Which represents a function?
Answer:
B
Step-by-step explanation:
For a function to be a function, every x value can only equal a single y value. A has two y values for one x value, and so does C and D. This leaves only B.
Pablo has 7 dogs. • Pablo feeds his dogs a total of 20 pounds of dog food each week. • Pablo feeds each dog an equal amount of dog food each time he feeds them. Which statement is true? Each dog is fed between 5 and 7 pounds of dog food each week. Each dog is fed between 5 and 7 pounds of dog food each week. Each dog is fed between 4 and 5 pounds of dog food each week. Each dog is fed between 4 and 5 pounds of dog food each week. Each dog is fed between 1 and 3 pounds of dog food each week. Each dog is fed between 1 and 3 pounds of dog food each week. Each dog is fed between 0 and 1 pound of dog food each week. Each dog is fed between 0 and 1 pound of dog food each week.
Answer: I believe its the one that says "each dog is fed between 1 and 3 pounds of dog food each week"
Step-by-step explanation:
To give each dog an equal amount you'd have to divide 20 by 7.
20 / 7
when you do that is doesn't come out to a whole number
20 / 7 = 2.8571428571
anything higher than 2.8 pounds would go over his limit of 20 pounds
so true statement I think would be the one that says between 1 and 3.

What is the equation of a circle with center -4, 7 and radius 6
Answer:
[tex]( x + 4 )^2 + ( y - 7 )^2 = 36[/tex]
Step-by-step explanation:
Use the circle equation, [tex]( x - h )^2 + ( y - k )^2 = r^2[/tex]
Plug in the center and radius:
[tex]( x + 4 )^2 + ( y - 7 )^2 = 6^2[/tex]
Simplify:
[tex]( x + 4 )^2 + ( y - 7 )^2 = 36[/tex]
So, the equation is [tex]( x + 4 )^2 + ( y - 7 )^2 = 36[/tex]

---> we get x = -14
---> we get x = 14
so, x = -12, or, x = 16

Angle ABC = 57°
Step-by-step explanation:
Hi there!
We're given:
⇒ ABD is a straight line
⇒ Angle ABC = 5x-18 degrees
⇒ Angle DBC = 8x+3 degrees
ABD is a straight line, meaning it measures an angle of 180 degrees.
Angles ABC and DBC create line ABD, so therefore, their sum is equal to 180 degrees:
[tex](5x-18)+(8x+3)=180[/tex]
Open the parentheses:
[tex]5x-18+8x+3=180[/tex]
Combine like terms:
[tex]13x-15=180\\13x=195[/tex]
Divide both sides by 13 to isolate x:
[tex]x=15[/tex]
Therefore, x = 15.
To find angle ABC, replace x with 15 in 5x-18:
[tex]5x-18\\=5(15)-18\\=75-18\\=57[/tex]
Therefore, the measure of angle ABC is 57 degrees.

What is the equation of the line that passes through the point (8,−3) and has an undefined slope?
Answer:
[tex]x = 8[/tex]
Step-by-step explanation:
Recall that horizontal lines have a slope of zero, while vertical lines have an undefined slope.
Therefore, the line must be vertical.
And since it is vertical, we will only need to consider the x-coordinate of our point.
The x-coordinate of (8, -3) is 8.
Hence, the equation of the line that passes through (8, -3) with an undefined slope is:
[tex]x = 8[/tex]
Answer: x= 8
Step-by-step explanation:
It is a vertical line that passes through point 8 on the x axis.

Hope it is helpful.....In the simplest form we can write the expression as - 12(w + 2).
We have the following expression -
9w - 3(- w - 8)
We have to write it in simplest form.
Expand the following expression -Δ = (x - α)(x - β)Expanding we get -
Δ = x(x - β) - α(x - β)
Δ = [tex]x^{2}[/tex] - βx - αx + αβ
According to the question, we have -
9w - 3(- w - 8)
Simplifying it, we get -
9w + 3(w + 8)
9w + 3w + 24
12w + 24
12(w + 2)
Hence, in the simplest form we can write the expression as - 12(w + 2).

Answer:
Question 22: x = 3Question 23: AB = 10Question 24: BD = 14Question 25: CE = 17Concept:
Here, we need to know the idea of the segment addition postulate.
The Segment Addition Postulate states that given 2 points A and C, a third point B lies on the line segment AC if and only if the distances between the points satisfy the equation AB + BC = AC.
If you are still confused, you may tell me or refer to the attachment below for a graphical explanation.
Solve:
Question 22. If AC = 16, what is x?
Given information
AC = 16
AB = x + 7
BC = 2x
Given expression deducted from the segment addition postulate
AB + BC = AC
Substitute values into the expression
x + 7 + 2x = 16
Combine like terms
x + 2x + 7 = 16
3x + 7 = 16
Subtract 7 on both sides
3x + 7 - 7 = 16 - 7
3x = 9
Divide 3 on both sides
3x / 3 = 9 / 3
[tex]\boxed {x=3}[/tex]
Question 23. What is AB?
Given information
x = 3
Given expression deducted from the segment addition postulate
AB = x + 7
Substitute values into the expression
AB = (3) + 7
[tex]\boxed {AB=10}[/tex]
Question 24. What is BD?
Given information
BC = 2x
CD = 3x - 1
x = 3
Given expression deducted from the segment addition postulate
BD = BC + CD
Substitute values into the expression
BD = 2x + 3x - 1
BD = 2(3) + 3(3) - 1
BD = 6 + 9 - 1
BD = 15 - 1
[tex]\boxed {BD=14}[/tex]
Question 25. What is CE?
Given information
CD = 3x - 1
DE = 2x + 3
x = 3
Given expression deducted from the segment addition postulate
CE = CD + DE
Substitute values into the expression
CE = 3x - 1 + 2x + 3
CE = 3(3) - 1 + 2(3) + 3
CE = 9 - 1 + 6 + 3
CE = 8 + 6 + 3
CE = 14 + 3
[tex]\boxed {CE=17}[/tex]
