Answer:

#2 is the closest to the actual roots.

Step-by-step explanation:

$12x^{3} -65x^{2} +24x+10=0$

$\frac{2}{3}$ is not a root, but 0.68078 is.

The other roots are -0.24572 and 4.9816. The closest option is #2.

<h3>Answer: Draw a straight line through (0,-7) and (1,-5)</h3>

Explanation:

You could use any two points you want. For me, the easiest is when x = 0. Plug this into the equation to get

y = 2x-7

y = 2(0)-7

y = -7

So we have x = 0 and y = -7 pair up to get (0,-7) as our first point. This is the y intercept.

Repeat for x = 1

y = 2x-7

y = 2(1)-7

y = -5

So (1,-5) is another point on this line. You only need two points at minimum to graph a straight line.

Find the positive solution and please explain how ;4;

(x + 2)² - 10 = 0 (assuming it's equal to zero)

Expand the binomial: (x + y)² = x² + 2xy + y²
Thus, x² + 4x + 4 - 10 = 0
x² + 4x - 6 = 0

$x = \frac{-4 +_- \sqrt{16 + 24}}{2}$ (by quadratic formula)
$= \frac{-4 +_- \sqrt{40}}{2}$
$= \frac{-4 +_- 2\sqrt{10}}{2}$
$= -2 + \sqrt{10}$ , since we're taking the positive solution.
