Answer: The Commutative Property of Multiplication
Step-by-step explanation: The commutative property of multiplication states that when two numbers are being multiplied, their order can be changed without affecting the product. In this case, changing the order of 16 and 2, doesn’t matter because they will always be equivalent to each other.
Plzzzz help ASAP. What is an equation of the line that passes through the point (1,6) and is perpendicular to the line x+3y=27
Answer:
y = 3x + 3
Step-by-step explanation:
x + 3y = 27
3y = -x + 27
y = [tex]\frac{-1}{3}x +\frac{27}{3}[/tex]
y = [tex]\frac{-1}{3}x + 9[/tex]
m₁ = -1/3
the slope of the line perpendicular to x + 3y = 27 is m₂ = -1/m₁
m₂ = [tex]-1 * \frac{-3}{1}[/tex] = 3 , Point (1 , 6)
y - y1 = m (x -x1)
y -6 = 3(x - 1)
y - 6= 3x - 3
y = 3x - 3 +6
y = 3x + 3
Answer:
3x-y=27
Step-by-step explanation:
perpendicular is making a 90 degree angle, so it would need to be a slope of 3 if the other is -1/3.
y=9, x=27
3x-y=27 is the polar opposite, and should work, sorry if wrong. hard to do in my head without a graph to help.

In the diagram triangle XYZ is congruent or equal to triangle MNL. Copy and complete the statement.
Answer:
5. 124 degrees
6. 23
7. 8
8. LN with a line over the top
9. Triangle symbol ZYX
10.Triangle symbol NML
Step-by-step explanation:
5. You are working with congruences. Therefore, for #5 it is asking about the angle Y. Look at the diagrams. Angle Y is congruent with angle N therefore your answer is 124 degrees.
6. In 6 they want to know what angle M is. Well, you already know that the interior of a triangle is 180 therefore, you would subtract 180-124=56. You then subtract angle L which is the same as angle X and therefore is 33. 56-33=23. So angle M is 23.
7. For 7 they want to know what the line YX is. Again, we are working with congruences and therefore line YX is the same as line NM so the answer is
8. In 8, the want to know what the line YZ is equal to. Working with congruences, you know that line YZ=LN. Make sure you put the line over LN as they did with YZ.
9.Working with congruencies, they want to know what triangle LNM is equal to. Looking at the diagram, you know that since they are congruent, triangle LNM is equal to triangle ZYX. Make sure you use the triangle symbol.
10. Again, they what to know what the triangle is equal to. Look at your diagram. Line YX is equal to line NM. Line XZ is equal to line ML. Line ZY is equal to line LN. to triangle YXZ is equal to triangle NML. I think they just want you to put the letters in the corresponding order.
I hope these are correct and that this helps you.
Write an integer for situation
5 degrees below 0
Answer:
-5 degrees
hope this helps
Answer:
-5
Step-by-step explanation:
An integer is a positive or negative number that has no fractions or decimals.
5 degrees above zero is 5 degrees because 0 + 5 = 5
5 degrees below zero is -5 degrees because 0 - 5 = -5

The first number is 7 greater than a second number. Twice the first number is 4 more than three times the second. Find the two numbers.
Step-by-step explanation and answer:
Setting up a system of equations would be the easiest method for this question. The first number will be x. The second number will be y. According to the question:
x+1=y
2x-4=5y
Since the first equation is already solved for y, you can plug the whole first equation in for y in the second equation, then solve for x.
2x-4=5(x+1) Distribute the 5
2x-4=5x+5 Subtract 5x from 2x
-3x-4=5 Subtract -4 from 5 (add 4 to 5)
-3x=9 Divide to get the x by itself
-3=x
Now that you have x solved for, you can plug it into the first equation (or second, if you prefer) to solve for y.
x+1=y
-3+1=y
-2=y

An astronomer knows that a satellite orbits the Earth in a period that is an exact multiple of 1 hour that is less than 1 day. If the astronomer notes that the satellite completes 11 orbits in an interval that starts when a 24-hour clock reads 0 hours and ends the clock reads 17 hours, how long is the orbital period of the satellite?
Answer: The Satellites Orbits the Earth every 19 hours!
Step-by-step explanation:
Okay, I went to go re-searching for this question hopefully this helps love, from below! You should write this down, so it's easier for you to remember.
The total orbital period of the satellite is 1.54 hours and this can be determined by using the given data.
Given :
An astronomer knows that a satellite orbits the Earth in a period that is an exact multiple of 1 hour that is less than 1 day.The astronomer notes that the satellite completes 11 orbits in an interval that starts when a 24-hour clock reads 0 hours and ends the clock reads 17 hours.The following steps can be used in order to determine the total orbital period of the satellite:
Step 1 - Let the number of hours to complete one orbit be 'x'.
Step 2 - According to the given data, the astronomer notes that the satellite completes 11 orbits in an interval that starts when a 24-hour clock reads 0 hours and ends the clock reads 17 hours.
Step 3 - So, the linear equation that represents the given situation is:
11x = 17
x = 17/11
x = 1.54 hours

If 4(r+2)-13=11, what is the value of r ?
Answer:
r=4
Step-by-step explanation:
First you multiply 4 by r which gives you 4r. Then you multiply 4 by 2 to give you 8.So it looks like this now
4r+8-13=11
Now you add thirteen to both sides and get
4r+8= 24
Then you subtract both sides by 8 to get 16
4r=16
Then you divide both sides by 4 to get 4
r=4
The value of r for equation 4(r+2)-13=11 is 4.
What is an equation?An equation is a combination of different variables, in which two mathematical expressions are equal to each other.
The given equation is,
4(r+2)-13=11,
Add 13 in both the sides,
4(r+2)-13+13=11+13,
4(r+2) + 0 = 24
4(r+2) = 24
Divide by 4 both sides,
r+2 = 6
r= 4
The value of r is 4.
