how do I find the absolute value of |2y-9|=1
Answer:
y=4,5
Step-by-step explanation:
Anything inside an absolute value will become postive.
So, 2y-9 can be -1 because the absolute value of -1 is 1.
Knowing this,
2y-9 = 1
or
2y-9 = -1
2y-9=1
2y=10
y=5
and
2y-9=-1
2y=8
y=4
y=4,5

Gianni used 6 gb out of 8 gb includes in his cell phone plan. What percent of his data did he use
Answer:
75%
Step-by-step explanation:
If he used 6 out of 8 gb of his cell phone plan we can write that as a fraction as 6/8.
We can simplify 6/8 to 3/4. And 3/4 when divided is equal to 0.75 which when written as a fraction is 75%.

What is the answer to -12 = 4(f-6)
Answer:
Step-by-step explanation:
-12 = 4(-6 + f)
-12 = (-6 * 4 + f * 4)
-12 = (-24 + 4f)
-12 = -24 + 4f
Solving for variable 'f'.
Move all terms containing f to the left, all other terms to the right.
Add '-4f' to each side of the equation.
-12 + -4f = -24 + 4f + -4f
Combine like terms: 4f + -4f = 0
-12 + -4f = -24 + 0
-12 + -4f = -24
Add '12' to each side of the equation.
-12 + 12 + -4f = -24 + 12
Combine like terms: -12 + 12 = 0
0 + -4f = -24 + 12
-4f = -24 + 12
Combine like terms: -24 + 12 = -12
-4f = -12
Divide each side by '-4'.
f = 3
Simplifying
f = 3

Release your mouse button when the item is place. If you change your mind, drag the item to the trashcan. Click the trashcan to clear all your answers. Indicate, in standard form, the equation or inequality that is shown by the graph.
The equation that is shown by the graph is y = -x + 4
How to determine the equation or inequality that is shown by the graph?From the graph, we have the following observation:
The line of the graph is a straight lineNo parts of the graph are shadedThe above means that the graph represents a linear equation
The points on the graph are
(0, 4) and (4, 0)
Calculate the slope using
m = (y2 - y1)/(x2 - x1)
This gives
m = (0 - 4)/(4 - 0)
Evaluate
m = -1
The linear equation is represented as
y = mx + c
So, we have
y = -x + c
Where c = y, when x = 0
So, we have:
c = 4
This means that
y = -x + 4
Hence, the equation that is shown by the graph is y = -x + 4

Given that line CD is a perpendicular bisector of triangle ABC, if side AB has a length of 6 and side AC has a length of 12 what is the length of side CD? Write your answer to the
nearest hundredth ie 179.50.
Using the Pythagorean Theorem, the length of CD, to the nearest hundredth, is: 11.62.
How to Apply the Pythagorean Theorem?The measure of the longest side of a right triangle when squared will be equal to the sum of the squares of the other smaller sides of the right triangle.
Given the following:
Side AB = 6
Side AC = 12
Based on the perpendicular bisector theorem, AD = 1/2(AB) = 1/2(6) = 3.
Using the Pythagorean theorem, we have:
Length of CD = √(AC² - AD²)
Length of CD = √(12² - 3²)
Length of CD = √(144 - 9)
Length of CD = 11.62
Thus, using the Pythagorean Theorem, the length of CD, to the nearest hundredth, is: 11.62.

If you add two to twice a number, the result is twelve. What is the number?
The unknown number will be 5 if we add two to twice a number, the result is twelve.
Let the unknown number be x.
Then the twice of the known number be 2x.
According to the given question.
If we add two to twice a unknown number, the result is twelve.
So, from the given scenario we can say that
2 + 2x = 12
Now we have a linear equation in one variable 2 + 2x = 12 and we have to solve it for x which gives us the unknown number.
Therefore,
2 + 2x = 12
⇒ 2x = 12 - 2 (subtracting 2 from both the sides)
⇒ 2x = 10
⇒ x = 10/2
⇒ x = 5
Hence, the unknown number will be 5 if we add two to twice a number, the result is twelve.

