( x² - 1 ) / ( x² + 5 x + 4 ) < 0
x² + 5 x + 4 = x² + 4 x + x + 4 =  x ( x + 4 ) + ( x + 4 ) = ( x + 4 ) ( x + 1 )
Therefore:
( x - 1 ) ( x + 1 ) / ( x + 4 ) ( x + 1 ) < 0
( x -1 ) / ( x + 4 ) < 0
1.
x - 1 > 0  and x + 4 < 0
x  > 1  and  x < - 4       ( not possible ) 
2. 
x - 1 < 0 and x + 4 > 0
x < 1  and x > - 4 
Answer: x ∈ ( - 4, 1 ).

Helpppppp please and thank you guys!
Effectus [21]

Answer:

b = 3w; 54

Step-by-step explanation:

Since the student reads 3 books in one week, we know that one book is three times the amount of weeks, or b = 3w

We can plug in 18 for w to find how many books are read in 18 weeks

b = 3w

b = 3(18)

b = 54

So after 18 weeks she has read 54 books

How do i turn 24% into a fraction
PolarNik [594]
You can remove the % sign if you divide the number by 100:

\frac{24}{100}


This is because % is defined as 1/100, and the name (per-cent) actually meant this originally!
we can also simplify it: let's divide it by 4:

\frac{6}{25}

Given the linear equation, 2x +4= 6, find the rate, initial value, and specific value.
kap26 [50]

Answer: B. The rate is 2, the initial value is 4, and the specific value is 6.

Step-by-step explanation:

for a linear function y = a*x + b

Rate = coefficient that is multiplicating the variable. ( a in this case)

Initial value = value taken of y, when we have x = 0 (b in this case)

Specific value = value forced on y.

In this case, we have:

y = 6 = 2*x + 4

Then:

The coefficient multiplicating x is 2, so the rate is 2.

The constant term is 4, so the initial value is 4.

The value equal to y is 6, so the specific value is 6.

The correct option is B.
