I need help on number 6 cuz I’m saying it’s F while my friend is saying that it’s H ‍♀️

Answer:

C. Four times a number decreased by 3

Answer:

(6,9)

Step-by-step explanation:

Y=2/3x+5

Y=x+3

2/4x + 5 = x + 3

Solve the equation

x=6

Substitute the value of x

y=6+3

Solve the equation again.

Now we know y=9

(x,y) = (6,9)

Check the solution

9=2/3 x 6 + 5

9=6+3

Simplify

Answer:

X=7.5 y=-1

Step-by-step explanation:

[tex]2x + 7y = 8 \\ 2x + y = 14[/tex]

I multiplied the equation with - 1 to than I sum it with the second one to get rid of x

[tex] - 6y = 6 \\ y = - 1[/tex]

Now you put Y in on of the equation and you get x.

[tex]2x - 1 = 14 \\ 2x = 15 \\ x = 7.5[/tex]

The given expression is solved by using subtraction.

The expression can be written as:

= 7 - 3

The difference between 7 and 3 is calculated by subtracting the smaller number (3) from the larger number (7):

= 7 - 3

= 4

Therefore,

The difference between the numbers 7 and 3 is 4.

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.

A relation is a function if it has only One y-value for each x-value.

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.

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.

Hence, the third graph represents y as a function of x.

Step-by-step explanation:

69.45

69.45 divided by 0.05

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]

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.

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

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

0=26

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
