[tex]10x+10-10=10-10[/tex] [tex]10x=0[/tex]Step 3: Divide both sides by 10.
[tex]10x/10=0/10[/tex] [tex]x=0[/tex]Have a lovely rest of your day/night, and good luck with your assignments! ♡
Write an equation in slope-intercept form for the line that satisfies each set of conditions.
parallel to y=2/3x - 10, x intercept at 9
Answer: Y= 2/3x + 9
Explanation: The equation is in slope-intercept form, y=mx+b. Since it is parallel to the equation, it has the same slope (2/3x) and since b is the x intercept, b is 9.
The equation in slope-intercept form for the line that is parallel to y=(2/3)x-10 and x-intercept at 9 is y =
What is a Linear Equation of a line?
A linear equation is an algebraic equation of the form y=m x + b. involving only a constant and a first-order (linear) term, where m is the slope and b is the y-intercept
Parallel lines have the same slope.
Given data ,
The x-intercept is obtained when we set the value y = 0
As the x-intercept is 9 , therefore the point representing the x-intercept will be: ( 9 , 0 )
Now , the equation of line is given by y = m x + c
And , y = ( 2 / 3 ) x - 10
Since the lines are parallel , they will have same slope
So , the equation in slope intercept for the line will be
y = ( 2 / 3 ) x + 9
Hence the equation of line will be y = ( 2 / 3 ) x + 9

Allie is single, has an adjusted gross income of $25,005 and one exemption of $12400. How much is his tax according to the table? Hint: find taxable income first. $1246 $1263 $1318 $1324
Allie's tax amount is the amount deducted from his taxable income
Allie's tax amount is $1427
How to determine the tax?The given parameters are:
Adjusted gross income = $25,005
Exemption = $12400
Start by calculating the taxable income using
Taxable income = Adjusted gross income - Exemption
So, we have:
Taxable income = $25,005 - $12400
Evaluate the differences
Taxable income = $12605
The question is incomplete.
So, I will use the table of the single taxable income tax bracket and rates, 2016
Using the table, the tax amount on an income of $12605 is:
Tax = $927.50 + 15% * (Amount - $9275)
So, we have:
Tax = $927.50 + 15% * ($12605 - $9275)
Evaluate
Tax = $1427
Hence, Allie's tax amount is $1427

A square is cut into two identical rectangles. Find the perimeter of each rectangle if the perimeter of the square is 48 cm.
thankyou ~
Solution:
perimeter of rectangle = 2 ( Length + Width )
a square has all sides of similar length. thus [ length = width ]Find length/width:
2 (length + length) = 48
2(length) = 24
length = 12 cm
width = 12 cm
⇒ The dimensions of square: 12 x 12
If the square cut into half, the dimensions of either length or width will half.
Therefore, the perimeter of rectangle:
→ 2 (length + width)
→ 2 ( 12 + 6 )
→ 2 ( 18 )
→ 36 cm
(9x + 4) (2x2 – 17x - 9) = 0
-
Step-by-step explanation:
So leave (9x+4) and factor (2x2-17x-9) .
Factors into (2x+1)(x-9).
Now set (9x+4)=0 and find x. x= -4/9
set (2x+1)=0 x = -1/2
set x-9=0 so x=9. you have 3 solutions which are -4/9, -1/2, and 9.

7b+2 b = 2
3(2c-10)
1+2.1y-0.9y+4
Answer:
If you were to solve for, 7b+ 2b = 2 then;
7b+ 2b = 2
Combine like terms first:
(7b + 2b)
9b = 2
Then divide by 9 from both sides to solve for b:
/9 /9
b = 2/9 or 0.222..
If you were to solve for, 3(2c - 10) then;
3(2c - 10)
Use the distributive property, and multiply 3 to both 2c and 10:

Stephen, Paul & Bridget share some money in the ratio 3 : 4 : 2.
In total, Stephen and Bridget receive £50.
How much does Paul get?
Answer:
£40.
Step-by-step explanation:
In terms of ratio units, Stephen and Bridget together get 3+2 = 5, while Paul receives 4. That is, Paul gets 4/5 of their combined total, or ...
4/5 · £50 = £40
Paul gets £40.
Given parameters:
Ratio of their money = 3 : 4 : 2
Total amount received by Stephen and Bridget = 50
Unknown :
How much did Paul get = ?
Solution:
The amount Paul got is a fraction of the total.
We need to find the total amount first;
Amount Stephen and Bridget got = [tex]\frac{ratio of stephen and bridget}{total ratio} x total amount[/tex]
let the total amount = y;
50 = [tex]\frac{3+2}{9}[/tex] x y
[tex]\frac{5y}{9}[/tex] = 50
5y = 450
y = 90
Now, the amount Paul got;
= [tex]\frac{4}{9} x 90[/tex]
= 40
The amount Paul got is £40

