Answer:

Step-by-step explanation:

1) x + 7 = 12

Add the additive inverse of 7  = -7 to both sides

x + 7 - 7 = 12 - 7

x + 0 = 5

x = 5

2) 7a = -28

Divide both sides by 7

7a/7 = -28/7

a = -4

3)\frac{y}{8}= -3\\\\

Multiply both sides by 8

\frac{y}8}*8=-3*8\\\\y=-24

Find the value of k such that lim--&gt;4 (x^2+x-k)/(x-4) exists
7nadin3 [17]

Answer:

k=20

Step-by-step explanation:

when x approaches 4, the denominator x-4 approaches 0

if the denominator is 0, it means that this is invalid

if the function is a number over 0 when x=4, it represents a vertical asymptote, which means no limit

so the only way possible to let there be a limit is to let the function be 0/0 when we plug in x=4

so x^2 + x - k = 0 when x = 4

4^2 + 4 - k = 0 ==> 20 - k = 0 ==> k = 20
