The answer is 12 because the x does not matter, due to the fact that there is no x in the equation. Hence forth, the answer is 12, because it is 7+5

How to find two consecutive integers for a product of 1295?
attashe74 [19]
Let the first integer be x; then the second is x+1.

The product of x and x+1 is x(x+1), and this product must equal 1295.

Thus, x^2 + x = 1295, or x^2 + x - 1295 = 0

Solve for x by completing the square:

          x^2 + x + (1/2)^2 - (1/2)^2 - 1295 = 0

           (x-1/2)^2 - 1/4 - 1295 = 0, or (x-1/2)^2 -5181/4 = 0, 
 
                Thus, x-1/2 = sqrt(5181/4), and so 

                           x      =  1/2+sqrt(5181/4) = 25.45

This could NOT be correct, since x and x+1 are CONSECUTIVE INTEGERS.

Krystal left the bookstore traveling 18 mph. Then, 3 hours later, Kori left traveling the same direction at 27 mph. How long unt
Eddi Din [679]

Answer:

Korl will catch up to Krystal in 2 hours.

Step-by-step explanation:

18x3=54 this shows how long Krystal has driven in 3 hours.

27x2=54 this shows that in 2 hours Korl will have driven 5 mph.

Now as you can see both quotient are 54 and the question is How long until Korl catches up to Krystal so it's 2 hours

Answer:

<em>Answer: Quadrant 4</em>

Step-by-step explanation:

<u>Graph of Functions </u>

Let's analyze the function  

\displaystyle y=\frac{x^2+3x}{x+1}

To better understand the following analysis, we'll factor y

\displaystyle y=\frac{x(x+3)}{x+1}

For y to have points in the first quadrant, at least one positive value of x must produce one positive value of y. It's evident that any x greater than 0 will do. For example, x=1 will make y to be positive in the numerator and in the denominator, so it's positive

For y to have points in the second quadrant, at least one negative value of x must produce one positive value of y. We need two of the factors that are negative. It can be seen that x=-2 will make y as positive, going through the second quadrant.

For the third quadrant, we have to find at least one value of x who produces a negative value of y. We only need to pick a value of x that makes one or all the factors be negative. For example, x=-4 produces a negative value of y, so it goes through the third quadrant

Finally, the fourth quadrant is never reached by any branch because no positive value of x can produce a negative value of y.

Answer: Quadrant 4
