Answer:

(in attachment)

Step-by-step explanation:

you can find the points by inputting the x-values into the equation to solve for the y-values, then connecting the plotted points to create the line.

When x=-4

y=1/2(-4)

y=-2

(-4,-2)

Repeat for all values.

Solve for x. Round your answer to the nearest hundredth.

Zarrin [17]

Answer:

Option B is correct

Step-by-step explanation:

2x² - 6x + 3 = 0

Using Quadratic formula:

x = $\frac{-b+-\sqrt{b^{2}-4ac}}{2a}$

a = 2, b = -6, c = 3

x = $\frac-(-6)+-{\sqrt{(-6)^{2}-4(2)(3)}}{2(2)}$

x = $\frac{-(-6)+-\sqrt{(-6)^{2}-4(2)(3)}}{2(2)}\\$

$=\frac{6+-\sqrt{36-24}}{4}\\\\=\frac{6+-\sqrt{12}}{4}\\\\=\frac{6+-3.46}{4}\\\\$

$=\frac{6+3.46}{4}$

x = 2.37

$=\frac{6-3.46}{4}$

x = 0.63
