how would I turn 8x- 4y = 16 into y=mx+b form​

Answers

Answer 1

Answer: y=2x-4

Step-by-step explanation:

8x-4y=16 subtract 8x from both sides

-4y=-8x+16 now divide -4 by both sides

y=2x-4

Answer 2

Answer:

y = 2x - 4

Step-by-step explanation:

First divide everything by 4:

2x - y = 4

Then rearrange the equation to get:

y = 2x - 4

Answers

Answer:

first you need to set up the equation which is 20+2x=44 then isolate 2x by doing the inverse operation for 20 which is -20 and add them to both sides which would now give you 2x=24 so divde 24 by 2 which is 12, x=12 answer 12ml

7x - [5 + (3x - 2)] = x - (4x - 5) + (2x - 1)

Answers

Answer:

x = 7/5

I hope this helps

Step-by-step explanation:

7x - [5 + (3x - 2)] = x - (4x - 5) + (2x - 1)

7x - 5 -3x +2 = x -4x +5 +2x -1

4x -3 = -x +4

4x +x = 4+3

5x = 7

x = 7/5

A fair coin was flipped 50 times. It landed on heads 29 times.
What is the experimental probability that the coin landed on tails?

Answers

Answer:

21/50, 42%

Step-by-step explanation:

The total times the coin was flipped is 50 and the number of times it landed on tails is 50-29=21. So we need to divide 21 by 50, which gives us 42%.

It is to be determined Which of these purchases is more likely to be paid for with a credit card
Parking fee  B. Engine repair  C. Soda   D. Lotto ticket


What are credit cards and their uses?

A credit card is a kind of credit service, delivered by banks that permit customers to borrow money within a pre-approved credit limit. It allows customers to make purchase transactions on goods and services.


Since option A, C and D can be omitted because, on parking fee, lotto ticket and soda spending through credit card can be possible but more likely because the spending on these items are very less and service provider do not intentionally accept the credit card
But engine repair is most likely to be paid from the credit card, because the liquidity in the business is very much high comparatively.

Thus, B. Engine Repair is more likely to be paid for with a credit card. Option B is correct

There are two questions :v

Answers

Answer:

Step-by-step explanation:

One

v^2 - 16

This formation is called the difference of squares. That's because there are 2 squares v^2 and 16. The key to this question is the minus sign.

The square root of v^2 = v

The square root of 16 = 4

You get (v + 4)(v - 4)

Let's see what happens when you expand it.

v*v = v^2v*(-4) = - 4vv*(4) = 4v4*-4 = - 16

Look what happens when you add these 4 terms together.

v^2 - 4v + 4v - 16v^2 - 16

is what is left. The two middle terms cancel out.

Two

This one is a perfect square

w^2 + 16w + 64

(w + 8)(w + 8)

Notice both factors are the same. You might wonder how I new that.

w^2 is a perfect square so take the square root.  ....   v      

64 is a perfect square so take the square root    .....    8

Now you have to work backwards to see if it is right.

w*w = w^2w*8 = 8w8*w = 8w8^2 = 64

Adding you get w^2 + 16w + 64 which is what you started with.

Given:

The table of values.

v and x are in direct proportion.

To find:

The formula connecting v and x.

Solution:

(a)

v and x are in direct proportion.

[tex]v\propto x[/tex]

[tex]v=kx[/tex]            ...(i)

Where, k is the constant of proportionality.

Putting v=13.6 and x=32.64, we get

[tex]13.6=k(32.64)[/tex]

[tex]\dfrac{13.6}{32.64}=k[/tex]

[tex]\dfrac{5}{12}=k[/tex]

Putting the value of k in (i), we get

[tex]v=\dfrac{5}{12}x[/tex]

Therefore, the required formula that connecting v and x is [tex]v=\dfrac{5}{12}x[/tex].

(b)

Putting v=n and x=8.16, we get

[tex]n=\dfrac{5}{12}(8.16)[/tex]

[tex]n=3.4[/tex]

Therefore, the value of n is 3.4.
