Answer:

(-1,-2)

Step-by-step explanation:

$6x-y=-4\\y=6x+4\\y=6(-2)+4=-8\\y=6(-1)+4=-2\\y=6(0)+4=4$

so the only one is (-1,-2)

Which of the following statements are true about the equation below?

emmasim [6.3K]

Answer:

Option 1, 2, 5 are the correct answer.

Explanation:

We have the quadratic equation, $x^2-6x+2=0$

First derivative of the equation is given by 2x - 6 = 0

So x = 3

At x = 3 the value of quadratic equation is extreme, corresponding y is given by $3^2-6*3+2=11-18=-7$ , So extreme value is at (3,-7)

Second derivative of the quadratic equation is given by 2 ( positive value)

Second derivative is positive so graph of equation has a minimum value.

Now root of the equation $x^2-6x+2=0$ is given by

$\frac{6+\sqrt{(-6)^2-4*1*2}} {2} =3+\sqrt{7}$

$\frac{6-\sqrt{(-6)^2-4*1*2}} {2} =3-\sqrt{7}$

Option 1, 2, 5 are the correct answer.

3/2 which is the slope

Substitue in the slope intercept formula

So y=mx+b

Y=3/2x+b

Substitue the origin in the equation

0=3/2(0)+b

0=0+b

So B=0

Therefore g(x)=3/2x
