castortr0y [4]2 years ago
5 0

4x = .125x + 5

3.875x = 5

x = 1.29032...

------------fraction:

4/1x = 1/8x + 5

32/8x = 1/8x + 5

31/8x = 5

Use cross multiplying

x =  40/31

X squared plus 5x plus 6 in a factor of binomials
Nadusha1986 [10]

Answer:

(x + 3)(x + 2)

Step-by-step explanation:

Given

x² + 5x + 6

Consider the factors of the constant term (+ 6) which sum to give the coefficient of the x- term (+ 5)

The factors are + 3 and + 2 , since

3 × 2 = 6 and 3 + 2 = 5 , thus

x² + 5x + 6 = (x + 3)(x + 2)

Algebra help - asymptotes
motikmotik

Find where the equation is undefined ( when the denominator is equal to 0.

Since they say x = 5, replace x in the equation see which ones equal o:

5-5 = 0


So we know the denominator has to be (x-5), this now narrows it down to the first two answers.


To find the horizontal asymptote, we need to look at an equation for a rational function: R(x) = ax^n / bx^m, where n is the degree of the numerator and m is the degree of the denominator.


In the equations given neither the numerator or denominators have an exponent ( neither are raised to a power)

so the degrees would be equal.

Since they are equal the horizontal asymptote is the y-intercept, which is given as -2.


This makes the first choice the correct answer.

Simplify the following polynomial expression​
Juli2301 [7.4K]

Distribute the negative sign

7x^2-3x-6

Combine like terms

-9x^2 + 7x^2 = -2x^2

9x - 3x = 6x

13 - 6 = 7

-2x^2 +6x + 7

<u>Answer</u>

-2x^2 +6x + 7
