Question

draw the graph of 9 x minus 5 y plus 160 = 20 from the graph find the value of Y when x = 25 ​

Answer 1

Answer:

when x = 5 then y = 41

Step-by-step explanation:

We are given that

9x -5y + 160 = 0

If x = 5 then

9(5) -5y + 160 = 0

45 - 5y + 160 = 0

                5y = 205

                 y = 41

And you can see in the graph below we have the same solution for y that is 41.01 which is approximation due to the software accuracy.

And it is the linear equation we can find some more solution like

When

x = 2

9(2) -5y + 160 = 0

18 -5y + 160 = 0

5y = 178

y = 35.6

When

x = -15 then y = 5

When

x = 17.78 then y = 0

When

x = 0 then  y = 32
