This is a pre-algebra problem. I'll go through the steps with you. If you don't get it, don't be afraid to ask!
Step One - Cross Multiply
These are fractions, but that doesn't mean you have to add them. Fractions are just the numerator divided by the denominator. So to 'remove' the 9, multiply both sides by 9. To 'remove' the 6, multiply both sides by 6. (We multiply both sides of the equation by the same number because we need to make each side the same). Note that when you multiply both sides by 9 or 6, you have to multiply the whole part.
(2x+1)×6 = (1-1)×9
Distribute.
12x+6 = 9-9
Step Two - Solve the Equation
So we are left with this equation after cross multiplying:
12x+6 = 9-9
First, we can start by subtracting 9 from 9, because those are the same types of numbers.
12x+6 = 0
Now, we have to 'remove' the 6. We can do that by subtracting each side by 6.
(12x+6)-6 = 0-6
12x = -6
Now we are left this this.
We need to 'remove' the 12 now, so we can isolate the x. Since 12 is multiplied to x, we divide each side by 12.
(12x)÷12 = -6÷12
We get x = -1/2
x = -1/2 or -0.5
Hope this helped!

I and 42
9y= -402
Answers
y = -2/3x
So we plug in y = -2/3x for the value of y in the equation we need to solve.
4x - 9(-2/3x) = -40 (9 • -2/3x = -6x)
4x - (-6x) = -40 Multiply together
4x + 6x = -40 Combine like terms
10x = -40 Isolate x

Identify a and b for the hyperbola with equation. (y^2/b^2)-(x^2/a^2)=1
Answers
The value of (a) and (b) for the hyperbola are [tex]\sqrt 3[/tex] and 2
The equation of the hyperbola is given as:
[tex]\frac{y^2}{b^2} - \frac{x^2}{a^2} = 1[/tex]
The curve of the graph passes through points (0,2) and (-4,3).
So, we have:
[tex]\frac{2^2}{b^2} - \frac{0^2}{a^2} = 1[/tex] and [tex]\frac{(-4)^2}{b^2} - \frac{3^2}{a^2} = 1[/tex]
[tex]\frac{2^2}{b^2} - \frac{0^2}{a^2} = 1[/tex] becomes
[tex]\frac{4}{b^2} = 1[/tex]
Cross multiply
[tex]b^2 = 4[/tex]
Take positive square root of both sides
[tex]b = 2[/tex]
[tex]\frac{(-4)^2}{b^2} - \frac{3^2}{a^2} = 1[/tex] becomes
[tex]\frac{(-4)^2}{2^2} - \frac{3^2}{a^2} = 1[/tex]
[tex]\frac{(-4)^2}{4} - \frac{9}{a^2} = 1[/tex]
[tex]4 - \frac{9}{a^2} = 1[/tex]
Collect like terms
[tex]- \frac{9}{a^2} = -3[/tex]
Cross multiply
[tex]-3a^2 = -9[/tex]
Divide both sides by -3
[tex]a^2 = 3[/tex]
Take square roots of both sides
[tex]a = \sqrt 3[/tex]
Hence, the value of (a) and (b) for the hyperbola are [tex]\sqrt 3[/tex] and 2

Use the Distributive Property to solve the equation. 3x-5(x-4)=-9+5x+15
Answers
Answer:
I keep getting no solution
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
5(x−4)=−9+5x+15
(5)(x)+(5)(−4)=−9+5x+15(Distribute)
5x+−20=−9+5x+15
5x−20=(5x)+(−9+15)(Combine Like Terms)
5x−20=5x+6
5x−20=5x+6
Step 2: Subtract 5x from both sides.
5x−20−5x=5x+6−5x
−20=6
Step 3: Add 20 to both sides.
−20+20=6+20

Which equation is parallel to
y =2/3x – 6 and passes through (9, -3)?
Answers
Answer:
y=2/3x -3
Step-by-step explanation:
y=mx+c
If the gradient(m) is the same then it's parallel.
The line passes through -3 so the y intercept(c) is -3
Answer:
Y=2/3x-9
Step-by-step explanation:
Y=mx+c
y=2/3x+c
Then substitute the coordinates
y=-3
x=9
-3=2/3*(9)+c
-3=6+c
Make c the subject by subtracting 6 from both sides.
-9=c
so the answer is
Y=2/3x-9