Write a matrix representing the system of equations
Answer:
[tex](4, -1, 3)[/tex]
Step-by-step explanation:
We have the system of equations:
[tex]\left\{ \begin{array}{ll} x+2y+z =5 \\ 2x-y+2z=15\\3x+y-z=8 \end{array} \right.[/tex]
We can convert this to a matrix. In order to convert a triple system of equations to matrix, we can use the following format:
[tex]\begin{bmatrix}x_1& y_1& z_1&c_1\\x_2 & y_2 & z_2&c_2\\x_3&y_2&z_3&c_3 \end{bmatrix}[/tex]
Importantly, make sure the coefficients of each variable align vertically, and that each equation aligns horizontally.
In order to solve this matrix and the system, we will have to convert this to the reduced row-echelon form, namely:
[tex]\begin{bmatrix}1 & 0& 0&x\\0 & 1 & 0&y\\0&0&1&z \end{bmatrix}[/tex]
Where the (x, y, z) is our solution set.
Reducing:
With our system, we will have the following matrix:
[tex]\begin{bmatrix}1 & 2& 1&5\\2 & -1 & 2&15\\3&1&-1&8 \end{bmatrix}[/tex]
What we should begin by doing is too see how we can change each row to the reduced-form.
Notice that R₁ and R₂ are rather similar. In fact, we can cancel out the 1s in R₂. To do so, we can add R₂ to -2(R₁). This gives us:
[tex]\begin{bmatrix}1 & 2& 1&5\\2+(-2) & -1+(-4) & 2+(-2)&15+(-10) \\3&1&-1&8 \end{bmatrix}\\\Rightarrow\begin{bmatrix}1 & 2& 1&5\\0 & -5 & 0&5 \\3&1&-1&8 \end{bmatrix}[/tex]
Now, we can multiply R₂ by -1/5. This yields:
[tex]\begin{bmatrix}1 & 2& 1&5\\ -\frac{1}{5}(0) & -\frac{1}{5}(-5) & -\frac{1}{5}(0)& -\frac{1}{5}(5) \\3&1&-1&8 \end{bmatrix}\\\Rightarrow\begin{bmatrix}1 & 2& 1&5\\ 0 & 1 & 0& -1 \\3&1&-1&8 \end{bmatrix}[/tex]
From here, we can eliminate the 3 in R₃ by adding it to -3(R₁). This yields:
[tex]\begin{bmatrix}1 & 2& 1&5\\ 0 & 1 & 0& -1 \\3+(-3)&1+(-6)&-1+(-3)&8+(-15) \end{bmatrix}\\\Rightarrow\begin{bmatrix}1 & 2& 1&5\\ 0 & 1 & 0& -1 \\0&-5&-4&-7 \end{bmatrix}[/tex]
We can eliminate the -5 in R₃ by adding 5(R₂). This yields:
[tex]\begin{bmatrix}1 & 2& 1&5\\ 0 & 1 & 0& -1 \\0+(0)&-5+(5)&-4+(0)&-7+(-5) \end{bmatrix}\\\Rightarrow\begin{bmatrix}1 & 2& 1&5\\ 0 & 1 & 0& -1 \\0&0&-4&-12 \end{bmatrix}[/tex]
We can now reduce R₃ by multiply it by -1/4:
[tex]\begin{bmatrix}1 & 2& 1&5\\ 0 & 1 & 0& -1 \\ -\frac{1}{4}(0)&-\frac{1}{4}(0)&-\frac{1}{4}(-4)&-\frac{1}{4}(-12) \end{bmatrix}\\\Rightarrow\begin{bmatrix}1 & 2& 1&5\\ 0 & 1 & 0& -1 \\0&0&1&3 \end{bmatrix}[/tex]
Finally, we just have to reduce R₁. Let's eliminate the 2 first. We can do that by adding -2(R₂). So:
[tex]\begin{bmatrix}1+(0) & 2+(-2)& 1+(0)&5+(-(-2))\\ 0 & 1 & 0& -1 \\0&0&1&3 \end{bmatrix}\\\Rightarrow\begin{bmatrix}1 & 0& 1&7\\ 0 & 1 & 0& -1 \\0&0&1&3 \end{bmatrix}[/tex]
And finally, we can eliminate the second 1 by adding -(R₃):
[tex]\begin{bmatrix}1 +(0)& 0+(0)& 1+(-1)&7+(-3)\\ 0 & 1 & 0& -1 \\0&0&1&3 \end{bmatrix}\\\Rightarrow\begin{bmatrix}1 & 0& 0&4\\ 0 & 1 & 0& -1 \\0&0&1&3 \end{bmatrix}[/tex]
Therefore, our solution set is [tex](4, -1, 3)[/tex]

d) m∠a = m∠f
Step-by-step explanation:
Where a transversal crosses parallel lines, certain relationships between the angles are established. Effectively, the two same-side interior angles are supplementary, as they would be in a parallelogram. Here, those are angles B and F, or angles A and E.
The vertical- and linear-angle relationships give rise to all of the other ways this is expressed. For example, angles A and B are a linear pair, so supplementary. Since B and F are supplementary, and B and A are supplementary, F = A. Using more formal language, ...
m∠a = m∠f
