Mary is babysitting a 4-year-old. The little boy wants to play in the kiddie pool in the backyard. Mary knows that using the hose that is near the kiddie pool will take 30 minutes to fill up. The little boy has already asked 17 times if the pool is ready but she hasn't even turned on the water yet. Mary also knows that the hose from the front yard works faster and can fill the pool in 1/2 the time as the hose in the back yard. If she can use both hoses at the same time, how long will it take for the pool to fill up?

x-2.5y=12.5
-x+2.3y=11.9

Answers

Answer: the answers are x = -292.5 and y = -122

Step-by-step explanation:

Elimination is combining equations to obtain an equation with just one variable. This is only possible if the coefficients of one variable in both equations are opposed and will cancel each other out when put together. Elimination is most effective when it occurs naturally in the equations, but equations may also be modified to produce typical coefficients by multiplying or dividing equations by a given value. The next step would be to utilize the equation we devised to determine the variable's worth and then insert that value back into the original equation to determine the remaining variable.

For solving the question to find x we have to make the coefficients of y the same. for that, we will multiply the first equation by 2.3 and the second equation by 2.5.

After that, we get the 2 equations as

2.3x-5.75y = 28.75

-2.5x+5.75y = 29.75

then by adding the 2 equations we get

-0.2x = 58.5

and by dividing 58.5 by -0.2 we get

x = -292.5

substituting the value of x in any equations above we get

y = -122

The table shows a proportional relationship between the number of pounds of grapes

A row of values is missing in the table.
Which number of pounds of grapes and total cost of the grapes could be used as the
missing values in the table?
Select each correct response.
Question 1 options:

Pounds of grapes: 2
Total cost: $1.38

Pounds of grapes: 3
Total cost: $2.53

Pounds of grapes: 6
Total cost: $3.68

Pounds of grapes: 8
Total cost: $5.52

Pounds of grapes: 11
Total cost: $8.97

Answers

Answer:

Pounds of grapes: 11

Total cost: $8.97

Step-by-step explanation:

Because when you look at the prices, the last answer (Pounds of grapes: 11

Total cost: $8.97)is the most correct because it is adding by 2 (2, 4, 6, 8) every time. Its not exactly 8 but its the closet number :)

Which statements are true? Select all that apply.
The graph of the function will not form a straight line, so it is nonlinear.
The function is not proportional.
The function goes through the origin.
The difference between consecutive output values is a constant.

Answers

Answer:

1st 2nd and 3rd box

Step-by-step explanation:

1. It does not form a straight line because the output is not proportional. (it does not follow a pattern)

2. the line is not proportional because it does not follow a pattern or ratio of any kind (2468 is proportional because it follows the pattern of 2)

3. the origin is the coordinates (0,0) and the table has that labeled in the diagram therefore the graph does go through the origin

4. the output is not constant (output is 0149) because it does not show any sort of pattern. therefore the 4th box is incorrect.
