Andre calculated 657÷3 using a method that was different from Elena’s. Explain the following:

Andre subtracted 600 from 657. What does the 600 represent?
Andre wrote 10 above the 200, and then subtracted 30 from 57. How is the 30 related to the 10?
What do the numbers 200, 10, and 9 represent?
What is the meaning of the 0 at the bottom of Andre’s work?

B I believe because it is turning about the origin switching signs

Answer:

Step-by-step explanation:

f(n)=30n

domain all real numbers

range all real numbers

I think.

Domain is {0, 1, 2, 3, ...} and range is {0, 30, 60, 90, ...} for function p=30n.

A relation is a function if it has only One y-value for each x-value.

The function that relates the total number of minutes practiced, p, to the number of practice days, n, is given by:

p = 30n

where 30 is the number of minutes Elena practices each day.

Since we cannot have negative practice days, the domain of the function is the set of non-negative integers:

Domain: {0, 1, 2, 3, ...}

The range of this function is the set of all possible values of p that can be obtained by plugging in values of n from the domain.

In this case, since the function only outputs non-negative values, the range is the set of non-negative integers:

Range: {0, 30, 60, 90, ...}

Hence, Domain is {0, 1, 2, 3, ...} and range is {0, 30, 60, 90, ...} for function p=30n.

Answer:

Step-by-step explanation:

Pythagorean theorem, the well-known geometric theorem that the sum of the squares on the legs of a right triangle is equal to the square on the hypotenuse (the side opposite the right angle)—or, in familiar algebraic notation, a2 + b2 = c2.

Answer:

yes

Step-by-step explanation:

It is true

Answer:

Yes

Step-by-step explanation:

1,4 the first coordinate is X and the second is Y so it means y = 4 and X = 1

So that means the equation becomes 4 = 4 times 1 which is correct since 4 times 1 is 4 and 4=4
