If (8,0) is on y=bx+x^2, what is the least value of the function?

Answers

Greetings from Brasil...

(8; 0) ⇔ (X; Y) ⇒ so, according to the statement of the question, when X = 8 we have a Y = 0.

Y = bX + X²

(8; 0) ⇒ X = 8 and Y = 0

0 = b · 8 + 8²

0 = 8b + 64

8b = - 64

b = - 64/8

b = - 8

Then

Y = X² - 8X

The minimum value or least value of the function is -16 at x = 4 after plotting the graph.

What is a quadratic equation?

Any equation of the form [tex]\rm ax^2+bx+c=0[/tex] where x is variable and a, b, and c are any real numbers where a ≠ 0 is called a quadratic equation.

As we know, the formula for the roots of the quadratic equation is given by:

[tex]\rm x = \dfrac{-b \pm\sqrt{b^2-4ac}}{2a}[/tex]

We have:

(8,0) is on y=bx+x²

Plug x = 8 and y = 0

0 = 8b + 64

b = -8

y = -8x + x²

Thus, the minimum value or least value of the function is -16 at x = 4 after plotting the graph.

Step-by-step explanation:

Below you will find the question is broken down into two parts. The first is asking you to solve equations and show your work. The second is asking you to check someone else’s work. Please read instructions and make sure to complete all components. Solve the following equations, show your work for each equation in the three empty boxes below x+2=5 2n+5=n c.5(x+2)-7=3x+5 a) b) c)

Answers

Step-by-step explanation:

Equation (1) is :

x+2=5

Subtract 2 from both sides,

x+2-2=5-2

x=3

Equation (2) is :

2n+5=n

Taking like terms together,

2n-n=-5

n=-5

Equation (3) is :

5(x+2)-7=3x+5

⇒5x+10-7=3x+5

taking like terms together,

5x-3x=5-10+7

⇒2x=2

x=1

Hence, x =3, n = -5 and x = 1 is the required answer.

A student wants to buy 4 bottles of lemonade that cost $1.65 each . if they pay with a bill how much will they get back?

Answers

Answer:

$3.40

Step-by-step explanation:

"A bill" = "1 bill"

Possibile bills = $1, $5, $10, $20, $50, $100

4 × 1.65 = 6.6

$6.60 is more than $5, but less than $10

Since the student is only using a single bill, it must be the $10 bill

10 - 6.6 = 3.4

$3.40

b. 7x + 13.4y
c. -11x + 13.4 y
d. 7x + 2.8y

Answers

Answer:

Step-by-step explanation:

We have the expression:

[tex](-2x+8.1y)-(-9x+5.3y)[/tex]

First, let's distribute the negative on the right. This gives us:

[tex]=(-2x+8.1y)+(9x-5.3y)[/tex]

Now, let's combine like terms:

[tex]=(-2x+9x)+(8.1y-5.3y)[/tex]

Add:

[tex]=(7x)+(8.1y-5.3y)[/tex]

Subtract:

[tex]=(7x)+(2.8y)[/tex]

Simplify:

[tex]=7x+2.8y[/tex]

So, our answer is D.

And we're done!

Answer:

d. 7x + 2.8y

Step-by-step explanation:

You have to combine like factors to solve. Distribute before solving.

(-2x + 8.1y) - (-9x + 5.3y)

-2x + 8.1y + 9x - 5.3y

7x + 8.1y - 5.3y

7x + 2.8y

Mathematically derive a set of values for b and c such that the interval [0, 10] represents the solution to the inequality |x−b| <= c.

Answers

Answer: Ix - 5I ≥ 5.

Step-by-step explanation:

We want the set:

[0, 10]

to be the solution of:

Ix - bI ≤ c

So we need to find the values of c and b.

The first step is to find the middle point in our segment.

We can do that by adding the extremes and dividing it by 2.

M = (10 + 0)/2 = 5

And we also want to find half of the difference between the extremes, this is:

D = (10 - 0)/2 = 5.

Now, this set will be the set of solutions of:

Ix - MI ≥ D

Then in our case, we have:

Ix - 5I ≥ 5.

so we have that b = 5, and c = 5.

