How to factorise this?!
4x-14xy

Answers

Answer 1
Answer: Find the highest common factor, which is 2X, therefore, this goes outside of the bracket. So inside goes 4x/2x= 2 & 14xy/2x= 7y2x(2-7y)When you multiply out of the brackets, everything should be equal
Answer 2
Answer: Take a factor of x out of the equation:
2x(2-7y)

What’s the difference between an event and in event handler

Answers

Answer:

There’s a subtle, but important difference between these 2 methods of handling events. If you’ll use the first method, event handlers, the difference is that if you add two event handlers for the same button click, the second event handler will overwrite the first and only that event will trigger

Am I corectWhat is the fraction 8/36 expressed in lowest terms? I got 2/9 thats my final answer

Answers

I'm going to say yes. But just check.   (8)/(36) can both be divided by 4. So when divided you get (2)/(9) and 2 can't go into 9, so yes that is your lowest term.

Express 0.68888888888.... as a rational number.

Answers

Answer:

688/999.

Step-by-step explanation:

To express the repeating decimal 0.68888888888... as a rational number, you can set it up as an equation and solve for the fraction.

Let x = 0.68888888888...

Now, we want to remove the repeating part by multiplying x by an appropriate power of 10. In this case, we'll multiply by 10 to the power of the number of decimal places in the repeating part:

1000x = 688.88888888...

Now, we'll subtract x from 1000x to eliminate the repeating part:

1000x - x = 688.88888888... - 0.68888888888...

999x = 688

Now, divide both sides by 999 to isolate x:

x = 688 / 999

So, the repeating decimal 0.68888888888... can be expressed as the rational number 688/999.

6.5 was added to a certain number. This sum was then divided by 13.6. Finally, the quotient was multiplied by 5. This product came out to 5. What was the number

Answers

Answer:

7.1

Step-by-step explanation:

Here's how we have to set this up.  We will start with the first statement, which algebraically looks like this:

x + 6.5 = y (since we don't know what x is, we don't know what the sum of x and 6.5 is.  We will call that new number y.)

Next, we are dividing that sum, y, by 13.6:

(y)/(13.6)=z (again, since we don't know what y is, we don't know what y divided by 13.6 is.  We will call that new number z.)

Finally, the quotient, z, is multiplied by 5:

5z

Now we work backwards, subbing in our unknowns, one at a time.  

5z

If z = (y)/(13.6), we sub it into the expression 5z:

5((y)/(13.6)) and

if y = x + 6.5 we plug that in for y:

5((x+6.5)/(13.6))=5 since we know that whole mess is equal to 5.  NOw we solve for x, the original number.  Begin by dividing both sides by 5 to get:

(x+6.5)/(13.6)=1

Now multiply both sides by 13.6 to get:

x + 6.5 = 13.6 so

x = 7.1

Check this if you'd like by plugging in the 7.1 for x in the intial equation to solve for y, then plug that into the next equation to solve for z, then see if they're equal (they are, but test it out for yourself).

What is the domain of g?

Answers

Answer:

x≥ -3

Step-by-step explanation:

The domain is the values that x can take

g(x) = sqrt( x+3)

This must be greater than or equal to zero

x+3  must be greater than or equal to zero

x must be greater than or equal to -3

x≥ -3
