<h3>Answer: Choice A.  {-2, -1, 0, 3, 5}</h3>

Explanation:

Every point of that given function is in the form (x,y). The x coordinate is always listed first. The domain is the set of allowed x values of a function. All we do is list the x coordinates of each point. Optionally you sort the x values from smallest to largest just to keep things consistent. Though a set like {1,2,3} is the same as {3,1,2}.

Side note: the range is the set of possible y values of a function

Answer:

A. {-2, -1, 0, 3, 5}

Step-by-step explanation:

The domain is the set containing the x-coordinates of all the points of the function.

{(<u>-2</u>, 1), (<u>0</u>, 0), (<u>3</u>, -1) (<u>-1</u>, 7), (<u>5</u>, 7)}

Domain: {-2, -1, 0, 3, 5}

Carl bought 19 apples of 2 different varieties to make a pie.The total cost of the apple was $5.10.Granny Smith apples cost $0.2
disa [49]

For this case we propose a system of equations:

x: Let the variable representing the quantity of Granny Smith apples

y: Let the variable representing the number of Gala apples

According to the statement we have:

x + y = 19\\0.25x + 0.30y = 5.10

From the first equation we have to:

x = 19-y

replacing in the second equation:

0.25 (19-y) + 0.30y = 5.10\\4.75-0.25y + 0.30y = 5.10\\4.75 + 0.05y = 5.10\\0.05y = 5.10-4.75\\0.05y = 0.35\\y = \frac {0.35} {0.05}\\y = 7

So, Carl bought 7 Gala apples

On the other hand:

x = 19-7 = 12

So, Carl bought 12 Granny Smith apples

Answer:

Carl bought 7 Gala apples and 12 Granny Smith apples

A family prepares an emergency kit for their home. The kit contains 63 gallons of drinking water. The​ family's daily drinking w
mr_godi [17]

Answer:

12 days

Step-by-step explanation:

Total gallons of the family's drinking water needs = gallons consumed by children + gallons consumed by adults

3\frac{1}{2} + 1\frac{3}{4} =

Converting to decimals

3.5 + 1.75 = 5.25 = 5\frac{1}{4}

If there are 63 gallons, the water supply would last for :

63 / 5.25 =12 days
