How do i solve a system of equation by graphing

Mathematics

Hey there!


To solve a system of equation by graphing, first make sure both your equations are solved for y so that you can graph it (make sure it is in a form like: y=mx+b or y=ax^2+bx+c, etc).


Then, graph the equations on the graph, and the point where all the lines intersect would be your answer which should look like: (x,y)


However, if you have linear equations and the lines are parallel to each other, then there is no solution. If the lines graph to be the same line, then your answer would be all real solutions.

Look at picture ! Determine the number of sides for the 6th shape in this pattern.
horsena [70]

Answer: C) 8

Explanation: It seems that the first three shapes in this pattern are increasing by one side as they progress, that means they go 3 sides, 4 sides, 5 sides, etc. If this keeps going until the 6th shape, it would land on 8 sides, which is an octagon.

I hope this helps you :)

I have 30 coins consisting of nickels, dimes and quarters. The total value of the coins is $4.60. there are two more dimes than
aleksklad [387]

If you have 1 nickle, how many quarters do you have? (3)

If you have 4 nickles, you have 3 times as many quarters (3)(4) = 12

If you have n nickles, then you have 3n quarters so 3n = q, you have  a slightly different equation.

 

If you fix this equation and use substitution like you did, you can get the right answer; you can also try to work in the other information that you have - converting all coin values to cents

    5n + 10d + 25q = 460

Where can u place these at tell me
Alex777 [14]
The best thing to do is to rewrite the fractions as decimals
-2/3 is approx. equal to -0.6666667
So a little past half way (to the left) between -1 and 0
1 1/5 is 1.5 so that is right between 1 and 2

Hope this helps :)
