Answer:
(x, y) = (2/5, 1)
Step-by-step explanation:
Substitute for y and solve for x.
1 = -5x +3
-2 = -5x . . . . . . subtract 3
2/5 = x . . . . . . divide by -5
The solution is (x, y) = (2/5, 1).
Answer:
x^2-3x+2
Step-by-step explanation:
distribute and combine like terms
The rule for sequence is:

Step-by-step explanation:
To write the function rule, we have to check first whether it is an arithmetic sequence or geometric sequence
So
We have to find the common difference first. Common difference is the difference between two consecutive terms of a arithmetic sequence.
So,
Here

The common difference is same so the sequence is an arithmetic sequence.
The explicit formula for an arithmetic sequence is:

Putting the values of d and a_1 we get,

Hence,
The rule for sequence is:

Answer:
<h2>
40.1 cm</h2>
solution,
BC=8.4 cm
AB=12 cm
BD=4.1 cm
We have to find out: AC ,CD
using Pythagoras theorem:
In ∆ABC ,<B=90°

Similarly,
In ∆BCD, CB=90


Perimeter:
AC+CD+AD
=14.64+9.34+(12+4.1)
=40.08
= 40.1 cm
Hope this helps...
Good luck on your assignment..
