Solve the system by graphing. What is the solution of y=-x+4 and y=3/5x+4

Mathematics
1 answer:
dlinn [17]3 years ago

Answer:

x=0 and y=4 thats where the points meet

Step-by-step explanation:

solution of x and y:

both equations equal to y so you can put them together

3/5x+4=-x+4

separate the variables and numbers...

1.6x=0

x=0

y=4

if ur using a graph, use the y intercept (0,4) for your first point

then, using y=-x+4, make -x a fraction -1/1

by using rise/run go down one unit from (0,4) since its negative 1

then one unit to the right from where you are

you should be able to connect the points for the first equation

find the second equation on your own now:)

Ok. 1/4 is 9/36 . you do this by seeing what will give you 36 when you have a 4 . and 9/9 when you divided both you get 0.25.

again we have 4/9 and we see what we can put in to get another 36 , but we have a 9, so it’s 4. 4/9 x 4/4 = 16/36 when you divide this you them both you get 0.44 so they’re equivalent.


so 0.25 is less than 0.44

basically it’s saying 25<44

so 1/4 is less than 4/9
