Answer:

ill just do the first page

Step-by-step explanation:

3(x-8)=5x+6

3x-24=5x+6

3x-5x-24=6

3x-5x=6+24

-2x=6+24

-2x=30

x=-15

4x+20+2(x-7)=0

4x+20+2x-14=0

6x+20-14=0

6x+6=0

6x=-6

x=-1

In a small town, electricity prices have been rising 2% each year since 2008. Which
mihalych1998 [28]
<h3>Answer: p = 0.12*(1.02)^t</h3>

Explanation:

The general exponential growth equation is

p = A*B^t

where t is the number of years that have gone by after 2008, A is the starting amount, B is the growth multiplier, and p is the price t years after 2008

We know that A = 0.12 is the starting price

The value of B is B = 1.02 which is in the form 1+r since 1.02 = 1 + 0.02 = 1+r

The r value is r = 0.02 and it is positive to represent growth. Keep in mind that 2% = 2/100 = 0.02

So we go from

p = A*B^t

to

p = 0.12*(1.02)^t

How do you find a rate of change
ddd [48]
Consider the line y = 2x + 1, shown at the right. Notice that this slope will be the same if the points (1,3) and (2, 5) are used for the calculations. For straight lines, the rate of change<span> (slope) is constant (always the same). For every one unit that is moved on the x-axis, two units are moved on the y-axis.hope this helped. </span>

The average hourly wage of computer programmers with 2 years of experience has been $21.80.Because of high demand for computer p
svp [43]

Answer:

d. H0: μ <= 21.80 Ha: μ > 21.80

Step-by-step explanation:

We set the null hypothesis as what is already given . We are already informed that the average wage is equal to  μ <= 21.80 against the claim that is required. It is required to test whether the average wage of the computer programmers is greater than μ > 21.80

So option d is the best answer.

Hypotheses testing is done  using an observation and a claim. The observation is set as a null hypothesis and claim is set as an alternative hypothesis. The null and alternative hypotheses must be chosen wisely to get the correct results.

The critical region is dependent on the claim set.

Which expression below gives the average rate of change of the function g(x) = -x2 - 4x on the interval 6 ≤ x ≤ 8 ?
Paha777 [63]

Answer: -18

<u>Explanation:</u>

Average rate of change is slope: \frac{y_{2}-y_{1}}{x_{2}-x_{1}}.  Need to find the y-coordinates:

g(x) = -x² - 4x

g(6) = -(6)² - 4(6)

      = -36 - 24

      = -60

⇒ (6, -60)

g(8) = -(8)² - 4(8)

      = -64 - 32

      = -96

⇒ (8, -96)

m = \frac{-96 - (-60)}{8 - 6}

   = \frac{-36}{2}

   = -18
