Answer:
2.5
Step-by-step explanation:
a = 1
b = 5
ab
= 1 x 5
= 5
0.5b
= 0.5 x 5
= 2.5
ab - 0.5b
= 5 - 2.5
= 2.5
Answer:
x=1
Step-by-step explanation:
x+3x+5x+7x+...+49x=625
(1+3+5+7+...+49)x=625 (1)
now consider s= 1+3+5+7+...+49
a=1
d=3-1=2
l=49
l=a+(n-1)d
49=1+(n-1)2
49-1=(n-1)2
48/2=n-1
n-1=24
n=24+1=25
s=n/2*(a+l)
s=25/2(1+49)
x=25/2×50
s=25×25=625
from (1)
625 x=625
x=625/625=1
I think it would be 50/50. But I'm not entirely sure.
A graph is a function if there is only one X value for any Y value.
Since the graph is in the shape of a U, there can only be one X for every Y value, so this graph is a function.
The answer is C.
