Answer:

Quadratic Equation:

$3x^2=2x +5$

$\text{Standard Form: } 3x^2-2x-5=0$

From the standard form of a Quadratic Function, we get:

$a=3,\:b=-2,\:c=-5$

Discriminant:

$\Delta=\left(-2\right)^2-4\cdot \:3\left(-5\right)$

$\Delta=\left(-2\right)^2+4\cdot \:3\cdot \:5$

$\Delta=64$

From the discriminant, we conclude that the equation will have two real solutions.

State that:

$b^2-4ac$

$b^2-4ac =0:\text{The equation has 1 real solution}$

$b^2-4ac >0:\text{The equation has 2 real solutions}$

By the way, solving the equation given:

$x=\frac{2\pm\sqrt{64}}{2\cdot \:3}$

$x=\frac{2\pm\sqrt{64}}{6}$

$x=\frac{2\pm8}{6}$

$x_{1} =\frac{10}{6}=\frac{5}{3}$

$x_{2}=\frac{-6}{6} =-1$

A softball team played 149 games. The team won 8 more than two times the number of games they lost. How many games did they lose

BlackZzzverrR [31]

The number of game the softball team lose is 47 games.

<h3 /><h3 /><h3>The softball team played 149 games. </h3>

Total games played = 149 games

The team won 8 more than two times the number of games they lost.

Let

the number of games they lost = x

Therefore,

number of game won = 8 + 2x

The number of game they lose can be calculated as follows:

8 + 2x + x = 149

8 + 3x = 149

3x = 149 - 8

3x = 141

x = 141 / 3

x = 47

Therefore, the team lost 47 games.

Answer:

1 / 36

Step-by-step explanation:

So there's one number on a cube greater than 5. That is 6.

There is 1 / 6 chance of getting 6 the first time, and another 1 / 6 change for getting 6 the second time.

1 / 6 * 1 / 6 = 1 / 36
