Choose the missing step in the given solution to the inequality −6x − 10 > 14 + 2x. (1 point)
−6x − 10 > 14 + 2x
_______________
-8x>24
x 14
B.) -8x -10 >14
C.)−4x − 10 < 14
D.) −8x − 10 < 14
Answer:
- 8x > 24
Step-by-step explanation:
Given
- 6x - 10 > 14 + 2x ( subtract 2x from both sides )
- 8x - 10 > 14 ( add 14 to both sides )
- 8x > 24 ← required missing step
Divide both sides by - 8, reversing the symbol as a result of dividing by a negative quantity.
x < - 3 ← is the solution

Write an equation in slope intercept form that passes through the point (-4,2) and is perpendicular to y=2x+2.
Answer:
Step-by-step explanation
Perpendicular lines have slopes that are negative reciprocals of one another.
so, in this case, the given slope is 2.
The negative reciprocal of that would be -1/2.
so far, our equation looks like: y=-1/2x+b
now, take the point given to us, (-4,2) and plug it into the y and x values.
2= -1/2(-4) +b
2= b+2
b=0
Our y intercept is zero, so our final answer will be:
[tex]y=-\frac{1}{2} x[/tex]
Calculate the perimeter of the semi-circle shown below. Use 3.14 to approximate n.
========================================================
Explanation:
A full circle of radius r has the circumference of
C = 2*pi*r
A semicircle will have us divide this value in half
2pi*r turns into pi*r
The curved distance along the top is roughly pi*r = pi*5 = 3.14*5 = 15.7 cm.
Add this onto the straight line distance along the bottom to arrive at 15.7+10 = 25.7 cm

Have a wonderful day!
From the definition of the range, we understood that the given statement is false.
The given statement is "The range is calculated by adding the highest and lowest scores in a data set and then dividing by the number of scores in the dataset".
We need to state whether the given statement is true or false.
What is the range?The range formula is mostly used in statistics to determine the range given in a particular data set. The formula helps in determining the centre of the set by finding the difference between the lowest and the highest number. In distribution, the large range means higher variability whereas the small range means low variability. The range formula includes the other aspects of statistics such as mean, median, and mode. Hence, the formula to calculate the range is:
R = Highest Value (H) - Lowest Value (L).
Therefore, from the definition of the range, we understood that the given statement is false.

Answer as a compound inequality: [tex]-4 \le y < 2[/tex]
Answer in interval notation: [-4, 2)
=============================================
Explanation:
The range is the set of all possible y outputs of a function. When dealing with a graph like this, we just look at the highest and lowest points to determine which y values are possible.
The lowest point occurs when y = -4. We include this value. So far we have [tex]y \ge -4[/tex] which is the same as [tex]-4 \le y[/tex]
The upper ceiling for the y value is y = 2. We can't actually reach this value because of the open hole at (-3,2). So we say that [tex]y < 2[/tex]
Combine [tex]-4 \le y[/tex] and [tex]y < 2[/tex] to get the compound inequality [tex]-4 \le y < 2[/tex]
This says y is between -4 and 2, including -4 but excluding 2.
To convert this to interval notation, we write [-4, 2) where the square bracket says to include the endpoint and the curved parenthesis says to exclude the endpoint.

Given the following exponential function, identify whether the change represents
growth or decay, and determine the percentage rate of increase or decrease.
Y= 30(1.003)^x
For the given exponential function, the change represents a growth and the percentage rate is 0.3%.
Exponential FunctionThe formula for the exponential function is:
[tex]y(t)=y(0)*(1+R)^t[/tex], where:
y(t)= final value
yo=initial value
R=rate
t= time
When 1+R > 1, the equation represents growth, while 1+R < 1 the equation represents decay.
The question gives: [tex]y=30*(1.003)^x[/tex].
When you compare [tex]y=30*(1.003)^x[/tex]with [tex]y(t)=y(0)*(1+R)^t[/tex], it is possible to see:
1. 1+R=1.003, so >1 . Therefore, the change represents growth.
2. 1+R=1.003 , therefore,
1.003=1+R
R=1.003-1
R=0.003
then,
%R=0.003*100=0.3%

Eric made $289 for 17 hours of work.
At the same rate, how many hours would he have to work to make $ 119?
Answer:
7 hours
Step-by-step explanation:
You would divide 289 by 17. You get 17. Then you would divide 119 by 17 and you get 7
Answer:
7 Hours of work to earn $119
Step-by-step explanation:
You would divide $289 by 17 hours to find your hourly wage. You would find the hourly wage to be $17 an hour. Then you would take $119 and divide it by $17, and you'll find the number 7, this is your hours of work you have to work to earn $119.

