State which of the following sets of ordered pairs represent a function.

1 answer:

8 0

A function is an equation that has only one answer for y for every x. This means that:

Set A and Set C are functions because their y values don’t repeat.

Set B is NOT a function because the 2 in the y values repeats twice.

Hope I helped!

Answer: $4.69

Step-by-step explanation:

Make equivalent fractions for each fruit.

Apples: 1.62/1 = x/2.5

X = $4.05 for 2.5 pounds of apples

Bananas: 0.48/1 = x/1.3333333333

X = .64 for 1.3333333333 pounds of bananas

Now add the results together to find the total cost.

4.05 + .64 = $4.69

The cafeteria sold 41 corn chips and 80 potato chips.

Step-by-step explanation:

Let,

Corn chips = x

Potato chips = y

Price of corn chips = $0.80

Price of potato chips = $0.60

According to given statement;

x+y= 121 Eqn 1

0.80x+0.60y=80.80 Eqn 2

Multiplying Eqn 1 by 0.80

$0.80(x+y= 121)\\0.80x+0.80y=96.80\ \ \ Eqn\ 3$

Subtracting Eqn 2 from Eqn 3

$(0.80x+0.80y)-(0.80x+0.60y)=96.80-80.80\\0.80x+0.80y-0.80x-0.60y=16\\0.20y=16$

Dividing both sides by 0.20

$\frac{0.20y}{0.20}=\frac{16}{0.20}\\y=80$

Putting y=80 in Eqn 1

$x+80=121\\x=121-80\\x=41$

The cafeteria sold 41 corn chips and 80 potato chips.

Cierra is buying juice. She needs 5 liters. A half liter juice cost $2.86. A 250-milliliter container of juice costs $1.05. Wh

xenn [34]

Answer: 250 mL Juice container

Step-by-step explanation:

Given

Half liter juice costs $2.86 i.e.

$\dfrac{1}{2}\ L\rightarrow\$2.86\\\\1\ L\rightarrow\dfrac{2.86}{\frac{1}{2}}=\$5.72\\\\5\ L\rightarrow\$28.6$

A 250 mL juice costs $1.05 i.e.

$250\ mL=0.25\ L\rightarrow \$1.05\\\\1\ L\rightarrow \dfrac{1.05}{0.25}=\$4.2\\\\\Rightarrow 5\ L\rightarrow \$21$

The cost of 250 mL Juice packet is low for 5 L quantity, therefore, Cierra must buy 250 mL Juice container
