prove that if a is a factor of b and b is a factor of c, then a is a factor of c
Answer:
The set of numbers a = 3, b = 6, and c = 9 proves the hypothesis because 3 is a factor of 6 and 3 is a factor of 9. Property 1 states that therefore 3 is a factor of 9 + 3 =12, which we know is true because 3 × 4=12. You can prove that this property is true for all integers if you know what the term factor means.

What is the measure of
Answer:
64.4
Step-by-step explanation:
In one of the trig formulas, it states sin <a/A = sin<b/B = sin<c/C
So we have in this case:
sin(70)/12 = sin x/14 Note: x is just a variable for the angle <ABC
14(sin70)/12 = sin x
sin^-1(14(sin70)/12) = x
x=64.4

Answer:
x = 100°
Explanation:
The polygon has 6 sides, meaning it's a hexagon. In the picture you can see the following steps under #1:
(6-2) x 180° = 4 x 180 = 720°
720 is the total amount that all the angles should add up to, including the missing number x.
To solve for x add all of the angles up:
120 + 156 + 145 + (x + 9) + x + 90 = 720
520 + 2x = 720 (subtract 520 from both sides)
-520
2x = 200 (divide 200 by 2 to have x on its own)
x = 100°
To make sure it's correct, plug in the value (100°) for x in the original equation to check the answer:
120 + 156 + 145 + 100 + 9 + 100 + 90 = 720
720 = 720 Correct

You and four friends go to a baseball game. The total
cost is $110. How much did each ticket cost? One step word problem HELP ME PLEASEEE
Step-by-step explanation:
You and four friends = 5 people
To see how much one ticket costs we have to divide the total amount spent by the number of people who bought tickets.
Total amount spent: $110
People who bought tickets:5
110÷5=22
Each ticket cost $22
Answer:
$110÷5
=$22
therefore each ticket costs $22
Are all polyhedrons solids?
Answer:
A polyhedron is a 3-dimensional solid made by joining together polygons. The word 'polyhedron' comes from two Greek words, poly meaning many, and hedron referring to surface. The polyhedrons are defined by the number of faces it has.

Solve the following proportion. Round your answer to two decimal places.
Answer:
x = 2
Step-by-step explanation:
[tex]\frac{x+1}{x+3}[/tex] = [tex]\frac{3}{5}[/tex] ( cross- multiply )
5(x + 1) = 3(x + 3) ← distribute parenthesis on both sides
5x + 5 = 3x + 9 ( subtract 3x from both sides )
2x + 5 = 9 ( subtract 5 from both sides )
2x = 4 ( divide both sides by 2 )
x = 2
Identify the domain of the function shown in the graph.
y
10
10
10
-10
A. X20
B. All positive real numbers
C. All real numbers
D. All positive integers
The domain of the function shown in the graph are all real numbers. Therefore, option C is the correct answer.
What is domain and range of the function?The domain and range are defined for a relation and they are the sets of all the x-coordinates and all the y-coordinates of ordered pairs respectively.
The coordinate points from the given graph are (-2, 0) and (10, 6).
Here, slope m=(6-0)/(10+2)
= 6/12
= 1/2
= 0.5
Substitute m=0.5 and (x, y)=(-2, 0) in y=mx+c, we get
0=0.5(-2)+c
0=-1+c
c=1
So, equation of a line is y=0.5x+1
Find the domain by finding where the equation is defined. The range is the set of values that correspond with the domain.
Domain: (−∞,∞),{x|x∈R}
Range: (−∞,∞),{y|y∈R}
Therefore, option C is the correct answer.

Answer:
[tex]\displaystyle [0, 8][/tex]
Explanation:
This is an automatic give-away. If you look clocer, you will see that both equations have identical b-values of 8, telling you that both equations have identical y-intercepts. So, by definition, x is zero, which means you are left with the b-value of eight, giving you the solution to the system.

Find a polynomial F(x ) of degree 5 that has the following zeros.
8(multiplicity 2) -2, -9, 0
Leave your answer in factored form.
F(x) = ?
Answer:
f(x) = x(x + 2)(x + 9)(x - 8)²
Step-by-step explanation:
Given x = h is a zero of f(x) then (x - h) is a factor
If h has multiplicity 2 then the factor is squared , that is (x - h)²
here the zeros are x = 8 of multiplicity 2 , x = - 2, x = - 9, x = 0
then (x - 8)² , (x - (- 2)) , (x - (- 9)) , x - 0 are the factors, that is
(x - 8)² , (x + 2) , (x + 9) and x
f(x) = x(x + 2)(x + 9)(x - 8)² ← in factored form

A 6-kilogram bag of cement costs $24.81. What is the unit price, rounded to the nearest cent?
Answer:
$4.14
Step-by-step explanation:
To find the unit price, we divide $24.81 by 6.
24.81/6 = 4.135
The question says to round to the nearest cent so we round it to 4.14.
4.135 = 4.14

Megan will multiply the first equation by 3 then add the result to the second equation.
What will be the resulting system of equations that produces the same solutions?
The resulting equation will be x + y = 4 and 4y =20
System of equationGIven the system of equation given as:
x + y = 4
-3x + y = 8
If Megan multiplies the first equation by 3 then add the result to the second equation, the resulting equation will be:
3x + 3y = 12
-3x + y = 8
