Answer:
y=2x+3
Step-by-step explanation:
in third line x = 0 y=2×0+3 =3
We can use triangle inequality to prove it. What this rule is, it's basically if u add up 2 sides of the triangle, the length must be longer than the third side, check all 3 sides, and if all sides matches with the rule, a triangle is possible.
The data cannot be modeled by a linear equation because the rate of change is not constant. This can be seen in the fact that when you increase x from 1 to 2, you subtract 3 from the y-values. However, as you add 2 more, you continue to subtract 3 from the y-values. If the function were a linear function, we would likely subtract 6 from the y-values, since that would form a constant ratio.
You can even look at the fact that as we increased the x by 4, we continued to decrease the y by 3. This does not form a constant ratio, and is thus the data could not be modeled by a linear function.
Answer:
62.5 interest on 2500 loan
Step-by-step explanation:
Given that,
amount of loan bank has granted = 2500
number of years = 90 days
90 days = 3 month
3 months = 1/4 year = 0.25 year
interest rate = 10%
= 10 / 100
= 0.1
Formula to use
Principal * interest rate expressed as a decimal * time in years
2500 * 0.1 * 0.25
62.5
Hence, the interest on the loan of 2500 with 10% interest rate for 90 days is 62.5
