Answer: y = 2x-6
Step-by-step explanation:
So we need to write the equation of a line parallel to y=2x-1.
In parallel lines, the slope is the same, so in our new line the slope will be 2x.
We have the equation y = 2x right now. Let's plug in (4,2) for (x,y) and see if it works out, since it must pass through that point.
y = 2x
2 = 2 * 4
2 doesn't equal 8.
But if we subtract 6 from the right side of the equation -
y = 2x-6
then it checks out
2 = 2 (4) - 6
2 = 8 - 6
2 = 2
Substitute 3 into the expression for m, and 7 into it for n. So 3mn = 3(3)(7) = 3 x 21 = 63.
Answer:
x = √2 = 1.414
Step-by-step explanation:
5x-(x+2)^2=x^2-8+x
since (x+2)^2 = x^2 + 2(x)(2) + 2^2 = x^2 + 4x + 4
so
5x - (x^2 + 4x + 4) = x^2 + x - 8
-x^2 + x - 4 = x^2 + x - 8
x^2 + x^2 + x - x = -4 + 8
2x^2 = 4
x^2 = 2
x = √2 = 1.414
