Lyle can paint a room in 3 hours. Selena can paint a room with the same dimensions in 2 hours. If they work together, how many hours does it
take them to paint the room? Round your answer to the nearest tenth

the solution is x=1

step-by-step explanation:

we are given our   equation as

let's assume

left side function is

right side function is

now, we can draw graph

and then we can get intersection point

the intersection point will be solution

so, the solution is

x=1

150

step-by-step explanation:

the terms in pattern b are 4 times the terms in pattern a

so part 1: the y values stay the same, but the x values are opposite signs.

part 2 & 3: the line will be of equal lengths and will be straight.

part 4: you'd see the same characteristic because the x coordinate becomes a negative making them at equal distances from the y axis?
