Explanation:
This can be explained by thinking numbers on the number line as:
Lets take we have to multiply a positive number (say, 2) with a negative number say (-3)
<u>2×(-3)</u>
Suppose someone is standing at 0 on the number line and to go to cover -3 , the person moves 3 units in the left hand side. Since, we have to compute for 2×(-3), The person has to cover the same distance twice. At last, he will be standing at -6, which is a negative number.
A image is shown below to represent the same.
<u>Thus, a positive times a negative is a negative number.</u>
They are equivalent
30:12 => 5:2
40:16 => 5:2
hope this helsp
2 and 14/15
Because the first step of subtraction is common denominators
This answer would be true. I believe. It would be that because they are completely separate.
-5 is for f(x)=x+5
4 is for g(x)=x-4
Hope this helps!!
