Solve the system for a and b:
9 = ab^2
-72=ab^5

a = , b = - 2

Step-by-step explanation:

Given the 2 equations

9 = ab² → (1)

- 72 = a → (2)

Divide (2) by (1)

=

- 8 = b³ ( take the cube root of both sides )

= b , that is

b = - 2

Substitute b = - 2 into (1) and solve for a

9 = a(- 2)² = 4a ( divide both sides by 4 )

= a

last one.

step-by-step explanation:

last one.

generally speaking, the others follow some sort of pattern that correlates to either linear (looks like a straight line) or sinusoidal (looks like an s).

the last one is just a random cloud of points that doesn't correlate to any particular known order.