Write out the form of the partial fraction decomposition of the function (as in this example). A) x4 − 2x3 + x2 + 2x − 1/x2 − 2x + 1B) x2 - 1/x3 + x2 + x
Answers
Answer:
A. [tex]\mathbf{\dfrac{x^4-2x^3+x^2+2x-1}{x^2-2x+1 }= x^2 + \dfrac{A}{x-1}+ \dfrac{B}{(x-1)^2}}[/tex]
B. [tex]\mathbf{\dfrac{x^2-1}{x(x^2+x+1)} = \dfrac{A}{x}+ \dfrac{Bx+C}{x^2 +x+1}}[/tex]
Step-by-step explanation:
A.
Given that:
[tex]\dfrac{x^4 -2x^3 +x^2+2x -1}{x^3 -2x +1}[/tex]
[tex]\dfrac{x^4 -2x^3 +x^2+2x -1}{x^3 -2x +1} =\dfrac{(x^4 -2x^3+x^2) +(2x-1)}{x^3 -2x +1}[/tex]
[tex]=\dfrac{(x^4 -2x^3+x^2)}{x^3 -2x +1} + \dfrac{(2x-1)}{x^3 -2x +1}[/tex]
[tex]= \dfrac{x^2(x^2-2x+1)}{x^2-2x+1}+ \dfrac{2x-1}{(x-1)^2}[/tex]
[tex]\dfrac{x^4-2x^3+x^2+2x-1}{x^2-2x+1 }= x^2 + \dfrac{2x-1}{(x-1)^2}---(1)[/tex]
Further, the partial fraction decomposition of [tex]\dfrac{2x-1}{(x-1)^2}[/tex] can be written as:
[tex]\dfrac{2x-1}{(x-1)^2} = \dfrac{A}{x-1}+ \dfrac{B}{(x-1)^2}[/tex]
From equation one, replacing the values; we have the partial fraction decomposition of the function to be:
[tex]\mathbf{\dfrac{x^4-2x^3+x^2+2x-1}{x^2-2x+1 }= x^2 + \dfrac{A}{x-1}+ \dfrac{B}{(x-1)^2}}[/tex]
B.
Given that:
[tex]\dfrac{x^2-1}{x^3+x^2+x}[/tex]
[tex]\dfrac{x^2-1}{x^3+x^2+x} = \dfrac{x^2-1}{x(x^2+x+1)}[/tex]
Therefore, the partial fraction of decomposition is:
[tex]\mathbf{\dfrac{x^2-1}{x(x^2+x+1)} = \dfrac{A}{x}+ \dfrac{Bx+C}{x^2 +x+1}}[/tex]

Which graph represents y as a function of x?
Answers
Answer:
The third picture (shown below as an attachment)
Step-by-step explanation:
This problem wants us to detect which one is a function. The definition of a function is that for every x-value you input into the function, you will get ONLY ONE y-value output. A way to check this when it’s graphed is to scan left to right (vice versa) and if there are two lines that meet at the same x-values, then it’s not a function. We can eliminate the circle graph because there are two lines that meet the x-coordinates. Like how when x is -5, the y-coordinate is both 7 and -7. This proves that for the x-coordinate -5, the y-coordinate has two y-coordinates, 7 and -7. Therefore, the circle graph is not a function. Same thing for the absolute value graph (the v-shape graph). There are two lines that overlap on the x-values. The last graph (the straight vertical line) is definitely not a function because all y-values are equal to the x-value 3, which means that multiple y-values share an x-coordinate. The third option (the correct one) is a function because there are no overlapping lines. You might say that when x is 1, there are two y-coordinates, 4 and -4. But the higher line has an open circle at 4 which means that the line doesn’t include 4. So they don’t overlap, which makes it a function. Choose the graph of option three (the attached picture).
I hope you understand.
Hope this helps and answers your question :)
The third graph represents y as a function of x.
What is a function?A relation is a function if it has only One y-value for each x-value.

A way to check this when it’s graphed is to scan left to right (vice versa) and if there are two lines that meet at the same x-values, then it’s not a function.
We can eliminate the circle graph because there are two lines that meet the x-coordinates.
For second graph there are two lines that overlap on the x-values.
The last graph (the straight vertical line) is definitely not a function because all y-values are equal to the x-value 3, which means that multiple y-values share an x-coordinate.
The third option (the correct one) is a function for each value of y there is one x value.

Answers
The equation that best suits the scatter plot is y = x - 0.5.
A straight line graph has the general equation; y = mx + c Where; m = slope, c = y- intercept. We now have to examine each of the equations as written so as to determine which of the equations that best suits the scatter plot as shown.
First of all, we can see that the line did not start from origin. Looking at the graph very closely, we can conclude that the equation that best suits the scatter plot is y = x - 0.5.
