Answer:
C. Starting with a given set of rules and figuring out what must be true
. TRUE
Step by step explanation:
Mathematical Induction
Mathematical Induction is a mathematical technique which we can use to prove any given mathematical statement, result, theorem or corollary with help of induction.
Here, we assume the statement to be true for a smaller natural number (Usually 1) and then prove the statement to be true for ANY ARBITRARY NUMBER say k.
Now, from the given options:
A. Writing down the steps to solve a complicated math problem
.
FALSE as the induction method is based on ASSUMPTION and INDUCTION.
B. Forming rules based upon observations and experiences
.
FALSE as the induction method is based on ASSUMPTION and INDUCTION. We need to induce the needed statement or Result.
C. Starting with a given set of rules and figuring out what must be true
.
TRUE as the induction method is based on ASSUMPTION and INDUCTION.
We try and find out the result with the given existing data.
D. Reducing the solution to a problem in lowest terms.
FALSE as the induction method is based on ASSUMPTION and INDUCTION.
We just need to add the 2 numbers together to find the balance at the end of Wednesday.
-90+100
=10
She had $10 at the end of Wednesday in her bank account.
The lines are intersected at point (0, -5). So (0, -5) is the solution.
Answer is the third one
(0,-5 )
Try it like this. it may help: Make it like a rainbow. Find out what all can go into 8 and 14. So kinda like this.
1,2 4 ,8
then just connect it, like a rainbow, hence the name.
Hope that helped!
As shown in the model below, there are three lines.
