For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of both denominators - LCM(3, 4) = 12. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 3 × 4 = 12. In the following intermediate step, cancel by a common factor of 2 gives 5/

.
In other words - one third plus two quarters = five sixths.
Add:1 + 1/2 = 5/6 + 1/2 = 5/6 + 1 · 3/2 · 3 = 5/6 + 3/6 = 5 + 3/6 =8/6 = 2 · 4/2 · 3 = 4/3

First convert the mixed fractions to improper fractions.
[tex](5\dfrac{2}{3})^{2}-(4\dfrac{1}{3})^{2} = (\dfrac{17}{3})^{2} - (\dfrac{13}{3})^{2}[/tex]
We can use the identity a² - b² = (a +b)(a - b)
Here a = 17/3 and b = 13/3
[tex]= (\dfrac{17}{3}+\dfrac{13}{3})(\dfrac{17}{3}-\dfrac{13}{3})[/tex]
We can add & subtract as they have common denominators.
[tex]=\dfrac{30}{3}*\dfrac{14}{3}\\\\= 10*\dfrac{14}{3}\\\\\\=\dfrac{140}{3}\\\\\\= 46\dfrac{2}{3}[/tex]

What is the y-intercept ??? Please show step by step!!
Answers
Answer:
(0, 1)
Step-by-step explanation:
The y-intercept is where a graph intersects with the y-axis. The x-coordinate would be 0, and the y-coordinate would be any real number.
Given the information above, the y-intercept is (0, 1) or 1 because its x-coordinate is 0 and y-coordinate is a real number.
Answer:
y-intercept is (0,1)
Step-by-step explanation:
When we are looking at the chart we’re looking for a point where the x is 0 and the y is 1 which is the definition of y-intercept, where the line intersects only with the y-axis
We can see this in the chart but if that point is not on there, we have another way to find it.
This is the formula, point-slope form.
(Math people are not that creative, you use it when you have the slop and a point)
First, we need to find the slope
We do this by taking two points and using the formula y2-y1 over (/) x2-x1
So our formula is y2-y1/x2-x1.
If you pick two random points, (We will use 0,1 and 1,3) and subtract them from each other, you have the slope
3 is y2 because it’s a y point and its the second point and 1 is our other point because its a y point and its the first y point
So our equation now is 3-1/x2-x1
Now we have to sub in for the x’s
Do the same thing and our equation now is…
3-1/1-0
This gets us to 2/1 which is obviously 2.
Now we have our slope so we just have to fill in for the point.
Point slope form uses the model y-y1=m(x-x1)
So we use our same two points and get
Y-1=2(x-0)
Solve this out to Slope intercept form which will give us our y-intercept.
This gets us to y=2x+1 so our y-intercept is clearly still 1!

Solve the system of equations:
x+3y-z=9
2x+9y+4z=12
x+4y+z=7
Answers
[i] … … … x + 3y - z = 9
[ii] … … … 2x + 9y + 4z = 12
[iii] … … … x + 4y + z = 7
Eliminate z by combining …
• … 4 times equation [i] and equation [ii] :
4 (x + 3y - z) + (2x + 9y + 4z) = 4•9 + 12
(4x + 12y - 4z) + (2x + 9y + 4z) = 36 + 12
6x + 21y = 48
2x + 7y = 16
• … equation [i] and equation [iii] :
(x + 3y - z) + (x + 4y + z) = 9 + 7
2x + 7y = 16
Since we ended up with 2 copies of the same equation, we have infinitely many solutions for x, y, and z. That is, we have infinitely many choices for x and y that satisfy 2x + 7y = 16, and consequently infinitely many choices for z to satisfy any of the 3 original equations.
We can parameterize the solution by letting, for instance, x = t; then the solution set is
x = t
2x + 7y = 16 ⇒ y = (16 - 2t)/7
x + 3y - z = 9 ⇒ z = t + 3 (16 - 2t)/7 - 9 ⇒ z = (t - 15)/7
where t is any real number.

Problem 2: Use the Laplace Transforms to solve:
[tex]y'' - y' - 2y= 1 - x , \\ y(0) =y'(0) =1[/tex]
Answers
Using the given table of transforms,
[tex]L\left\{ y'' - y' - 2y \right\} = L\left\{ 1-x \right\}[/tex]
[tex](s^2 Y(s) - sy(0) - y'(0)) - (s Y(s) - y(0)) - 2 Y(s) = \dfrac1s - \dfrac1{s^2}[/tex]
(where Y(s) is the Laplace transform of y(x))
Solve for Y(s) :
[tex](s^2 - s - 2) Y(s) - s = \dfrac1s - \dfrac1{s^2}[/tex]
[tex](s^2 - s - 2) Y(s) - s = \dfrac{s-1}{s^2}[/tex]
[tex](s^2 - s - 2) Y(s) = \dfrac{s-1}{s^2} + s[/tex]
[tex](s^2 - s - 2) Y(s) = \dfrac{s^3 + s - 1}{s^2}[/tex]
[tex]Y(s) = \dfrac{s^3 + s - 1}{s^2 (s^2 - s - 2)}[/tex]
[tex]Y(s) = \dfrac{s^3 + s - 1}{s^2 (s + 1) (s - 2)}[/tex]
Decompose the right side into partial fractions:
[tex]Y(s) = \dfrac as + \dfrac b{s^2} + \dfrac c{s+1} + \dfrac d{s-2}[/tex]
Solve for the coefficients.
[tex]\implies s^3 + s - 1 = as(s+1)(s-2) + b(s+1)(s-2) + cs^2(s-2) + ds^2(s+1)[/tex]
[tex]\implies s^3 + s - 1 = -2 b + (-2 a - b) s + (-a + b - 2 c + d) s^2 + (a + c + d) s^3[/tex]
[tex]\implies \begin{cases}-2b = -1 \\ -2a-b = 1 \\ -a+b-2c+d = 0 \\ a+c+d = 1 \end{cases} \implies a=-\dfrac34, b=\dfrac12, c=1, d=\dfrac34[/tex]
Then
[tex]Y(s) = -\dfrac34 \times \dfrac1s + \dfrac12 \times \dfrac1{s^2} + \dfrac1{s+1} + \dfrac34 \times\dfrac1{s-2}[/tex]
Take the inverse transform and solve for y(x) :
[tex]F(s) = \dfrac1s \implies f(x) = 1[/tex]
[tex]F(s) = \dfrac1{s^2} \implies f(x) = x[/tex]
Using the frequency-shifting property,
[tex]F(s) = \dfrac1{s+1} \implies f(x) = e^{-x}[/tex]
[tex]F(s) = \dfrac1{s-2} \implies f(x) = e^{2x}[/tex]
So, the particular solution to the ODE is
[tex]\boxed{y(x) = -\dfrac34 + \dfrac x2 + e^{-x} + \dfrac{3e^{2x}}4}[/tex]

Therefore, Y=7 is the answer.
Answer:
y = 7
Step-by-step explanation:
Linear equation: y = mx + b

Answers
Answer:
Step-by-step explanation:
As we can see that Line WL is a straight line that the angles that make up it like Angle HJW and Angle GJH and Angle LJG all equal to 180 degrees
Angle HJW = 18 degrees
ANGLE GLH = 90 degrees (we know that because there is a little square)
Angle LJG = 9x
Now lets set up the equation:
Angle HJW + Angle GLH + ANGLE LJG = 180 degrees
18 + 90 + 9x = 180
108 + 9x = 180
9x = 72
x = 8
So x = 8
