Answer:

Try solving 6(n-5)-2.

Step-by-step explanation:

I believe this can be set up as 6(n-5)-2. The difference of a number and five can be represented by n-5. If this needs to be multiplied by 6 (hence 6 times), it would become 6(n-5). Two less than that is represented by -2. Thus, two less than six times the difference of a number and five is 6(n-5) -2, which, when n=9 is plugged in, looks like 6(9-5) -2. Follow PEMDAS from there.

Answer:

$y=-3,250t+25,000$

Step-by-step explanation:

we know that

The linear equation in slope intercept form is equal to

$y=mx+b$

where

m is the slope of unit rate of the linear equation

b is the y-intercept or initial value of the linear equation

Let

t ----> the number of years since 2011

y --->the car's value

In this problem the year 2011 represent t=0

the year 2015, represent t=4 years (2015-2011)

we have the ordered pairs

(0,25,000) ----> represent the y-intercept

(4,12,000)

<em>Find the slope m</em>

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{t2-t1}$

substitute the values

$m=\frac{12,000-25,000}{4-0}$

$m=\frac{-13,000}{4}$

$m=-\$3,250\ per\ year$ ---> is negative because is a decreasing function

we have

$b=\$25,000$ ----> value of y when the value of x is equal to zero (initial value)

substitute the given values

$y=-3,250t+25,000$

1. What is the solution set for -4x - 10 ≤ 2 ?

tresset_1 [31]

Answer:

x≥−3

Step-by-step explanation:

−4x−10≤2

Step 1: Add 10 to both sides.

−4x−10+10≤2+10

−4x≤12

Step 2: Divide both sides by -4.

−4x−4≤12

−4

x≥−3

Residents of three counties were polled to find the percentage of residents who are Republican or Democrat.

Savatey [412]

Using it's concept, the relative frequencies are given as follows:

Republican residents of County 1: 37.9%.

Democratic residents of County 1: 62.1%.

Total Republican residents: 58.9%.

Total Democratic residents: 41.1%.

<h3>What is a relative frequency?</h3>

A relative frequency is given by the<u> number of desired outcomes divided by the number of total outcomes</u>.

In County 1, we have that there are 6,520 residents, out of which 4,050 are Democratic and 2,470 are Republican, hence the relative frequencies are given as follows:

Republican residents of County 1: 2470/6520 = 37.9%.

Democratic residents of County 1: 4050/6520 = 62.1%.

In total, there are 24,505 residents, out of which 10,075 are Democratic and 14,430 are Republican, hence the relative frequencies are given as follows:

Total Republican residents: 14430/24505 = 58.9%.

Total Democratic residents: 10075/24505 = 41.1%.
