Answer: A) Multiply both sides of the top equation by 2.

Step-by-step explanation: The x-coefficient of the first equation (the number that is next to the x) is 4, and the x-coefficient of the second equation is 8, in order to them to be equal, we need to multiply the first equation by 2 (both sides), so the correct answer is the corresponding to option A, the equations would be:

8x+4y=8 first equation (after multiply it by 2)

8x-y=18 second equation

<u>The answer is A. Multiply both sides of the top equation by 2</u>

So since we know that 4 × 2 = 8, it would only make sense to multiply both sides by 2 so that the top equation has the x coefficient be 8.

(9,-1); m=4/3 write an equation in point slope form for the line through the given point with the given slope
madreJ [45]
For this problem you are going to need to know the point-slope equation which is: 
y-y₁=m(x-x₁)

Now, m=slope and the x and y values are given to us already, so now we just plug our variables into the formula.

It should look like this: y+1= \frac{4}{3}(x-9)
Since all they are asking for is for you to put it into a formula this will be your answer.

Any number is divisible by 2 is also divisible by 6 find a counter example to show that conjecture is false
likoan [24]

Answer:

  2

Step-by-step explanation:

  To be divisible by 6, an even number must also be divisible by 3. Two of every three even numbers are <em>not</em> divisible by 3, so are not divisible by 6.
