The answer is: " x – (x + 8) " .
{Note: The simplified form is: " -8 ."}.
_______
Step-by-step explanation:
We are given:
→ " A number decreased by the sum of the number and eight."
_______
Let "x" represent the number referred to as "a number."
_______
"{A number} decreased by {the sum of the (number and eight).}" ;
↑ ↑ ↑
"x" "(minus)" " (x + 8) " ;
_______
So; we can write this as:
_______
→ " x – (x + 8) " ;
_______
Edit—Addendum:
{Now, if are then asked to simply this expression}:
→ " x – (x + 8) " ;
_______
Then: Rewrite as:
→ " x – 1(x + 8) " ;
_______
Take note of the distributive property of multiplication:
→ " a(b + c) = ab + ac " ;
_______
Likewise:
→ " x – 1(x + 8) " ;
→ Note the: " -1(x + 8) ";
_______
→ -1(x + 8) = (-1*x) + (-1*8) ;
= (-1x) + (-8) ;
= (-1x – 8) ;
Now, bring down the " ⁺x " :
→ " x – 1x – 8 " ;
Rewrite as:
→ " 1x – 1x – 8 " ;
Simplify:
→ " 1x – 1x – 8 " ;
= " (1x – 1x) – 8 " ;
= " (0 – 8) " ;
= " -8 " ; which is the simplified form of the
given algebraic expression.
_______

Hi!
I can help you with joy! :)
First of all, "the sum of" means we add.
Let the number be r.
So, we add r and 8:
r+8
Now, "decreased" means we subtract, so we subtract
r-(r+8) (Final Answer)
Simplified Form:
r-(r+8)
r-r+8

Find the area of the shaded region.
Answer:
Area of the shaded region is 104.96 m².
Step-by-step explanation:
Firstly, finding the area of circle with radius 8 cm by substituting the values in the formula :
[tex]{:\implies{\tt{A_{(Circle)} = \pi {r}^{2}}}}[/tex]
[tex]{:\implies{\tt{A_{(Circle)} = 3.14{(8)}^{2}}}}[/tex]
[tex]{:\implies{\tt{A_{(Circle)} = 3.14{(8 \times 8)}}}}[/tex]
[tex]{:\implies{\tt{A_{(Circle)} = 3.14{(64)}}}}[/tex]
[tex]{:\implies{\tt{A_{(Circle)} = 3.14 \times 64}}}[/tex][tex]{:\implies{\tt{A_{(Circle)} = 200.96 \: {m}^{2} }}}[/tex]
Hence, the area of circle is 200.96 m².
[tex]\begin{gathered}\end{gathered}[/tex]
Secondly, finding the area of rectangle with length and breadth by substituting the values in the formula :
[tex]{:\implies{\tt{A_{(Rectangle)} = l \times b}}}[/tex]
[tex]{:\implies{\tt{A_{(Rectangle)} = 12 \times 8}}}[/tex]
[tex]{:\implies{\tt{A_{(Rectangle)} = 96 \: {m}^{2}}}}[/tex]
Hence, the area of rectangle is 96 m².
[tex]\begin{gathered}\end{gathered}[/tex]
Now, finding the area of shaded region by substituting the values in the formula :
[tex]{:\implies{\tt{A_{(Shaded)} = A_{(Circle)} - A_{(Rectangle)}}}}[/tex]
[tex]{:\implies{\tt{A_{(Shaded)} = 200.96 - 96}}}[/tex]
[tex]{:\implies{\tt{A_{(Shaded)} = 104.96 \: {m}^{2}}}}[/tex]

Find the equation of the line that contains the point (4,-2) and is perpendicular to the line y=-2x+8.
Answer:
[tex]\frac{1}{2} x - 4[/tex]
Step-by-step explanation:
Perpendicular lines will have slopes that are the multiplicative additive inverse of each other: a line with slope 3/4 is perpendicular to a line with slope -4/3, for example. You need a line that is perpendicular to a line with slope -2 (reading that from the -2 in the -2x portion of the given equation, which is written in slope-intercept form), so your new line must have slope +1/2.
With the slope and a point, we can come up with an equation using this formula:
y - y-coordinate = slope (x - x-coordinate)
So we have y - (-2) = 1/2 (x - 4).
Simplify the equation: y + 2 = 1/2 x - 2
Subtract 2 from both sides: y + 2 - 2 = 1/2 x - 2 - 2
Simplify: y = 1/2 x - 4.

Write an equation of the circle with center (-6, 2) and diameter 10.
Answer:
it something i know that much
Step-by-step explanation:
Solution:
We know that the formula to write the equation of a circle is (x – h)² + (y – k)² = r², where:
h = x coordinatek = y-coordinater = radius of circleCenter of circle: (-6,2)First, let's find the radius of the circle. We know that the diameter of the circle is ten units. The radius is half of the diameter. This means that the radius is five units because it is half the diameter, which is ten units.
Diameter: 10 unitsRadius: 10/2 units = 5 unitsCreating the equation:
(x – h)² + (y – k)² = r²=> (x + 6)² + (y – 2)² = 5²Hence, the equation to form a circle with center (-6, 2) and diameter 10 is (x + 6)² + (y – 2)² = 5².

2 5/6 + (-1 4/12) =
Answer:
1.5 as decimal, 1 1/2 as a fraction
Step-by-step explanation:
1. convert 2 5/6 & (-1 4/12) to a improper fraction.
17/6 and -16/12
2. multiply 17/6 by 2 to match -16/12's denominator
17/6 * 2 = 34/12
We now have
34/12 + -16/12
A positive number plus a negative number is the same thing as subtraction so we remove the negative sign and replace the plus with a minus sign.
We have:
[tex]\frac{34}{12}-\frac{16}{12}[/tex]
Now solve. 34-16 = 18
our answer is 18/12
A normal distribution (X) has a mean of 100 and a standard deviation of 10.
What is the probability that X will be smaller than 80?
Use the Normal Table and keep all 4 decimal positions in your answer.
Using the normal distribution, it is found that there is a 0.0228 = 2.28% probability that X will be smaller than 80.
Normal Probability DistributionIn a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
It measures how many standard deviations the measure is from the mean. After finding the z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X.In this problem:
The mean is of [tex]\mu = 100[/tex].The standard deviation is of [tex]\sigma = 10[/tex].The probability that X will be smaller than 80 is the p-value of Z when X = 80, hence:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{80 - 100}{10}[/tex]
[tex]Z = -2[/tex]
[tex]Z = -2[/tex] has a p-value of 0.0228.
0.0228 = 2.28% probability that X will be smaller than 80.

You Are Graphing Rectangle ABCD In The Coordinate Plane. The Following Are Three Of The Vertices Of The Rectangle A(3,5) B(3,−4) C(−2,−4)
Answer:
D(-2,5)
Step-by-step explanation:
Point D has the same x coordinate as point C and has the same y coordinate as the point A
Hi!
We want to find the x and y value for point D.
We can see that point C is the same amount to the left as point D. That means they will have the same x-value.
Furthermore, we can see that point A is the same amount up as point D. That means that they will have the same y-value.
We will use the given coordinates, (x, y).
-------------------------------------------------------------------------------------------------------------
The x-value of point C is -2, and the y-value of point A is 5.
That means that the coordinates of point D are (-2, 5).
