( \frac{f}{g} )(4) =  \frac{f(4)}{g(4)}  =  \frac{ {4}^{2} + 2 \times 4 - 3 }{ {4}^{2}  - 9}  =  \\  =  \frac{16 + 8 - 3}{16 - 9}  =  \frac{21}{7}

(f + g)(4) = f(4) + g(4) = 21 + 7 = 28

Well he probably likes you and if you like him tell him, but make sure he isn’t playing you and you are ok with dating first. If you don’t like him and he likes you let him down nicely cause you don’t wanna be rude. All the signs are there, so do what ever pleases you.

I need help ASAP PLEASEEEEEEEEEEEEEEEEEE
Oksanka [162]

Answer:

97,99,101,103

Step-by-step explanation:

Let x = first odd integer

x+2 = 2nd odd integer

x+4 = 3rd odd integer

x+6 = 4th odd integer

Sum of 4 odd integers is 400

x+ (x+2) + (x+4)+(x+6) = 400

Combine like terms

4x +12 = 400

Subtract 12 from each side

4x+12-12 = 400-12

4x = 388

Divide by 4 on each side

4x/4 = 388/4

x=97

The first integer is 97

The 2nd is 97+2 =99

The third ix 97+4 = 101

The 4th is 97+6 = 103

How do you do this equation: 9|5x+8|=54
Sergio [31]

Answer (2 answers):

x = -2/5,  x = -14/5

Step-by-step explanation:

First step is to try and get the absolute value by itself on one side and everything else that's not inside the absolute value on the other side.

9|5x+8|=54

|5x+8| = 54/9

|5x+8| = 6

Remember how absolute values turn everything positive? For example

|-4|=4, but |4|=4 as well. So we must do the same to our problem by splitting up the absolute equation into two parts.

|5x+8| = 6     and     |-(5x+8)| = 6

now solve the first equation.

(Just remove the absolute value sign and solve it normally)

5x+8 = 6

5x = -2

x = -2/5

Now solve the other equation

-(5x+8) = 6

-5x - 8 = 6

-5x = 14

x = -14/5
