Step-by-step explanation: trust

The approximate soluton of the equation 102x + 11 = (x + 6)² – 2 is 0.6. Then the correct option is E.

It is a polynomial that is equal to zero. Polynomial of variable power 2, 1, and 0 terms are there. Any equation having one term in which the power of the variable is a maximum of 2 then it is called a quadratic equation.

The quadratic equation is given below.

102x + 11 = (x + 6)² – 2

Open square, we have

       102x + 11 = x² + 12x + 36 – 2

x² – 90x + 23 = 0

By the formula, we have  the value of x

[tex]x = \dfrac{-b \pm \sqrt{b^2 - 4ac}}{2a}\\\\x = \dfrac{90 \pm \sqrt{(-90)^2}-4*1*23}{2*1}\\\\x = 89.74, 0.256[/tex]

The approximate soluton of the equation 102x + 11 = (x + 6)² – 2 is 0.6. Then the correct option is E.

Step-by-step , explanation:

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

Explanation:

"six subtracted from x" translates to "x-6"

So the word problem updates to "x-6 is less than -15"

Then we replace the "is less than" with "<" without quotes.

---------

Extra info: If you want to solve for x, then we add 6 to both sides like so

x-6 < -15

x-6+6 < -15+6

x+0 < -9

x < -9

So any number smaller than -9 will work in place of x.

[tex]a_n=100 \left(\dfrac15\right)^{n-1}[/tex]

Step-by-step explanation:

General equation of geometric sequence:  [tex]a_n=ar^{n-1}[/tex]

Given:

[tex]\implies a_1=a=100[/tex]

[tex]\implies a_2=100 \cdot r=20[/tex]

[tex]\implies a_3=100 \cdot r^2=4[/tex]

Common ratio:

[tex]r=\dfrac{a_3}{a_2}=\dfrac{4}{20}=\dfrac15[/tex]

Therefore:

[tex]a_n=100 \left(\dfrac15\right)^{n-1}[/tex]

Step-by-step explanation:

To see which amount of tickets is the best deal, look at the unit price of each.

To do this, divide the cost of the tickets by the number of tickets to see how much money a single ticket costs in each of the deals.

A) Buying 25 tickets for $10.00 offers the best deal because each ticket is only worth $.40, compared to the other deals where each ticket is worth $.50 or $.42.

B) Usually, businesses offer a better discount the more of a good someone buys due to marketing purposes. I would suggest that the students make the discount higher as the number of tickets increases. Therefore, more people would be willing to buy more tickets and both the consumer and seller will be happy because more discounts (consumer = happy) and more profit (more ticket sales -> business = happy).

Answer: 23

Step-step by explanation:

w(w+4)=437

w^2+4w-437=0

(w+23)(w-19)=0

w=19,-23

w<19

l<23!!

The possible integral width of the rectangle is 23.

A rectangle is a quadrilateral having four sides and the sum of the angles is 180 in the rectangle the opposite two sides are equal and parallel and the two sides are at 90-degree angles.

Given that the length of a rectangle is 4 centimeters is longer than its width. The area of the rectangle is less than 437 square centimeters

The width of the rectangle will be calculated as below:-

w(w+4)=437

w²+4w-437=0

(w+23)(w-19)=0

w=19,-23

w <19

w < 23

Therefore, the possible integral width of the rectangle is 23.

Answer:

The answer is: x < 2.4

Step-by-step explanation:

5x < 12

If we divide both sides by 5, we get an equation like this:

x < 12/5

Then we can convert that fraction to a decimal and we get this!

x < 2.4

Finally, in order to draw it on the number line, we need to do this:

Find 2.4 on the number line, then draw an open circle on that 2.4. Then, attach an arrow going from that circle all the way to the left of the number line! The circle and arrow represents the fact that "x" is not equal to 2.4, but it is smaller. If it was equal to 2.4 or smaller, then the open dot would have to be a closed dot!!!!
