Answer:

1. 6.13

2. 0.57

Step-by-step explanation:

1. 7 x 4 = 28

28 / 8 = 3.5

3.5 x 7 = 24.5 / 4 = 6.13

s = 6.13

2. 2 x 3 = 6

6 / 7 = 0.85

0.85 x 2 = 1.71

1.71 / 3 = 0.57

s = 0.57

F(x)=2x and g(x)=2x+3,what is the value of f(g(-8))
jok3333 [9.3K]

Answer:

f(g(-8)) = -26

Step-by-step explanation:

Given:

f(x)=2x and g(x)=2x+3

Required:

f(g(-8))=?

Solution:

First we will find g(-8)

g(x) = 2x+3

g(-8)= 2(-8)+3

      = -16 + 3

      = -13.

so, g(-8) = -13

Now, for calculation f(g(-8)) we can put the value of g(-8) i.e, -13

so, f(x) = 2x

    f(-13)  = 2(-13)

             = -26

so, f(-13) = -26

and f(g(-8)) = -26

Solve the system using elimination<br> 3x+y=27<br> -3x+4y=-42
padilas [110]

Hello :)

3x+y=27

-3x+4y= -42

+____________

(3x -3x) + (y+4y) = (27-42)

0 + 5y = -15

y = -3

Put "-3" for "y" in the system:

3x + y =27

3x -3=27

3x = 30

x = 10

Answer = x:10 y: -3

Have a nice day :)
