Which shows the correct substitution of the values a, b, and c from the equation 1 = –2x + 3x2 + 1 into the quadratic formula? Q

Tanzania [10]

First of all, you have to manipulate the equation into the standard

$ax^2+bx+c=0$

form. You can simplify the 1's on both sides and you have

$3x^2-2x=0$

This means that your coefficients are

$a=3,\quad b=-2,\quad c=0$

And since the solving formula is

$x_{1,2}=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}$

Plugging your values yields

$x_{1,2}=\dfrac{-(-2)\pm\sqrt{(-2)^2-4\cdot 3\cdot 0}}{2\cdot 3}$

An above ground swimming pool is leaking after 1 and 1/2 hours the pool has leaked 7/8 of a gallon of water how many gallons of

Aleksandr [31]

Answer:

In 1 hour the amount of water leaking from pool = $\frac{7}{12}$ gallon of water

Step-by-step explanation:

Given as :

The amount of Leaking of water from the pool = $\frac{7}{8}$ gallon

The time taken fro leaking $\frac{7}{8}$ gallon of water = 1 $\frac{1}{2}$ gallon hour

Or The time taken fro leaking $\frac{7}{8}$ gallon of water = $\frac{3}{2}$ hour

∵ $\frac{3}{2}$ hour takes for leaking $\frac{7}{8}$ gallon of water

∴ In 1 hour the amount of water leaking from pool = $\frac{7}{8}\setminus \frac{3}{2}$

Or, In 1 hour the amount of water leaking from pool = $\frac{7}{12}$ gallon of water Answer

6. Consider the inequality 12<-3 (x + 4). Which value of x is part of the solution set of this inequality?

Naily [24]

Answer:

-8

Step-by-step explanation:

12<-3 (x + 4)

1. distribute to the -3 to the x and 4 and should get

-3*x = -3x

-3*4 = -12

12< -3x - 12

2. now you get rid of the common factors which is -12 so add 12 to both sides and should get

-12+12=0

12+12=24

24< -3x

3. to get x by itself you will have to get rid of -3, so how to do that is divide -3 to both side and should get

-3x/-3= x

24/-3= -8

-8<x
