Answer: 2xy, -xy,\frac{1}{2}xy


Step-by-step explanation:

  • <em>The like terms are the terms that have the same variables and powers. The coefficients do not need to match.</em>

For example :- 9xy and -67xy are like terms since both the expression have the same variables x and y and same exponents.

From the given options, we can see that the expressions 2xy, -xy,\frac{1}{2}xy they have same variables x and y and same exponents.

Rest of others are have no like exponents or variables.

Answer:

  • 2xy
  • -xy
  • 1/2xy

Step-by-step explanation:

Like terms are the terms which have the same variable and same exponent. It is not necessary that the coefficient is equal.

For example ab and 4ab are like terms because both the expression have the same variable a, b and exponent is also equal.

Looking into the given options, we can conclude that the expressions 2xy, -xy,1/2xy are like terms.

Hence, the like terms are

  • 2xy
  • -xy
  • 1/2xy

Part I: Marco rented a small moving van. The moving company charges $40 a day for up to 5 days. The input is the time, in days,
Snezhnost [94]

Given mapping is a function.

Domain: \{1,2,3,4,5\}

Range: \{40,80,120,160,200\}

Step-by-step explanation:

By observing Marco's mapping diagram we can see that every value in time is mapped to only one value in the cost. This means that there will be no repetition or same output to two different outputs so given mapping is a function.

<u>Domain:</u>

Domain is the set of all inputs of a function. Here time is input so domain of function is:

\{1,2,3,4,5\}

<u>Range:</u>

Range is the set of all outputs of the function on domain so the range of the given function is:

\{40,80,120,160,200\}

Hence,

Given mapping is a function.

Domain: \{1,2,3,4,5\}

Range: \{40,80,120,160,200\}

Keywords: Domain, range, function

Diego is solving this system of equations:
USPshnik [31]

The solutions of the equations are x = 1 and y = 2

The system of equations are

4x + 3y = 10

-4x + 5y = 6

Here we have to use the elimination method. Eliminate the x term and find the value of y term

Add both equation

3y + 5y = 10 +6

Add the like terms

8y = 16

y = 16 / 8

Divide  the terms

y = 2

Substitute the value of x in the first equation

4x + 3y = 10

4x + 3×2 =  10

Multiply the terms

4x + 6  = 10

4x = 10 - 6

4x = 4

x = 4 / 4

Divide the terms

x = 1

Hence, the solutions of the equations are x = 1 and y = 2

The table below shows two equations:
CaHeK987 [17]

Answer:

The solutions to equation 1 are x = 3, −1.5, and equation 2 has no solution.

Step-by-step explanation:

Rearranging the two equations, you get ...

  • |4x -3| = 9 . . . . . has two solutions
  • |2x +3| = -5 . . . . has no solutions (an absolute value cannot be negative)

The above-listed answer is the only one that matches these solution counts.

_____

Testing the above values of x reveals they are, indeed, solutions to Equation 1.
