Answer:

He buys 8 desks and 6 chairs can i have branliest

Step-by-step explanation:

Set up a system of equations

desks = y chairs = x

x+y=14

125x + 515y = 4870

Eliminate,

-125x -125y = -1750

125x + 515 y = 4870

390 y = 3120

y = 8

substitute in 8

x + 8 = 14

x = 6

Answer:

Step-by-step explanation:

Let number of chairs be x and number of desks be y

Total number of chairs and desks = 14

x + y = 14   --------------(i)

Total cost  = $ 4870

125x + 515y = 4870 ------------(ii)

Multiply equation (i) by (-125).

(i)*(-125)          -125x - 125y = -1750

(ii)                    <u>125x +515y = 4870</u>    {Now add}

                                  390y = 3120

y = 3120/390

y = 8

Plug in value of y in equation 1

x + 8 = 14

x = 14 - 8

x = 6

Number of chairs = 6

Number  of desks  = 8

Graph the line with slope <br> 3/4<br><br><br> passing through the point (1,4)<br><br><br> .
Valentin [98]

To graph the line, we must first find out the equation for the line in slope-intercept form (y = mx + b). So far, we only have the slope, so the line's equation is y = 3/4x + b. But, by inserting the values of x and y in the point we know, we can find the y - intercept.


4 = 3/4 + b


b = 13/4


That means that the equation of our line is y = 3/4x + 13/4. Now we can graph. But, there is another way to go about (slightly faster too). Since we know the coordinates of 1 point, we can put that line down. Then, since we know that slope is rise over run, we can say, that with a slope of 3/4, one would go 3 points up for every 4 to the right. Now we can go 3 points up and 4 points to the right of point (1,4). That would be (5, 7). Now we can graph (since we have 2 points, or an equation).


The graph looks like this:

5.1 kilometers to meters and centimeters
Snezhnost [94]
Hey there 

1 km = 1000 meters 
So 5 km will equal 5000 meters 
.1 will equal  100 meters 

5.1 km = 5100 meters 

<span>100,000 centimeters = 1 kilometer 
</span>5.1 km = 510000 centimeters 

Hope this helps

Systems By Graphing - Solve All Correctly For a Thanks, 5-Stars, And A Brianliest!
BartSMP [9]

Answer:

Step-by-step explanation:

Amari= Graph C and Solution is (-6,-2)

Bella= Graph A and Solution is (3,4)

Carl= Graph B and Solution is (0,-3)

0 solutions because the slopes are the same. The lines will never cross because they are at the exact same angle.

No, I do not agree with Joey because the lines have different slopes and will lead to the system cross which is the solution.

1st graph: y=2x-1 and y=7 solution #1= (4,7)

2nd graph: y=-2x-3 and y=1/2x solution #2= (-2,1)

3rd graph: y=x and y= -1/5+6 solution #3= (5,5)

I had this exact same assignment a few months ago, my teacher didn't use the 2nd slide but I had the 1st and 3rd slide so this should help!
