Answer:

Answer: D

Step-by-step explanation:

Using the equation plot in the coordinates of the points to see if they fit the equation.

5x-3y < 30

A) 5(-3) -3(5) < 30

-15 -15 < 30

-30 < 30 This is true

B) 5(0) -3(0) < 30

0 - 0 < 30

0< 30 This is true

C) 5(-5) - 3(3) < 30

-25 - 9 < 30

-34 < 30 This is also true

D) 5(3) - 3(-5) < 30

15 + 15 < 30

30 < 30 This is not true because 30 is not greater that 30

Can 39/121 be simplified and if so what is it??

Answers

Hi there!

Unfortunately, the beautiful fraction you've given us is simplified enough, and it cannot go any lower than what it is. So basically, you're left with $(39)/(121)$

Hope this helps!

Message me if you need anything else! I'd be happy to help! :D

Write an equation of the parabola in intercept form that passes through (−18, 72) with x-intercepts of −16 and −2.

Answers

y = a(x + 16)(x + 2)

72 = a(-18 + 16)(-18 + 2)

72 = a(-2)(-16)

72 = a(32)

$(72)/(32) = a$

$(9)/(4) = a$

Answer: y = $(9)/(4)$ (x + 16)(x + 2)

A fishery is an area with the specific purpose of controlling fish populationsfor commercial or recreational fishing. Population dynamics describe how afish population changs over time. The population is changed by birth, death,and migration of fish.
