Step-by-step explanation:
2/5+2/4 (find common denominator)
The common denominator is 20
2/5 is 8/20 (multiply by 4)
2/4 is 10/20 (multiply by 5)
8/20+10/20 is 18/20
If you simplify 18/20 this would by 9/10 if you divide by 2
so the total is 18/20 or 9/10 simplified
Hope this helps!!!!
Have a nice day :)
The transformation from f(x) to g(x) is a vertical stretch by a factor of m
<h3>How to determine the transformation?</h3>
The functions are given as:
f(x) = x
g(x) = mx
Substitute f(x) = x in g(x) = mx
g(x) = mf(x)
From the question, we understand that:
m > 1
This means that;
The transformation from f(x) to g(x) is a vertical stretch by a factor of m

Well the real answer is three hundred-ninety three point five. So numbers around it could be three hundred and fifty and four hundred. An estimate could be three hundred and seventy five.
Answer: 258
Step-by-step explanation:
Since, the sum of GP is,
where r is the common ratio,
a is the first term,
n is the number of term,
Here, series is, 6, -12, 24, -48, _ _ _ _
Which is a GP ( Because there is common ratio in the given consecutive terms )
So, for the above series, a = 6, r = 
and n = 7,
⇒ 
⇒ 
⇒ 
⇒ 
Thus, the sum of the 7 terms of the given series is 258.
