the answer I knew but I forgot at ate
Answer:
1.) - 1/2
2.) the slope is 0 which means it is a vertical line
Step-by-step explanation:
In order to solve this you take the formula
y-y / x-x
and put they y value and x value of each equation in
Answer:
= 1
Step-by-step explanation:
The n th term of an arithmetic progression is
= a + (n - 1)d
where a is the first term and d the common difference
use the 9 th term and 7 th term to find a and d
= a + 8d = 
→ (1)
= a + 6d = 
→ (2)
Subtract (2) from (1) term by term
2d = 
⇒ d = 
Substitute this value into (2) and solve for a
a + 
=
a = - =
Hence
= + 
= 1
Answer:
It's C
Step-by-step explanation:
Correct me if i'm wrong.
But it seems to make sense with my calculations....
Hey there,
Let's say that the first piece is x cm
1st = x
2nd = x + 25%
3rd = x - 25%
100% = 240 cm
1% = 240 / 100
= 2.4cm
x + x + 25 + x - 25 = 100
3x + 25 - 25 = 100
3x = 100 - 25 + 25
3x = 100
3x = 240 cm
x = 240 / 3
= 80 cm
1st piece = 80 cm
2nd piece = 80 + (25% x 80)
= 80 + 20
= 100cm
3rd piece = 80 cm - (25% x 80)
= 80 cm - 20
= 60cm
Hope this helps :))
