This cannot be simplified into the ratio of two integers,  Square roots that cannot be simplified are irrational  

B. -√81

- 9

-9/1  which is the ratio of two integers so it is rational

c. 5/4

This is the ratio of two integers so it is rational

d. 9.12

Answer:

Slope form of line  y = 9

Step-by-step explanation:

m= 3

The y-intercept of the line that passes through the given point  (0,9) is

 9 = 3(0) + b

  b= 9

The equation of the line that passes through the given point  (0,9) is

y =mx +b

 y = 0 +9

at the zoom,the ratio of monkeys to gorrillas is 5:2 if there were 20 monkeys how many gorrilas would there be?
Umnica [9.8K]

8 gorrilas

Explanation:

The ratio of monkeys to gorrila = 5:2

This means there are 5 monkeys for every 2 gorrilas

when there are 20 monkeys,

let the number of gorrilas = x

5 monkeys = 2 gorrilas

20 monkeys = x

cross multiply:

5(x) = 20(2)

5x = 40

divide both sides by 5:

5x/5 = 40/5

x = 8

Hence, if there were 20 monkeys, we would have 8 gorrilas.

-4y>2x+4 What is the slope of this
vovikov84 [41]
Answer: -1/2

Explanation: -4y > 2x + 4; isolate the y by dividing both sides by -4 and get:
y = -2/4x + 4; simplify
y = -1/2x + 4

In y = mx + b; m is the slope

In this case, -1/2 is the slope
