Kx=3 I'm pretty sure

Answer:

1/3k

Step-by-step explanation:

30kx -6kx=8

We can operate the two terms in left because they are similar

24kx = 8

We divide by 8 both sides

3kx = 1

Finally, we divide by 3k both sides

x = \frac{1}{3k}

If a line has slope​ a, what is the slope of its reflection across the line y​=x?
aleksandrvk [35]

Check the picture below.

notice the reflected gray line on the red one over the y=x line, the slope of either line across the y=x line is simply the other's upside-down.

\stackrel{\textit{slope of line "a"}}{a\implies \cfrac{a}{1}}\hspace{5em}\stackrel{\textit{slope of its reflection}}{\cfrac{1}{a}}

The crime rate of a certain city is increasing by exactly 6% each year. If there were 550
kap26 [50]

Using an exponential function, it is found that the approximate number of crimes in the year of 2016 was of 2502.

<h3>What is an exponential function?</h3>

An increasing exponential function is modeled by:

A(t) = A(0)(1 + r)^t

In which:

  • A(0) is the initial value.
  • r is the growth rate, as a decimal.

In this problem, there were 550 crimes in the initial year observed, and the growth rate is of 6%, hence the parameters are A(0) = 550, r = 0.06, and the equation is given by:

A(t) = A(0)(1 + r)^t

A(t) = 550(1 + 0.06)^t

A(t) = 550(1.06)^t

2016 is 26 years after 1990, hence:

A(26) = 550(1.06)^{26} \approx 2502

The approximate number of crimes in the year of 2016 was of 2502.
