Answer:

$\huge{ \boxed{ \bold{g = - 2}}}$

Step-by-step explanation:

In order to find g we have to use the formula for finding the slope of the line passing through two points that's

$m = \frac{y_2 -y_ 1}{x_2 -x_1 } \\$

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are (g, -1) and (2, 5) and m = 3/2

We substitute it into the equation and find g

That's

$\frac{3}{2} = \frac{5 - - 1}{2 - g} \\ \frac{3}{2} = \frac{5 + 1}{2 - g } \: \: \: \: \: \: \: \frac{3}{2} = \frac{6}{2 - g} \\ \\ 3(2 - g) = 6(2) \\ 6 - 3g = 12 \\ - 3g = 12 - 6 \\ - 3g = 6 \\ \\ \frac{ - 3g}{ - 3} = \frac{6}{ - 3} \\ \\ g = - 2$

We have the final answer as

Hope this helps you

What is the solution set of the quadratic inequality 6x2+1<0

Free_Kalibri [48]

Answer:

Solution set of the quadratic equation is, Empty set

Step-by-step explanation:

Given the quadratic equation: $6x^2+1>0$

Subtraction property of equality states that you subtract the same number to both sides of an equation.

Subtract both sides by 1 we get;

$6x^2+1-1>0-1$

Simplify:

$6x^2>-1$

Division property of equality states that you divide the same number to both sides of an equation.

Divide both sides by 6 we get;

$\frac{6x^2}{6} >\frac{-1}{6}$

Simplify:

$x^2>\frac{-1}{6}$

For any x in real number there does not exist any number x which satisfy

$x^2>\frac{-1}{6}$ , therefore, there is no solution for this set of the quadratic inequality or in other word we can say that set of the solution is Empty set.
