FOIL.
(2x - 3)2 = (2x - 3)(2x - 3) = (2x)2 + (2x)(-3) + (-3)(2x) + (-3)2 = 4x2 - 12x + 9

Answer:
See below.
Step-by-step explanation:
The question tells us that 2.54 cm is equivalent to 1 inch. The next part wants to know what 5.08 cm is in inches. We can just divide 5.08 by 2.54 to figure that out.
5.08/2.54 = 2
This means that 5.08 cm is 2 inches.
The next one wants to know how many centimeters 10 inches is. We can 2.54 and multiply it by 10.
2.54 · 10 = 25.4
This means that 25.4 cm is 10 inches.
