Write an equation in slope-intercept form of the line that passed through (-3, 4) and (1. 4).

1 answer:

Andrew [12]2 years ago

The two points share the same y coordinate, which means that the line is horizontal, and this in turn means that the slope is 0.

Since a line written in slope-intercept form is

$y=mx+q$

In the case of m=0 the equation is

$y=q$

where the constant $q$ is the common y coordinate shared by all points.

So, in your case, the equation is

$y=4$

What are the solutions to 3x^2 = 8x — 6?

Bond [772]

Answer:

First, let's move all terms to one side,

$\sf x^2-8x+6=0$

When given this form (ax^2+bx+c=0), there will be two solutions at the end.

1) $\sf x=\frac{-b+\sqrt{b^2-4ab} }{2b}$

2) $\sf x=\frac{-b-\sqrt{b^2-4ab} }{2b}$

where, a=1, b=-8, c=6

$\sf x=\frac{8+\sqrt{(-8)^2-4\times6} }{2} ,\frac{8-\sqrt{(-8)^2-4\times6} }{2}$

Simplify,

$\sf x=\frac{8+2\sqrt{10} }{2} ,\frac{8-2\sqrt{10} }{2}$

Simplify,

$\sf x=4+\sqrt{10}, 4-\sqrt{10}$

Hope it helps!

Answer:

The value of x is 7.

Step-by-step explanation:

First, you have to make the left side into 1 fraction by making the denormintor the same and make it into simplest form :

$\frac{x}{3} + \frac{x}{6}$

$= \frac{x \times 2}{3 \times 2} + \frac{x}{6}$

$= \frac{2x}{6} + \frac{x}{6}$

$= \frac{2x + x}{6}$

$= \frac{3x}{6}$

$= \frac{x}{2}$

Next you have to multiply both sides by 2 in order to make x the subject :

$\frac{x}{2} = \frac{7}{2}$

$\frac{x}{2} \times 2 = \frac{7}{2} \times 2$

$x = 7$

Which represents the polynomial written in standard form?<br><br> 4m – 2m4 – 6m2 + 9

zmey [24]

If you would like to write the polynomial in standard form, you can do this like this:

4m - 2m^4 - 6m^2 + 9

Writing the polynomial in standard form<span> means that you have to </span>write<span> the terms by descending degree:
</span>- 2m^4 - 6m^2 + 4m + 9

The correct result would be <span>- 2m^4 - 6m^2 + 4m + 9.</span>
