Hope this helps. Pls give brainliest.

Step-by-step explanation:

2x+4y=8

3x-4y=12

2x+4y+3x-4y=8+12

cancel +4y and -4y

therefore 2x+3x=20

5x=20

x=20/5

x=4

Sibstituting x=4 in 2x+4y=8

2x+4y=8

2*4+4y=8

8+4y=8

4y=8-8

y=0/4

y=0

x=4

y=0

Answer:

[tex]m=-\frac{2}{3}[/tex]

Step-by-step explanation:

Taking any two points on the line to find the slope

Let us find the slope between the two points we took from the line graph

[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]\left(x_1,\:y_1\right)=\left(6,\:-3\right),\:\left(x_2,\:y_2\right)=\left(-6,\:5\right)[/tex]

[tex]m=\frac{5-\left(-3\right)}{-6-6}[/tex]

[tex]m=-\frac{2}{3}[/tex]

Answer:

The slope of a line that is perpendicular to the line

y = -1/8x +3​ will be: 8

Step-by-step explanation:

Given the equation

y = -1/8x +3​

comparing the equation with the slope-intercept form

[tex]y=mx+b[/tex]

Here,

so the slope of the line is -1/8.

As we know that the slope of the perpendicular line is basically the negative reciprocal of the slope of the line, so

The slope of the perpendicular line will be:

[tex]\frac{-1}{\frac{-1}{8}}=8[/tex]      ∵ [tex]\mathrm{Apply\:the\:fraction\:rule}:\quad \frac{1}{\frac{b}{c}}=\frac{c}{b}[/tex]

Therefore, the slope of a line that is perpendicular to the line

y = -1/8x +3​ will be: 8

Answer:

B

Step-by-step explanation:

The system of the equation that has only one solution is; 5x-4y=8 and  3x+2y=8.

A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.

We have to determine;

Which system of equations has only one solution

As per the question,  a system of linear equations can have one solution if there is only one point that makes every equation in the system true.  It implies that there is one point that can satisfy all of the equations at the same time.

The system of equations has only one solution is;

5x-4y=8

3x+2y=8

from equation 1

5x-4y=8

5x=8+4y

[tex]x=\frac{8+4y}{5}[/tex]

Putting the value of x in equation 2

3x+2y=8

[tex]3(\frac{8+4y}{5})+2y=8[/tex]

[tex](\frac{24+12y}{5})+2y=8[/tex]

24+12y+10y=[tex]5*8[/tex]

24+22y=40

22y=40-24

22y=16

y=[tex]\frac{16}{22}[/tex]

y=[tex]\frac{8}{11}[/tex]

Putting the value of b in equation 1,

3x+2y=8

3x+2[tex]\frac{8}{11}[/tex]=8

3x=8-[tex]\frac{16}{11}[/tex]

3x=[tex]\frac{88-6}{11}[/tex]

[tex]x=\frac{82}{33}[/tex]

Therefore, the system of equation which has exactly one solution are;

5x-4y=8 and  3x+2y=8.

Answer:

x-5+ [tex]\frac{3}{x+2}[/tex]

Step-by-step explanation:

If x+2 is a factor, -2 is a zero. So we can put -2 in the left-hand corner of your synthetic division, bring the coefficients down so you'll have a set up like this:

-2 |   1    -3    -7

____________

1. bring down the 1:

-2 |   1    -3    -7

____________

       1

2. multiply that by -2 and enter the result underneath 3:

-2 |   1    -3    -7

             -2

___________

       1

a. then, add through:

-2 |   1    -3    -7

             -2

___________

       1     -5

3. Do the same for -5 (multiply by the zero -2), enter that underneath -7 and add through:

-2 |   1    -3    -7

             -2    10

___________

       1     -5    3

Now, reassign the coefficients to their x. Because we already factored out an x with the zero, the 1 is assigned to 'x' rather than back to '[tex]x^{2}[/tex]'. The '-5' will not have an x attached. '3' is your remainder and cannot be divided out any further, so it will be written as [tex]\frac{3}{x+2}[/tex]. Finally, just put them back together to get x-5+[tex]\frac{3}{x+2}[/tex].

Hope this helped!

Answer:

3/4=n/8

Step-by-step explanation:

An equation to represent the given scenario is 3/4 = n/8. Therefore, option A is the correct answer.

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

Given that, mix 3 liters of water with 4 lemons to make lemonade.

Let n be the number of liters of water mixed with 8 lemons.

So, an equation is 3/4 = n/8

3/1 = n/2

n=6

Therefore, option A is the correct answer.

Answer:

Please check the explanation.

Step-by-step explanation:

As an airplane travels 780 miles in 4 hours.

We need to determine the table and graph to show the mileage for 2,8 and 12 hours.

as

The airplane covers the distance in 4 hours: 780 miles

so

The airplane covers miles in 1 hour will be: 780/4 = 195 miles

Hence, the table can be calculated as:

Hours                             Distance Mileage in Miles

[tex]2[/tex]                                       [tex]2\times195\:=\:390[/tex] miles

[tex]8[/tex]                                       [tex]8\times195 = 1560[/tex] miles

[tex]12[/tex]                                     [tex]12\times195 = 2340[/tex] miles

It is clear from the table that it is a direct variation as the constant is 195 miles per hour.

Please check the attached graph. The graph clearly indicates a direct variation.

Given the expression what Lizzet said was correct

[tex]6^3\times \:\:3^6=18^8[/tex]

No, she is not right. Let me solve the expression

Let us solve the expression

[tex]6^3\times \:\:3^6[/tex]

[tex]=\left(3\times \:2\right)^3\times \:3^6[/tex]

[tex]\mathrm{Apply\:exponent\:rule}:\:\:\:\left(ab\right)^c=a^cb^c[/tex]

[tex]=3^3\times \:2^3\times \:3^6[/tex]          ∵  [tex]\left(3\times \:2\right)^3=3^3\times \:2^3[/tex]
