Answer:

This is a function.

Step-by-step explanation:

To be a function every x must have only one y as its partner. In this format (two ovals with numbers in them and arrows showing the pairs) If EVERY x has only ONE arrow pointing away from it, then it is a function. If any x has MORE THAN ONE arrow pointing away from it, at two different y-numbers, then it is NOT a function.

At the football game, 4 hamburgers and 6 soft drinks cost $34, and 4 hamburgers and 3 soft drinks cost $25. Which two equations
olga_2 [115]

Answer:

 4x+6y=34\\\\4x+3y=25

Step-by-step explanation:

Let be "x" the cost in dollars of a hamburger and "y" the cost in dollars of a soft drink.

The cost of 4 hamburguers can be represented with this expression:

4x

And the cost of 6 soft drinks  can be represented with this expression:

6y

Since the total cost for 4 hamburgers and 6 soft drinks is $34, you can write the following equation:

4x+6y=34   <em>[Equation 1]</em>

 The following expression represents the the cost of 3 soft drinks:

3y

According to the information given in the exercise, the total cost for 4 hamburgers and 3 soft drinks is $25. Then, the equation that represents this is:

4x+3y=25 <em> [Equation 2]</em>

Therefore, the <em>Equation 1 </em>and the <em>Equation 2 </em>can be used to determine the price of a hamburger and the price of a soft drink

A fruit company delivers its fruit in two types of boxes: large and small. A delivery of 5 large boxes and 3 small boxes has a t
faltersainse [42]

Answer:

one large box equals 15.75<em>kg</em>

one small box equals 13.75<em>kg</em>

Step-by-step explanation:

First, identify your variables:

Let "l" represent the weight of one large box.

Let"s" represent the weight of one small box.

Then, stack the two equations on top of each other:

5l+3s=120\\7l+9s=234

Next, multiply the first equation by 3 so we can use elimination of the "s" variable to find the "l" variable first:

3(5l+3s=120)\\7l+9s=234\\\\15l+9s=360\\7l+9s=234

Now, subtract the two equations to cancel out the s-variable and find the l-variable:

15l+9s=360\\-(7l+9s=234)\\8l=126\\\frac{8l}{8}=\frac{126}{8}\\l=15.75

Then, substitute your l-variable in the original first equation to find the s-variable:

5l+3s=120\\5(15.75)+3s=120\\78.75+3s=120\\78.85-78.75+3s=120-78.75\\3s=41.25\\\frac{3s}{3}=\frac{41.25}{3}\\s=13.75

With all the information that is collected, you find that one large box weighs 15.75<em>kg</em> and one small box weighs 13.75<em>kg</em>.
