Solve for x. I need help with this problem. <br><br>​
Advocard [28]

Answer:

x = 9

Step-by-step explanation:

Rule: the two interior angles F and E when added, equal <FGH.

so

6x + 16 + 60 = 13x + 13  Combine the terms on the left.

6x + 76 = 13x + 13          Subtract 13 from both sides.

6x + 76-13 = 13x             Combine

6x + 63 = 13x                  Subtract 6x from both sides.

63 = 7x                            Divide by 7

63/7 = x

x = 9

Find the vertical and horizontal asympotote for (×-2) (×+3)/ (2×+2)
nekit [7.7K]

\bf \cfrac{(x-2)(x+3)}{2x+2}\implies \cfrac{x^2+x-6}{2x+2}~~ \begin{array}{llll} \leftarrow \textit{2nd degree polynomial}\\ \leftarrow \textit{1st degree polynomial} \end{array} \\\\[-0.35em] ~\dotfill\\\\ \stackrel{\textit{vertical asymptote}}{2x+2=0}\implies 2x=-2\implies x=-\cfrac{2}{2}\implies x=-1


when the degree of the numerator is greater than the denominator's, then it has no horizontal asymptotes.


quick note:

when the degree of the numerator is 1 higher than the degree of the denominator, then it has an slant-asymptote, so this one has a slant-asymptote.

A county government says that a safe level of chlorine in a hot tub is within 1.75 ppm of 3.25 ppm.
Schach [20]

Answer:

Part A : <u>|x-2.5| ≤ 0.75  , x ∈ [1.75,3.5]</u>

Part B : yes, the lifeguard should add more chlorine.

Step-by-step explanation:

Part A:

Let  C is the variation of the level of chlorine in a hot tub.

Level of chlorine in a hot tub is within 1.75 ppm of 3.25 ppm.

To find absolute value inequality, need to find the standard level of chlorine 1.75 + C or 3.25 - C

1.75 + C = 3.25 - C

2C = 5

C = 2.5

So, the standard level would be 2.5 ppm,

If x represents the present level of chlorine,

Then it would be lie within 1.75 ppm of 3.25 ppm.

1.75 ≤ x ≤ 3.25

Subtract 2.5 from all sides

1.75 - 2.5 ≤ x -2.5 ≤ 3.25 - 2.5

-0.75 ≤ (x-2.5) ≤ 0.75

which is equivalent to the following absolute value inequality.

<u>|x-2.5| ≤ 0.75</u>

<u>And the solve of the inequality : x ∈ [1.75,3.5]</u>

Part B:  If x = 1.0 ppm,

∴ |1.0-2.5| = 1.5 which is not less than equal to 0.75.

Another explanation:

the minimum safe level of chlorine in a hot tub is 1.75 ppm

Since 1 < 1.75

Therefore, lifeguard should add more chlorine.
