Answer:
1 ± i(1/2)√2
Step-by-step explanation:
Write this quadratic in standard form: subtract 3 from both sides. This results in 2x^2 - 4x - 3 = 0. Let's apply the quadratic formula. The coefficients of the x terms are 2, -4 and -3, so the discriminant is (-4)^2 - 4(2)(-3), or 16 - 24 = -8.
Following the format of the quadratic formula, we get
-(-4) ±i2√8 4 ±i2√2
x = ----------------- = --------------- = 1 ± i(1/2)√2

Answer:
D: 2/3x - 13/12 = -5/12x
Step-by-step explanation:
2/3x - 5/6 = -5/12x + 1/4
To simplify, the denominator must be the same. So,
5/6 = 10/12
and 1/4 = 3/12
Then, you move the values to the same side via addition or subtraction.
2/3x (- 10/12 - 3/12) = -5/12x
2/3x - 13/12 = -5/12x
Answer:
A
Step-by-step explanation:
Remember, the equation of slope-intercept is y=mx+b
We see that for A, that the first equation's slope is -2/3. That means we are going to move down two and left five. The reason why we are going down is that the slope is negative. We also know that our y-intercept is -4. So we first plot the point (0,-4). Then we move down two and left five. We apply the same knowledge with the second equation. When we plot both equations, we get the same exact graph as the picture.
