Answer:

[tex]m=8x-5-4\Delta x[/tex]

Step-by-step explanation:

We have the function:

[tex]f(x)=4x^2-5x-1[/tex]

And we want to use the difference quotient:

[tex]m=\frac{f(x+\Delta x)-f(x)}{\Delta x}[/tex]

To find the slope function.

So, let's substitute [tex]x+\Delta x[/tex] for our function. This yields:

[tex]m=\frac{(4(x+\Delta x)^2-5(x+\Delta x)-1)-(4x^2-5x-1))}{\Delta x}[/tex]

Let's square. Use the perfect square trinomial pattern. This yields:

[tex]m=\frac{(4(x^2+2x\Delta x-\Delta x^2)-5(x+\Delta x)-1)-(4x^2-5x-1))}{\Delta x}[/tex]

Distribute:

[tex]m=\frac{(4x^2+8x\Delta x-4\Delta x^2-5x-5\Delta x-1)-(4x^2-5x-1)}{\Delta x}[/tex]

Distribute the right:

[tex]m=\frac{(4x^2+8x\Delta x-4\Delta x^2-5x-5\Delta x-1)+(-4x^2+5x+1)}{\Delta x}[/tex]

Combine like terms:

[tex]m=\frac{(4x^2-4x^2)+(-5x+5x)+(1-1)+(8x\Delta x-4\Delta x^2-5\Delta x)}{\Delta x}[/tex]

The first three terms will cancel. This leaves us with:

[tex]m=\frac{8x\Delta x-4\Delta x^2-5\Delta x}{\Delta x}[/tex]

We can factor out a Δx from the numerator:

[tex]m=\frac{\Delta x(8x-4\Delta x-5)}{\Delta x}[/tex]

The Δx will cancel. So, our slope function is:

[tex]m=8x-5-4\Delta x[/tex]

And we're done!

Answer:

B) by sharing with electrons  

Step-by-step explanation:

Atoms form a new substance by sharing electrons with each other. Covalent bonds are when at least one pair of electrons are shared between atoms. Ionic bonds are when positive and negative bonds attract, which is resulted in sharing an electron.

Answer:

v = [tex]\frac{m}{D}[/tex]

Step-by-step explanation:

Rewrite the equation as [tex]\frac{m}{v}[/tex] = D

[tex]\frac{m}{v}[/tex] = D

Solve for  v.

v = [tex]\frac{m}{D}[/tex]

Answer:

-12

Step-by-step explanation:

10/5 = x-6/x+3

2/1 = x-6/x+3

cross multiply

2(x + 3) = x - 6

2x + 6 = x - 6

collect like terms

2x - x = -6 - 6

x = -12.

Answer:

2x+2

Step-by-step explanation:

First you want to distribute

1/2(2x+4)

ignore the ending +x for now

Distribute 1/2 to 2x

since 2*1/2 is 1 then we get 1x, or x

next distibute 1/2 to 4

you get +2 since 1/2*4=2

so what you end up with is x+2

However, you still have the +x from the beginning

x+2+x

Imagine that each x has a one in front

1x+2+1x

now re arrange so the common factors are near each other

1x+1x+2

now add the common factors

1x+1x=2x

and finally you get 2x+2

Answer:

Marco can multiply both the 0.01 for the centi and the 10 for the deka by 100, making them both, 1 centi = 1,000 deka, therefore 77 centi is 77,000 deka.

Answer:

Your question might have an error :( All inequality equations have to have a inequality symbol somewhere in the equation. Yours dont have one but no worries. I'll see what I can do.

Based on your equation, that is not a inequality, so therefore your answer would have been: (-5x-16)

Step-by-step explanation:

If your equation was:

(-5x-10<-6) your answer would have been: x>-4/5

(-5x-10>-6) your answer would have been: x<-4/5

(-5x>-10-6) your answer would have been: x<16/5

(-5x<10-6) your answer would have been: x>-4/5

Those are all the possible outcomes of that equation :)

Please double check to make sure that is what the question states : )

Answer:

37.92

Step-by-step explanation:

To find the average of something add all of the numbers and then divide by how many numbers there are

31.8 + 43.8 + 29.2 + 31 + 53.8 = 189.6

189.6 ÷ 5 = 37.92

Answer:

37.92

Step-by-step explanation:

31.8 +  43.8 +  29.2 +  31 +  53.8 = 189.6

189.6 ÷ 5 = 37.92

Answer:

The answer to this equation is 7.5

Step-by-step explanation:

What I did is started with PEMDAS:

6÷2 (1 + 2) ÷4 (4 + 5) ÷ 6

          ^               ^

         (3)            (9)

Now the 3 and the 9 are what are in the ()

6÷2 = 3... 3  (3) = 9.

9 ÷ 4 = 5.

The 9 from earlier is still in parenthesis...

Take 5 and the 9 in parenthesis and multiply (If a single number is in (), It means to multiply anyway)

5 (9) = 45

The Final Step is to divide by 6

45 ÷ 6 =  (FINAL) 7.5

I hope this helped! (:

Answer:

[tex]3\frac{3}{8}[/tex]

Step-by-step explanation:

6 ÷ 2(1+2) ÷ 4(4+5) ÷ 6 =​

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

By order of operations, parentheis comes first.

6 ÷ 2*(1+2) ÷ 4*(4+5) ÷ 6 =​

6 ÷ 2*(3) ÷ 4*(9) ÷ 6=

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

Next comes multiplication and division. Now, we can remove  the parentheis and solve from left to right.

6 ÷ 2*(3) ÷ 4*(9) ÷ 6=

6 ÷ 2*3 ÷ 4*9 ÷ 6=

3*3 ÷ 4*9 ÷ 6=

9 ÷ 4*9 ÷ 6=

27/8=

Answer:

Benito's line has a slope of three

Step-by-step explanation:

Slope can be determined by the rate of change. Because Benito's first point is 0,1 that means that x = 0 and y = -1. Benito's second point is 1,2 which means that x = 1 and y = 2. To determine the slope, you need to look at the change of y. We can see that y=-1 in the first point, and y=2 in the second point. This is an increase of three, which means that Benito's line has a slope of three.

Answer: Benito:On a coordinate plane, a line goes through points

(0, negative 1) and (1, 2).
