Answer: y = (-1/2)x - 9/2</h3>
Slope = -1/2
Y intercept = -9/2
=====================================================
Work Shown:
2x + 4y = -18
2(x+2y) = -18 .... factor out 2
x+2y = -18/2 .... divide both sides by 2
x+2y = -9
2y = -9-x .... subtract x from both sides
2y = -x-9
y = (-x-9)/2 ... divide both sides by 2
y = (-x/2) - (9/2) ... break up the fraction
y = (-1/2)x - 9/2
The last equation is in slope intercept form y = mx+b with m = -1/2 as the slope and b = -9/2 as the y intercept.
If you would like to solve 3 * x^2 + 24 * x = 27, you can do this using the following steps:
<span>3 * x^2 + 24 * x = 27
</span><span>3 * x^2 + 24 * x - 27 = 0
</span>3 * (x^2 + 8 * x - 9) = 0
x^2 + 8 * x - 9<span> = 0
</span>(x + 9) * (x - 1) = 0
1. x = - 9
2. x = 1
None of the above results is correct. The correct result would be {-9, 1}.
B I believe I searched it up and that’s what I got so yeah
√(-80) = √(4²×5(-1)) = 4√5 √(-1) = 4√5i.
