R+b=7 <br> 3.75r+2.75b=22.25

stiv31 [10]

Answer:

Step-by-step explanation:

hello :

r+b=7... (*)

3.75r+2.75b=22.25.... (**)

use (*) : r = 7 - b

put this value in (**) :

3.75(7 - b)+2.75b = 22.25

26.25 -375b +2.75b = 22.5

-375b +2.75b = 22.5 - 26.25

- b = -3.75

so : b = 3.75

but : r = 7 - b

r = 7 - 3.75

r = 3.25

What value must be defined for to remove the discontinuity of this function at ?

olchik [2.2K]

Answer:

Option D. 8

Step-by-step explanation:

we have

$f(x)=\frac{x^{2}-16 }{x-4}$

Remember that

$x^{2}-16 =(x+4)(x-4)$

substitute

$f(x)=\frac{(x+4)(x-4)}{x-4}$

Remove the discontinuity at x=4

Simplify

$f(x)=(x+4)$

so

Find the value of f(4)

For x=4

$f(4)=(4+4)=8$
