Domain and Range both are real numbers for all odd-degree polynomial functions.
Writing in an Interval Form, note that we use the least value in the left and the most value in the right.
From [a,b], [a,b), (a,b] or (a,b) | a must be less than b.
Therefore, the D choice is wrong in Interval part (However, right in range and domain but just for interval order.)
So the answer is C.

Answer:
(0.5 -2.5)
Step-by-step explanation:
B is at (1, -5). A dilation by 0.5 means that these coordinates are multiplied by 0.5 each.
So 0.5(1) then 0.5(-5) = (0.5, -2.5)
You prepare 10 scoops of dog food for 5 dogs, and prepare 16 scoops of dog food for 8 dogs. What
is the constant of proportionality for the amount of dog food to the number of dogs? How many
scoops of dog food should you prepare for 6 dogs?
Answer:
12 scoops of dog food are needed for 6 dogs,
Step-by-step explanation:
Proportions
The number of scoops of dog foods and the number of dogs are proportional variables.
We are given that 10 scoops of dog foods are used for 5 dogs. This gives a proportion of 10/5=2 scoops per dog.
We also know that 16 scoops are used for 8 dogs. The proportion is also 16/8=2 scoops per dog.
Thus, the constant of proportionality is 2.
For 6 dogs, you need to prepare 2*6 = 12 scoops of dog food.
12 scoops of dog food are needed for 6 dogs,

Step-by-step explanation:
Vladas believes that an equation with a squared term is never a function of x. Which equation can be used to show Vladas that his hypothesis is incorrect?
x + y2 = 25
x2 – y = 25
x2 + y2 = 25
x2 – y2 = 25
Hence , the Vladas hypothesis which is incorrect is x² + y² = 25 which is option (c) .
Pythagoras theorem states that “In a trigon, the square of the flank facet is adequate to the total of squares of the opposite 2 sides“.The equation with a square term is rarely a perform of x declared by Vladas.
This is the statement relating to philosopher theorem that states that square of 2 range|number} is third number , these numbers once assigned to a triangle forms a right angulate triangle , the angle between 2 smaller sides is of 90°.
Among the four hypothesis given:
Option (C) : x²+ y²= 25 which is true.

what's the slope between (5,-2) and (-7,22)
Answer: The answer is: -2
Step-by-step explanation:
Here, suppose
(5,-2)=(x1, y1)
(-7,22)=(x2, y2)
Now, use the slope equation to find slope(m).
y2-y1=m(x2-x1)
or,m=y2-y1/x2-x1

Answer:
so it equation a= 0.2
Step-by-step explanation:
Answer:
The first one (a = 0.2 x 150). And a = 30
Step-by-step explanation:
To find a percentage of a number, you multiply it by 0.10 for 10%, 0.20 for 20%, and so on. Since a is the unknown number, that makes the first option correct. Now, we multiply .2 and 150 to get 30. That is the answer to the second part.

The scatter plot shows the number of people at a fair based on the outside temperature. How many fewer people would be predicted to be at the fair on a 100°F day than on a 75°F day? Fill in the blanks:
The slope is __.
For each degree that the outside temperature increases, the fair attendance decreases by __ thousand people.
The difference between 75°F and 100°F is __°F.
-0.16 *__ =__
About __ thousand fewer people are predicted
to be at the fair on a 100°F day than on a 75°F day.
Using the regression scatterplot given, the slope of the relationship between the number of people and temperature and the questions can be answered thus :
Slope = Δy / ΔxSlope = (12-4) / (60 - 110) = 8/50 = 0.16
Hence, the slope = 0.16
2.)
Using the slope value, which is the rate of change,
For each degree increase in outside temperature, fair attendance decreases by 0.16 thousand people.
3.)
The difference between 75°F and 100°F is (100 - 75) = 25°F
Multiplying the slope by the difference :
-0.16 × 25 = 4
Hence, about 4000 fewer people are predicted to be at the fair on a 100°F day than on a 75°F day.

pieces of cornbread. Every order
receives 2 piece of cornbread. At the
end of their lunch rush, there are 28
pieces of cornbread left. How many
orders did the restaurant take?
Answer:
46 orders.
Step-by-step explanation:
(10*12) - 2x = 28
120 - 2x = 28
-2x = 28 - 120
-2x = -92
x = -92/2
x = 46

Step-by-step explanation:
At a store, a hat has a regular price of x dollars. During a sale, the price of the hat is discounted by 20%. The expression 0.8x describes the discounted price, in dollars, of the hat. Which expression also describes the discounted price, in dollars, of the hat?
Answer: D) x - 0.2x
Step-by-step explanation:
The hat has a regular price of x dollars.
This price is reduced by 20% so the relevant expression for the discount is; 20% * x or; 0.2x
The discounted price will be the price of the hat less the discount which means the formula will be;
= Price - discount
= x - 0.2x
