Identifying the values a, b, and c is the first step in using the Quadratic Formula to find solution(s) to a quadratic equation.
MatroZZZ [7]

Answer:

To find a b and c in a quadratic equation, the x^2 number is a, so 7x^2 is your a value, your b value is just the x, so your b value is -9, and your c value is the regular number, which is 18.  a=7x^2 b=-9x c = 18.  So your answer is answer B.

Answer: y \in R; y \neq 0
Explanation: For this, it is often best to find the horizontal asymptote, and then take limits as x approaches the vertical asymptote and the end behaviours.

Well, we know there will be a horizontal asymptote at y = 0, because as x approaches infinite and negative infinite, the graph will shrink down closer and closer to 0, but never touch it. We call this a horizontal asymptote.
So we know that there is a restriction on the y-axis.

Now, since we know the end behaviours, let's find the asymptotic behaviours.

As x  approaches the asymptote of 7⁻, then y would be diverging out to negative infinite.
As x approaches the asymptote at 7⁺, then y would be diverging out to negative infinite.

So, our range would be: y \in R; y \neq 0

Susan was thinking of a number that when she multiplies it by two and then
Gnesinka [82]

Answer:

-4

Step-by-step explanation:

Let the number be x

If she multiplies the number by 2, it will become 2x

If divided by 4, it will be 2x/4, if she multiplies the result by itself, we will have:

2x/4(2x/4) = 4x/16

If she subtract the original number from 6 and divide by 10, we will have;

x-6/10

Equating both expressions

4x/16 = x-6/10

Cross multiply

4x(10)= 16(x-6)

40x =16x-96

40x-16x = -96

24x = -96

x = -96/24

x = -4

Hence the number is -4

What value of x is in the solution set of 3(x – 4) ≥ 5x + 2?
alisha [4.7K]
Hey!


To start solving equation, we should first distribute the parenthesis. We do this so that we can get rid of the parenthesis.

<em>Original Equation :</em>
3 ( x - 4 ) ≥ 5x + 2

<em>New Equation {Changed by Distribution} :</em>
3x - 12 ≥ 5x + 2

Next, we'd add 12 to both sides of the equation to get rid of the 12 on the left side of the equation.

<em>Old Equation :</em>
3x - 12 ≥ 5x + 2

<em>New Equation {Changed by Adding 12 to Both Sides} :</em>
3x ≥ 5x + 14

Now we subtract 5x from both sides of the equation to get rid of the 5x from the right side.

<em>Old Equation :</em>
3x ≥ 5x + 14

<em>New Equation {Changed by Subtracting 5x From Both Sides} :</em>
-2x ≥ 14

Now we must inverse the inequality. To do that we multiply both sides by -1.

<em>Old Equation :</em>
-2x ≥ 14

<em>New Equation {Changed by Inverse} :</em>
2x ≤ -14

Just by looking at the equation, you can easily tell that it needs to be simplified. So, that's what we'll do next.

<em>Old Equation :</em>
2x ≤ -14

<em>New Equation {Changed by Dividing Both Sides by Two} :</em>
x ≤ -7

Seeing as the equation cannot be simplified any further, we have our answer.
<em>The value of x in the inequality </em><span><em>of 3 ( x – 4 ) ≥ 5x + 2, is </em> x </span>≤ -7.

Hope this helps!
