Hi, here is the solution...

We need to find the value of f(-2).

The value of x = -2 comes under the second function f(x) = 4x, where -3≤x≤-1.

To find the value of f(-2), plug in x = -2 in f(x) = 4x

f(-2) = 4 (-2)

f(-2) = -8.

The answer is -8.


Thank you :)

zheka24 [161]

Answer:

15 to 27 (which is equal to 5:9)

Step-by-step explanation:

The ratio 15 to 12 indicates that there is a total of 27 people in the classroom (15+12).  So, if you want boys to total students, it's 15 to 27.  

You can divide each of these by 3 to simplify it and get 5:9.

PLZZZZ HELPPPPPP EXTREME FROWNIES IF U DONT ITS MATTTTHHHH
STALIN [3.7K]

Answer:

x=9 and angle B=40

Step-by-step explanation:

5x-5=3x+13

Subtract -3 on both sides of x

5x(-3)-5=3x(-3)=+13

2x-5=13

Add 5 to both sides

2x-5(+5)=13(+5)

2x=18

Divide by 2

x=9

Now that you know x=9, plug it into 3x+13

So, 3(9)+13= 27+13= 40

so ya thats my answer hopefully it helps

(btw both angle A and B are the same so thats why u put them equal)
