The multiplicative inverse of -2/5 is -5/2
Answer:
2/3
Step-by-step explanation:
2/15 of 5
Of means multiply
2/15 * 5
Multiply the numerators
2*5 = 10
Put over the denominator
10/15
We can divide the top and bottom by 5
10/5 =2
15/5 =3
2/3
The answer is 6.
Absolute value works like this:
If you have just a number inside the bars, then it's positive. If the negative sign is inside the bars, it's still positive. If the negative sign is outside the bars, regardless of what's inside the bars, then it's negative.
Basically, you are adding, because absolute values are positive, unless you have a minus sign outside the absolute value, so 6+5=11.
What you do is this:
y = |x - 5|
y = x + 5
y = 11 + 5
y = 6
Answer:
yes
Step-by-step explanation:
If the sequence is geometric then the common ratio r between consecutive terms will be equal.
= - 2
= - 2
= - 2
The common ratio between terms = - 2
Hence the sequence is geometric
