What is the correct equation in vertex form for x^2+4x-12=0

Answer:

The correct counterexample is [tex]b \leq 6[/tex].

Step-by-step explanation:

We proceed to demonstrate the validity of given implication by direct demonstration and use of our knowledge in algebra:

1) [tex]a + b \leq 8[/tex] Given.

2) [tex]a = 2[/tex] Given.

3) [tex]2+b \leq 8[/tex] 2) in 1)

4) [tex]2 + b +(-2) \leq 8 +(-2)[/tex] Compatibility with addition.

5) [tex]b+[2+(-2)]\leq 6[/tex] Commutative and associative properties/Definition of subtraction

6) [tex]b \leq 6[/tex] Existence of additive inverse/Modulative property/Result.

This contradicts what implies the given proposition. The correct counterexample is [tex]b \leq 6[/tex].

Answer:

Hello! your answer should be 2 :)

Step-by-step explanation:

the simpliest way to look at multipicaton is just complex addition, so, for example, 10x3 is the same as 10+10+10. so for your question, we'll just add 6 to itself until we get to twelve! 6x1=6, 6x2=12, nice and simple, there's your answer! :)

She need to multiply by 2 next.

A number system is defined as a system of writing to express numbers. It is the mathematical notation for representing numbers of a given set by using digits or other symbols in a consistent manner.

Alex wants to multiply the number with 12.

She multiples by 6 first.

So, we need to focus on that what can be multiply by 6 to get 12 or what will be the quotient dividing 12 by 6.

Both of the above will tell us what will be next number.

So,

6*2=12

or, 12/6=2

In both situation we get 2.

Hence, she need to multiply by 2 next.

Answer:

-$15

Step-by-step explanation:

To find the average yearly change, divide -120 by 8, since it has decreased by $120 over 8 years.

-120/8

= -15

So, the average yearly change in the value of the card is -$15

Answer:

$120/8= $15 in a year.

15 times 8 is 120.

Answer:

For 6 chairs, 72 screws and for 9 chairs, 108 screws.

Step-by-step explanation:

So, for every 2 chairs, he needs 24 screws.

By Unitary Method,

We get screws needed for one chair, that is, 24/2 = 12 screws for one chair.

So, for 6 chairs,

Similarly, for 9 chairs,

Answer:

The ratios to this would be:

[tex]\left[\begin{array}{ccc}2&24\\6&72\\9&108\end{array}\right][/tex]

Step-by-step explanation:

Ratios are similar to fractions, in some ways, ratios are to show the relation between two numbers, such like a proportion:

For example:

4:3

or the ratio of men' jobs to women's' is 8 to 1 (8:1)

In this case, it is said that:

Gary needs 24 screws for every 2 chairs.

The ratio of this is 24: 2

Also meaning:

[tex]\frac{24}{2}[/tex]

and [tex]2\sqrt{24}[/tex], the quotient is = 13

Now we multiply 12 to '6' and '9'

You will get:

12(6) = 72

12(9) = 108

This will be your answer.

Thanks for watching buddy good luck.

Answer:

y = mx + b

where,

y = earning

m = slope or earning per hour = $24

x = total number of hours

b = y intercept or initial earning upon visit = $45

Hence,

y = 24x + 45

Since we are working at two separate work sites, therefore each site we must earn 810/2 = 405

So when y = 405:

405 = 24x + 45

x = 15 hours

So you must work 15 hours at each site.

Step-by-step explanation:

Answer:

7.56 hours.

Step-by-step explanation:

So my equation will be:

$45 + $24h

If we need to find out how many hours you have to work in order to earn $117 working at two separate work sites, the equation would look like this:

45 + 25h ÷ 2 = 117.

First we need to multiply both sides of th equation by 2.

[tex]\frac{2\left(45+25h\right)}{2}=117\cdot \:2[/tex]

Then, I had to simplify.

[tex]5+25h=234[/tex]

After simplifying, it was about time to subtract 45 from both sides of the equation.

[tex]45+25h-45=234-45[/tex]

I had to simplify again, then divide both sides by 25.

[tex]25h=189[/tex]

[tex]\frac{25h}{25}=\frac{189}{25}[/tex]

Again, I have to simplify for a final time to get the answer of..

[tex]h=\frac{189}{25}[/tex]

In decimal form, thats equal to 7.56 hours.

h = 7.56.

Step-by-step explanation:

First you divide 325 by 5. And you get 65 which is how many miles per hour she went. Then you can put it in a unit converter to change miles per hour to feet per second. And it should be 95.33 (sorry for my lack of a detailed explanation of how to transform miles per hour into feet per second)

Answer:

[tex]-9.31x^2+56.26x[/tex]

Step-by-step explanation:

Let the quadratic function be:

[tex]h=ax^2+bx+c[/tex]

Where [tex]h[/tex] is the height of soccer ball and

[tex]x[/tex] is the time in seconds.

Initially, at time [tex]x=0\Rightarrow h=0[/tex]

Therefore, [tex]c=0[/tex]

Given that,

[tex]x=3, h=85\\and\\x=6, h=2.5[/tex]

Putting the values and making equations in [tex]a,b[/tex] :

[tex]85=9a+3b\\2.5=36a+6b[/tex]

By solving the above equations, we get:

[tex]a=-9.31\\ and\\b =56.26[/tex]

So, the quadratic expression is:

[tex]-9.31x^2+56.26x[/tex]
