There are 300 dogs spread around 12 kennels across Texas. If x represents kennels and y represents the number of dogs, what is k, the constant of proportionality?
Answer:
k = 25
Step-by-step explanation:
If there are 300 dogs and 12 kennels, we divide 300 by 12, and get 25, which is the number of dogs per kennel.
Find the domain:
[tex]y=\frac{x+3}{|x-1|-4}[/tex]
Answer:
the function domain:
x<5 or x>5
Step-by-step explanation:
For this type of function, the domain is all real numbers. A function with a fraction with a variable in the denominator. To find the domain of this type of function, set the bottom equal to zero and exclude the x value you find when you solve the equation. A function with a variable inside a radical sign.

Determine the intercepts of the line.
Answer:
x: (5/2,0)
y: (0,5)
Step-by-step explanation:
To solve for x-intercept, substitute 0 for y.
-4x+7=2(0)-3
-4x+7=-3
-4x=-10
x=10/4 or 5/2
To solve for y-intercept, substitute 0 for x.
-4(0)+7=2y-3
7=2y-3
10=2y
y=5

What is the diagonal space of a cube? Can someone detail it to me with an example? Thanks
Answer:
four
Step-by-step explanation:
Space diagonals contrast with face diagonals, which connect vertices on the same face (but not on the same edge) as each other. For example, a pyramid has no space diagonals, while a cube (shown at right) or more generally a parallelepiped has four space diagonals.
Please answer question correct.
Answer:
A 13.75
Step-by-step explanation:
because you said the you 1 ponit for every right ans and -0.25 for incorret ans so 15 right ans would give you 15 ponits and 5 incorret ans would give you -1.25 so i add up
15+-1.25=13.75 or 55/4
i did do the math so it is right

Answer:
strong and negative
Step-by-step explanation:
because the slope of the line is negative, this would be a negative correlation. Also, since all the points are generally next to each other and there seems to be a trend since there are no outliers, this is strong

Distances in space are measured in light-years. The distance from Earth to a star is 4.1 × 1013 kilometers. What is the distance, in light-years, from Earth to the star (1 light-year = 9.46 × 1012 kilometers)? (5 points)
0.23 light-year
2.36 light-years
4.33 light-years
5.36 light-years
Answer:
5.36 light years
Step-by-step explanation:
if a light-year = 9.46 x 1012
9.46 x 1012 = 9512.8
4.1 x 1013 = 4153.3
After that you would subtract
9512.8 - 4152.3 = 5.360.5
the real answer is 5.36 light years
So the distance in light years from earth is 5.36 light years

A candle burns down at the rate of 0.5 inches per hour. The original height of the candle was 9 inches.
Part A: Write a list of 6 ordered pairs to show the height of the candle in inches (y) as a function of time in hours (x) from the first hour after it started burning. For example, the point (0, 9) would represent a height of 9 inches after 0 hours. Explain how you obtained the ordered pairs. (5 points)
Part B: Is this relation a function? Justify your answer using the list of ordered pairs you created in Part A. (2 points)
Part C: If the rate at which the candle burned was 0.45 inches per hour instead of 0.5 inches per hour, would the relation be a function? Explain your answer using input and output values. (3 points)