Name the property of real numbers illustrated by the equation (2 + x) + 3 = 2 + (x + 3).
Identity Property
Distributive Property
Associative Property
Commutative Property
Answer:
This equation illustrates the associative property of the real number field, [tex](\mathbb{R},\, +,\, \cdot)[/tex].
Step-by-step explanation:
All four choices here are indeed properties of the field of real numbers, [tex](\mathbb{R},\, +,\, \cdot)[/tex]. However, the equation [tex](2 + x) + 3 = 2 + (x + 3)[/tex] makes use of only the associative property.
Identity PropertyBy identity property of fields, the real number field [tex](\mathbb{R},\, +,\, \cdot)[/tex] should contain an identity element [tex]e \in \mathbb{R}[/tex], such that for any element of that field [tex]a \in \mathbb{R}[/tex]:
[tex]a + e = a[/tex].
In particular, the identity element of the real number field [tex](\mathbb{R},\, +,\, \cdot)[/tex] is the real number [tex]0[/tex]. The identity property (of addition) would then read:
[tex]a + 0 = a[/tex] for any [tex]a \in \mathbb{R}[/tex].
Distributive PropertyBy the distributive property of fields, for any three elements ([tex]a,\, b,\, c \in \mathbb{R}[/tex]) of the real number field [tex](\mathbb{R},\, +,\, \cdot)[/tex]:
[tex]a\cdot (b + c) = a \cdot b + a \cdot c[/tex].
[tex](a + b) \cdot c = a \cdot c + b \cdot c[/tex].
Note that this property features both addition and multiplication in the same equation. However, the equation in the question includes only addition. Therefore, this property would not apply here.
Associative PropertyBy the associative property of fields, for any three elements ([tex]a,\, b,\, c \in \mathbb{R}[/tex]) of the real number field [tex](\mathbb{R},\, +,\, \cdot)[/tex]:
[tex]a + (b + c) = (a + b) + c[/tex].
[tex]a \cdot (b \cdot c) = (a \cdot b) \cdot c[/tex].
In particular, the equation [tex](2+ x) + 3 = 2 + (x + 3)[/tex] (where [tex]x \in \mathbb{R}[/tex]) illustrates the associative property of addition of the real number field.
Note that even though the location of the parentheses have changed, the elements are still in the same place (with [tex]a[/tex], [tex]b[/tex], and [tex]c[/tex] in the same order on both sides of the two equations.)
Commutative PropertyBy the commutative property of fields, for any two elements ([tex]a,\, b\in \mathbb{R}[/tex]) of the real number field [tex](\mathbb{R},\, +,\, \cdot)[/tex]:
[tex]a + b = b + a[/tex].
[tex]a \cdot b = b \cdot a[/tex].
The commutative property of fields allow the elements in the additions and in multiplications to be rearranged. (In contrast, the associative property allows for only the rearrangement of the parentheses.)
That doesn't apply to [tex](2+ x) + 3 = 2 + (x + 3)[/tex] because the numbers and symbols appear in the same order on both sides of the equation.

associative property

Yancey Smith works part-time as a sales assistant. Last week
he earned $240.00. This week he earned $325.00. Yancey is
single and claims 2 allowances. Using the percentage method,
how much more will be withheld this week for federal
income tax?
The required amount to be held this week for federal tax is $12.75.
Here,
Last week's earnings = $240
Difference with marked amount = $240 - $195 = $45
This comes under type 2
So tax = 14 + 15% of 45
tax = 14.40 + 6.75
tax = $21.15
This week's earnings = $325
The difference with marked amount = $325 - $195 = 130
Tax = 14 + 15% of 130
Tax = 14.40 + 19.5
Tax = 33.9
the amount held this week = 33.9 - 21.15
= $12.75
Thus, the required amount to be held this week for federal tax is $12.75.