Monica has $20. she needs to buy a gallon of milk that costs $2.50. she also wants to buy yogurt, which costs $1.20 a cup. which inequality can you use to find the number of cups of yogurt monica can buy? 1.20x 2.5 greater-than-or-equal-to 20 1.20x 2.5 less-than-or-equal-to 20 1.20x 2.5 < 20 1.20x 2.5 > 20
The inequality which is used to find the number of cups of yogurt Monica can buy is,
[tex]1.20x+2.5\leq20[/tex]
What is the inequality equation?Inequality equation is the equation in which the two expressions are compared with greater than, less than or other inequality signs.
Monica needs to buy a gallon of milk that costs $2.50. She also wants to buy yogurt, which costs $1.20 a cup. Let suppose the number of cups of yogurt bought by Monica is x.
As she has only $20. Thus, the inequality expression which can be used for this condition is,
[tex]1.20x+2.5\leq20[/tex]
Solve the above equation and find the value of x,
[tex]1.20x\leq20-2.5\\1.20x\leq17.5[/tex]
Divide both side with 1.20,
[tex]x\leq\dfrac{17.5}{1.20}\\x\leq14.58\overline3[/tex]
Hence, the number of cups she can Monica is 14.
Thus, the inequality which is used to find the number of cups of yogurt Monica can buy is,
[tex]1.20x+2.5\leq20[/tex]

Gianna works in a department store selling clothing. She makes a guaranteed salary of $500 per week, but is paid a commision on top of her base salary equal to 15% of her total sales for the week. How much would Gianna make in a week in which she made $975 in sales? How much would Gianna make in a week if she made xx dollars in sales?
Earnings when selling $975:
Earnings when selling $x:
Answer:
$646.25 is her earnings when selling $975.
Her earnings when selling $x is 500 + 0.15x.
Step-by-step explanation:
You know that her guaranteed salary is $500, and she also gets a commission that is 15% of her sales. So, the expression is
500 + 0.15x
Where x is total sales. When you are given $975 as her total sales, plug it in for x:
500 + 0.15(975)
500 + 146.25
$646.25 is her earnings when selling $975.
Her earnings when selling $x is 500 + 0.15x.
Carlos took seven years to pay off his loan by making identical quarterly payments. the loan had a principal of $22,375 and 5.49% interest, compounded quarterly. carlos paid a total of $28,821.67. how much did carlos pay in service charges? round all dollar values to the nearest cent. a. $1,721.31 b. $4,725.36 c. $1,670.98 d. $6,446.67
The Carlos pay in service charges is $1721.3
We have given that the Carlos took seven years to pay off his loan by making identical quarterly payments.
The loan had a principal of $22,375 and 5.49% interest, compounded quarterly.
P=22375 and interest rate =5.49%
Carlos paid a total of $28,821.67.
We have to find how much did Carlos pay in service charges
First we find the monthly payment of the loan
What is the formula of monthly payment?The formula for monthly payment is,
[tex]M=\frac{amount}{discount}[/tex]
Discount factor
[tex]P=\frac{1-(1+i)^{-n}}{i} \\[/tex]
Where, Amount = $22,375 and r=0.0549 and compounded quarterly therefore n=4
[tex]i=r/n=0.0599/4[/tex]
i=0.0137
Time =7 years
[tex]n=4\times 7=28[/tex]
Now put all the values in above formula we get
[tex]P=\frac{1-(1+0.01372)^{-28}}{0.01372}\\\\P=\frac{1-(1+0.1372)^{-28}}{0.01372}\\\\P=\frac{1-0.6827}{0.01372}\\\\P=\frac{0.3172}{0.01372}\\\\P=23.11[/tex]
Monthly payment,
Use the value in the formula of monthly payment
[tex]M=\frac{22375}{23.1177}[/tex]
[tex]M=967.871[/tex]
The payment he has for for 7 years compounded quarterly that is for 28
Therefore the payment,
[tex]Payment= 967.871 \times 28 = $27100.39[/tex]
[tex]Service charges = Total payment - payment[/tex]
[tex]= $28,821.67 - $27100.39[/tex]
[tex]= $1721.27[/tex]
Therefore, Carlos pay in service charges is $1721.3
