Answer:
Graph D (last graph)
Step-by-step explanation:
y + 2 > 5
first subtract 2 from both sides
y > 3
Now that we know the solution to y we can plot it. We know it must start at 3, but also not be included because our solution is not ≥. This means we have an open box at 3 and an arrow in the positive direction.

The equation 4 ∙ 5 = 5 ∙ 4 demonstrates the ________property of multiplication.
Answers
Answer:
The equation 4 ∙ 5 = 5 ∙ 4 demonstrates the Commutative property of multiplication.
Step-by-step explanation:
Commutative property is A × B = B × A
So the equation 4 ∙ 5 = 5 ∙ 4 is same as commutative property
Answer:
The equation 4 ∙ 5 = 5 ∙ 4 demonstrates the commutative property of multiplication.
Step-by-step explanation:
The commutative property means that the positions of the numbers on each side of the equation can be swapped and both sides would be equal.
You can think of it as A x B = B x A

what is representation of root?The principal nth root of a is written as n√a , where n is a positive integer greater than or equal to 2. In the radical expression, n is called the index of the radical.
A radical symbol √ is used to represent a square root; the number or expression included within the radical symbol, designated by the letter a below, is known as the radicand.
We have that [tex]77 ^ {1/10}[/tex].
Now, if we have given that √4 we can write it as [tex]\sqrt[2]{4}[/tex]
Again, if we have [tex]7^{1/3}[/tex] we can write it as [tex]\sqrt[3]{7}[/tex]

–5(1 – 5x) + 5(–8x - 2) = -4x – 8x
Answers
Answer: x = -5
-------------------------------------------------------------------------------------------------------------
Step-by-step explanation:
Let's solve your equation step-by-step.
−5(1−5x)+5(−8x−2)=−4x−8x
-------------------------------------------------------------------------------------------------------------
Step 1: Simplify both sides of the equation.
−5(1−5x)+5(−8x−2)=−4x−8x
(−5)(1)+(−5)(−5x)+(5)(−8x)+(5)(−2)=−4x+−8x(Distribute)
−5+25x+−40x+−10=−4x+−8x
(25x+−40x)+(−5+−10)=(−4x+−8x)(Combine Like Terms)
−15x+−15=−12x
−15x−15=−12x
-------------------------------------------------------------------------------------------------------------
Step 2: Add 12x to both sides.
−15x−15+12x=−12x+12x
−3x−15=0
-------------------------------------------------------------------------------------------------------------
Step 3: Add 15 to both sides.
−3x−15+15=0+15
−3x=15
-------------------------------------------------------------------------------------------------------------
Step 4: Divide both sides by -3.
−3x /−3 = 15/ −3
x=−5

Suppose you need to put a fence around a rectangular garden that has a perimeter of 64ft. The width is 12ft less than the length. Find the width and length of the garden.
Answers
Answer:
x=length

you techinally have to count 2 lengths and 2 widths.
2x + 2x - 24= 64
4x = 88
x = 22
so the length is 22 and the width is 10

what is 6xy . 12 over x 100 over 6
Answers
X2 + -6xy + -12 = 0
Reorder the terms:
-12 + X2 + -6xy = 0
Solving
-12 + X2 + -6xy = 0
Solving for variable 'X'.
Move all terms containing X to the left, all other terms to the right.
Add '12' to each side of the equation.
-12 + X2 + 12 + -6xy = 0 + 12
Reorder the terms:
-12 + 12 + X2 + -6xy = 0 + 12
Combine like terms: -12 + 12 = 0
0 + X2 + -6xy = 0 + 12
X2 + -6xy = 0 + 12
Combine like terms: 0 + 12 = 12
X2 + -6xy = 12
Add '6xy' to each side of the equation.
X2 + -6xy + 6xy = 12 + 6xy
Combine like terms: -6xy + 6xy = 0
X2 + 0 = 12 + 6xy
X2 = 12 + 6xy
Simplifying
X2 = 12 + 6xy
Reorder the terms:
-12 + X2 + -6xy = 12 + 6xy + -12 + -6xy
Reorder the terms:
-12 + X2 + -6xy = 12 + -12 + 6xy + -6xy
Combine like terms: 12 + -12 = 0
-12 + X2 + -6xy = 0 + 6xy + -6xy
-12 + X2 + -6xy = 6xy + -6xy
Combine like terms: 6xy + -6xy = 0
-12 + X2 + -6xy = 0
The solution to this equation could not be determined.
