The sum of two numbers is 70. One number is 10 more the twice the other number.

GalinKa [24]

Answer:

20 and 50

Step-by-step explanation:

x + y = 70

y = 2x + 10

Use the substitution method:

y = 70 - x

y = 2x + 10

70 - x = 2x + 10

3x = 60

x = 20

x + y = 70

20 + y = 70

y = 50

x = 20

y = 50

Which of the following is equal to the rational expression when x -2 or -6?

kykrilka [37]

The given expression is

$f(x) = \frac{3(x+2}{(x+2)(x+6)}$

And since we have x+2 common in numerator and denominator, there is a hole at x+2=0, that is at x=-2

And a function is undefined when denominator is zero. And at x=-6, denominator become zero.

So, at x=-6, the function is undefined, or there is a vertical asymptote at x=-6 and hole at x=-2 .
