The coefficients are simply 12, 2, 4, and 7.

Step-by-step explanation:

Coefficients are the numbers that come before terms. Each term has a coefficient before it.

Answer:

The coefficients in the expression are: 12, 2,4 and 7

Step-by-step explanation:

Expressions like this 12xy^{3} +2x^{5}y+4x^{5}x^{2}+7x^{5}y are known as polynomials in two variables.

In a general form a polynomial in two variables is an expression that can be written in the form:

P(x,y) = a_{0,0}+a_{1,0}x+a_{0,1}y+a_{2,0}x^{2}+a_{1,1}xy+a_{0,2}y^{2}+...+a_{n,0}x^{n}+...+a_{0,n}y^{n}, where a_{0,0} or a_{n,0} are called the coefficients.

To get polynomial coefficients, you can take the numbers in front of each terms, for example 12xy^{3} is known as term and the coefficient is 12.

Or compare the general form of a polynomial with the polynomial 12xy^{3} +2x^{5}y+4x^{5}x^{2}+7x^{5}y and you find that the coefficients in the expression are: 12, 2,4 and 7

Suppose c was a total membership cost for m the two equations that model c are c=30m+50 an c=20m+100
Maksim231197 [3]

Answer:

5 months

Step-by-step explanation:

Given

c = 30m + 50

c = 20m + 100

Required [Missing from the question]

At what month will the cost be equal

To do this, we equate both expressions

c = c

This gives:

30m + 50 = 20m + 100

Collect like terms

30m - 20m = 100 - 50

10m = 50\\

Solve for m

m = \frac{50}{10}

m = 5

HACTEHA [7]

Answer:

1/6

Step-by-step explanation:

There are 6 possible outcomes when you roll a die

1,2,3,4,5,6

P(5) = number of outcomes with a 5/ total outcomes

        =1/6
