Answer:

-3

Step-by-step explanation:

6x take 4x equals 2x

So it'll be 2x+4=-2

Then you do - 2 take 4 which is - 6

So then it is 2x=-6

-6÷2=-3

Hope this helps you :)

Answer:

x=-3

Step-by-step explanation:

6x+4=4x-2

Subract the x on the right side on both sides

Equation should now be:

2x+4=-2

Now subtract the 4 from both sides

The equation is now:

2x=-6

Now all you have to do is divide the x on both sides

Your answer is now x=-3

What are the exact solutions of x^2 − 3x − 7 = 0?

bulgar [2K]

<u>Given</u>:

The given equation is $x^{2} -3x-7=0$

We need to determine the exact solutions of the equation.

<u>Exact solution:</u>

The exact solution of the equation can be determined by solving the equation using quadratic formula,

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

From the equation the values are a = 1, b = -3 and c = -7

Thus, substituting these values in the equation, we get;

$x=\frac{-(-3) \pm \sqrt{3^2-4(1)(-7)}}{2(1)}$

$x=\frac{3 \pm \sqrt{9+28}}{2}$

$x=\frac{3 \pm \sqrt{37}}{2}$

Thus, the exact solutions of the given equation is $x=\frac{3 \pm \sqrt{37}}{2}$

Hence, Option A is the correct answer.

Which point lies on the line with point-slope equation y-3=4(x+7)

Arte-miy333 [17]

Point slope equation for point (h,k) and slope m is given by

y-k=m(x-h)

compare given equation with formula

we get h=-7, k=3

so the required point is (-7,3)
