2 examples of a commutative property?
Answer:
hope this helps :)
Step-by-step explanation:
Commutative property of addition: Changing the order of addends does not change the sum. For example, 4 + 2 = 2 + 4 4 + 2 = 2 + 4 4+2=2+44, plus, 2, equals, 2, plus, 4.

If the base angles of a triangle are congruent, use the Law of Sines to show the triangle is isosceles.
Answer:
The Isosceles Triangle Theorem States that if a triangle contains 2 congruent sides, then the angles opposite those sides are congruent. This theorem can be proved using the Law of Sines: The Law of Sines states that: asinA=bsinB=csinC If a=c, making △ABC an isosceles triangle, then asinA=asinC!
The law of sins says: a/SinA = b/SinB = c/sinC
For this to be an isosceles triangle then side a must equal side c
so then a/sinA = c/sinC
Then you can divide both sides by a and raise to the power of -1 and you would get angle A = angle C which makes this isosceles.
Find the HCF of terms and factorise: 20x3 – 40x2 + 80x
Answer:
The largest factor that can be pulled out of that expression is 20x, giving you 20x(x² - 2x + 4)
Step-by-step explanation:
20x³ - 40x² + 80x
= 20x(x² - 2x + 4)

Carter bought 3/4 yard of fabric for an art project. He used 3/8 yard of the fabric. What fraction of a yard of fabric does Carter have left?
Answer:
3/8
Step-by-step explanation:
He purchased 3/4 yard of fabric, then used 3/8 of it. You would need to subtract the 3/8 from 3/4 because the fabric is being used up.

When solving this system by elimination, which variable is the most convenient to eliminate,
x or y?
2x + y = 7
3/2 x - y = 7/2
Answer:
Y is the appropriate variable and the most easiest and convenient to eliminate
name 2x + y = 7 as equation i
and 3/2 x - y = 7/2 as equation ii
then add equation i and ii together
(3/2 + 2) x + y - y = (7 + 7/2)
(7/2) x = (21/2)
x = 3
then put in x = 3 in equation i
4 + y = 7
x = 7 - 4
x = 3
Therefore x = 3 and y = 3

Mega Movies hosted a film premiere on Friday night. They charged $7 for adults and $4 for
children. Ninety-four adults and children attended, and $592 was made in ticket sales. How
many children and how many adults went to the film premiere?
Answer:
72 adults
22 children
Step-by-step explanation:
Let c = no. of children
a = no. of adults
Then 4c = total sales for the children and
7a = total sales for the adults
So, a + c = 94 and 7a + 4c = 592
-4a - 4c = -376
3a = 216
a = 72 adults
72 + c = 94
c = 22 children

Write an equation in point-slope form for the line through the given point with the given slope. (3,−4);m=−14
Answer:
y=-14x-4
Step-by-step explanation:
Answer:
y + 4 = - 14(x - 3)
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b ) a point on the line
Here m = - 14 and (a, b ) = (3, - 4 ) , then
y - (- 4) = - 14(x - 3) , that is
y + 4 = - 14(x - 3)

Which expression best estimates 6 3/4 ÷ 1 2/3
7 ÷ 2
6 ÷ 1
8 ÷ 3
3 ÷ 2
Answer:
7 divided by 2
Step-by-step explanation:
I say 7 divided by 2 because if you round 6 3/4 up one you will get 7 and if you round 1 2/3 up one you get 2 so 7 divided by 2 makes most sense
If f(x)=x+5, what is f-'(x)?
Step-by-step explanation:
Given
f(x) = x + 5
Let
y = f(x)
y = x + 5
Interchanging the roles of x and y we get
x = y + 5
y = x - 5
f^-1 (x) = x - 5

Use words and symbols to describe the value of each term as a function of its position. Then find the value of the twelfth term in the sequence.
Answer:
21 for the first one, 144 for the second
Step-by-step explanation:
If you're seeing the same problem I am in class, the rule is: N + 9
N is equal to 12 in this equation
12 + 9 is 21.
So, the answer is 21
If there is a second problem, like there is for the one I'm seeing, then this is the answer for that-
Is 12(12)= 144
Hope this helps!

Answer:
12
Step-by-step explanation:
12×12=144
12 squared equals 144 so square root is 12.
9514 1404 393
Answer:
12
Step-by-step explanation:
The prime factorization of 144 is ...
144 = 9·16 = 2·2·2·2·3·3
Grouping pairs of similar factors, we have ...
144 = (2·2)·(2·2)·(3·3) = (2·2·3)·(2·2·3) = 12·12
√144 = √(12²) = 12
Expand and simplify (x+3)(x-4)
Answer:
Step-by-step explanation:
Use FOIL method.

= x² - 4x + 3x - 12
= x² - x - 12

write a short explanation of why the distance formula works and include a discussion of why either point can be point 1 or point 2
Answer:
Finding the distance between two distinct points on a plane is the same as finding the hypotenuse of a right triangle. From this perspective, the distance formula states that the distance of two distinct points on a plane is equal to the square root of the sum of the square of the rise and run.
I can not Put Out The Points So Im sorry.
