If 2 graphs meet at the same point means that for the same x both function give the same outcome/value y. That's why they are equal. Suppose f(x) = x^2 -1 and g(x) = 2x-1. This function meet at the point x=2(the point of intersection). Let's put the value of intersection in the functions. f=2^2-1=3, g= 2*2-1=3, we proved in another way why that's the point where 2 graphs are equal each other.
Answer:Yes, Naomi is incorrect.
Explanation: For explain this we can consider an example - Let us suppose Naomi deposited 100 rupees in her saving account at the rate 6% for 1 year .
Now, if the interest is quarterly then according to the formula
compound interest =
-P where r is the rate annually and n is the number of years.
so CI=
-100 ( here the rate is already given in quarterly)
CI=
-100= 1.26247696-100=26.247696 rupees=26(approx)
Now, if the compound interest is 1.25 per month then again from the formula-
CI=
-P
CI=
-100= 100(1.16075452)-100=16.075452=16(approx)
Answer:
g(- 3) = - 27
Step-by-step explanation:
To evaluate g(- 3) substitute x = - 3 into g(x)
g(- 3) = - 2(- 3)² + 3(- 3) = - 2(9) - 9 = - 18 - 9 = - 27
Answer:
2km 379m
Step-by-step explanation:
If you add the 529 meters more that Allison rode to 850 meters it adds up to 1379 meters which is 1 kilometer and 379 meters, and then you add the kilometer to it and its a total of 2 kilometers and 379 meters
The company paid $2000 for the printer
Step-by-step explanation:
Let x be the price of the printer for which the company bought it.
If x is the price of printer, then 25% of x will be the profit made by the company.
That is:
0.25x
According to the statement,
The cost and profit earned by company are equal to 2500
So,

Dividing both sides by 1.25

Hence,
The company paid $2000 for the printer
