Answer:

C

Step-by-step explanation:

Given the 2 equations

3x + 4y = 8 → (1)

y - 5x = 2 ← rewrite as

- 5x + y = 2 → (2)

Multiplying (2) by - 4 and adding to (1) will eliminate the y- term

20x - 4y = - 8 → (3)

Add (1) and (3) term by term to eliminate y

23x + 0 = 0

23x = 0 , then

x = 0

Substitute x = 0 into either of the 2 equations and solve for y

Substituting into (1)

3(0) + 4y = 8

4y = 8 ( divide both sides by 4 )

y = 2

solution is (0, 2 )

That is the lines intersect once at (0, 2 )

For 3x + 4y = 8

X-intercepts: (8/3, 0

y-intercepts: (0,2)

____________________

For y- 5x = 2

X-intercepts: (-2/5, 0)

y-intercepts: (0,2)

_______________________________

Your answer is C

_________________

To find the X-intercept, substitute in 0 for y and solve for x. To find y-intercept,substitute in 0 for x and solve y.

Hope this helps

Vivi is a drummer for a band. She burns 756 calories while drumming for 3 hours. She burns the same
german

The question you asked uses the concept of division, something that a bit tricky at first but gets easier as you master it!

So first let’s write and equation for your problem:

Let x = the amount of calories she burns each hour.

So we already know that Vivi was drumming for 3 hours, that she burned 756 calories, and that she burned the same amount of calories each hour.

Since she burned 756 calories in total, we know that the equation will have to equal 756:

= 756

We also know that the answer will be 3(hours) times x(the amount of calories), so now we just plug it into the equation:

3x = 756

To find what ‘x’ equals we have to divide both side by 3:

3x/3 = 756/3

Now all we have to do is simplify and you have your answer!

x = 252

And there you have it, Vivi burned 25 calories per hour!

Hope this helps! :)

What is the fractional equivalent of 0.2323...? 23/99 23/999 2/9
lana [24]
It is equivalent to 23/99 but not for the rest.

As the denominator gets larger, the decimals gets smaller.
eg. 23/999 = 0.023232323...

As you can see , it is 0.02 now so it is not equivalent to 0.232323 as it is 0.2
