Answer:

We conclude that the value of k represented as a decimal rounded to the nearest tenth is:  k = 16.8

Step-by-step explanation:

Given the expression

\frac{5}{7}=\frac{12}{k}

We need to determine the value of k, represented as a decimal rounded to the nearest tenth.

Let us solve the expression

\frac{5}{7}=\frac{12}{k}

Apply cross-function multiply:   if \frac{a}{b}=\frac{c}{d}  then a\cdot \:d=b\cdot \:c

5k=7\cdot \:12

5k=84          ∵ 7 · 12= 84

Divide both sides by 5

\frac{5k}{5}=\frac{84}{5}

Simplify

k=\frac{84}{5}

k = 16.8    (Rounded to the nearest 0.1 or  the Tenths Place)

Therefore, we conclude that the value of k represented as a decimal rounded to the nearest tenth is:   k = 16.8

What is the horizontal asymptote of the rational function f(x) = 3x / (2x - 1)?
-BARSIC- [3]

Answer:

Step-by-step explain

Find the horizontal asymptote for f(x)=(3x^2-1)/(2x-1) :

A rational function will have a horizontal asymptote of y=0 if the degree of the numerator is less than the degree of the denominator. It will have a horizontal asymptote of y=a_n/b_n if the degree of the numerator is the same as the degree of the denominator (where a_n,b_n are the leading coefficients of the numerator and denominator respectively when both are in standard form.)

If a rational function has a numerator of greater degree than the denominator, there will be no horizontal asymptote. However, if the degrees are 1 apart, there will be an oblique (slant) asymptote.

For the given function, there is no horizontal asymptote.

We can find the slant asymptote by using long division:

(3x^2-1)/(2x-1)=(2x-1)(3/2x+3/4-(1/4)/(2x-1))

The slant asymptote is y=3/2x+3/4

System by elimination <br><br>2x - y = -3 <br>-2x - 8y = 12​
topjm [15]

Answer:

x= -2 y= -1

Step-by-step explanation:

stack the 2 equations on top of each other and add them together

the 2x and -2x cancel out and you are left with -9y=9

this gives you y= -1

you plug the y value into one of the equations:

2x - (-1) = -3

2x+1 = -3

2x= -4

x= -2
