How do you do these 3 questions?

the one on the bottom left

step-by-step explanation:

all of the other ones have a specific pattern

you have to find the same variables -3n - 5n so this would be -3n +(-5n) which equals -9n

14 x 10 5

step-by-step explanation:

10 5 = 100,000

14x10,000 = 140,000

graph #4 (last graph) depict the function   f(x)= -m(x-d)^1/5 i

step-by-step explanation:

we know that

m=slope

but in this function slope is -m that means slope is decreasing and it is decreasing by 1/5 points down the x-axis.

which is shown in graph four

a decreasing slope down x-axis by 1/5 points.

hence 4th graph is the right option for this.