Determine whether the absolute value of a difference is sometimes, always, or never the same as the difference of the absolute values.

Ia-bI = IaI - IbI

Answers

Answer: Sometimes True

=====================================================

Explanation:

Let's see what happens when a = b

Let's pick something like a = 2, so b = 2.

|a-b| = |2-2| = |0| = 0

|a|-|b| = |2|-|2| = 2-2 = 0

Both result in 0.

We see that |a-b| = |a|-|b| is true for this example.

The given equation is either "sometimes true" or "always true"

--------------

Now let's pick something where a < b. Let a = 1 and b = 2

|a-b| = |1-2| = |-1| = 1

|a|-|b| = |1|-|2| = 1-2 = -1

We get different results, so |a-b| = |a|-|b| is not true for this example.

So this leads us to say the original equation is sometimes true.

[tex]|a-b| = |a| - |b|[/tex] if and only if [tex]a \ge 0\,\land\,b\ge 0[/tex]. That is, it is sometimes the same.

Absolute Value is a mathematic Form which represents either the Magnitude or the Distance respect to Origin of a given Real Number, whose is depicted below:

[tex]|x| = \left \{ {{x,\,x\ge 0} \atop {-x,\,x< 0}} \right.[/tex], for all [tex]x\in \mathbb{R}[/tex] (1)

In this question we must check if [tex]|a|-|b| = |a - b|[/tex]. Hence, we must check it for the following four cases:

(i) [tex]a \ge 0\,\land\,b\ge 0[/tex]

(ii) [tex]a\ge 0\,\land \,b < 0[/tex]

(iii) [tex]a < 0\,\land\,b<0[/tex]

(iv) [tex]a< 0\,\land b\,\ge 0[/tex]

Case I

1) [tex]|a| \ge 0[/tex], [tex]|b| \ge 0[/tex], [tex]|a-b| \ge 0[/tex] Definition of absolute value.

2) [tex]a \ge 0\,\land\,b\ge 0[/tex] Given.

3) [tex]a - b = a - b[/tex] Definition of absolute value/Reflexive Property

4) [tex]|a-b| = |a| - |b|[/tex] Result.

Case II

1) [tex]|a| \ge 0[/tex], [tex]|b| \ge 0[/tex], [tex]|a-b| \ge 0[/tex] Definition of absolute value.

2) [tex]a\ge 0\,\land \,b < 0[/tex] Given.

3) [tex]a - b =^{?} a - (-b)[/tex] Definition of absolute value.

4) [tex]a - b =^{?} a + b[/tex] [tex]-(-x) = x[/tex]

5) [tex]-b =^{?} b[/tex] Compatibility with addition/Modulative property/Existence of additive inverse/Absurd found.

6) [tex]|a-b| \ne |a| - |b|[/tex] Reductio ad absurdum.

Case III

1) [tex]|a| \ge 0[/tex], [tex]|b| \ge 0[/tex], [tex]|a-b| \ge 0[/tex] Definition of absolute value.

2) [tex]a < 0\,\land\,b<0[/tex] Given.

3) [tex]a-b =^{?} -a-(-b)[/tex] Definition of absolute value.

4) [tex]a-b =^{?} -(a -b)[/tex] [tex](-1)\cdot x = -x[/tex]/Distributive property/Absurd found.

5) [tex]|a-b| \ne |a| - |b|[/tex] Reductio ad absurdum.

Case IV

1) [tex]|a| \ge 0[/tex], [tex]|b| \ge 0[/tex], [tex]|a-b| \ge 0[/tex] Definition of absolute value.

2) [tex]a< 0\,\land b\,\ge 0[/tex] GIven.

3) [tex]a-b =^{?} -a - b[/tex] Definition of absolute value.

4) [tex]a =^{?} -a[/tex] Compatibility with addition/Modulative property/Existence of additive inverse/Absurd found.

5) [tex]|a-b| \ne |a| - |b|[/tex] Reductio ad absurdum.

In a nutshell, [tex]|a-b| = |a| - |b|[/tex] if and only if [tex]a \ge 0\,\land\,b\ge 0[/tex]. That is, it is sometimes the same.
