Write and graph an inequality for the given solution set {n∣n≥−2}
Answers
Answer:
Explanation:
An inequality is used to represent unequal expressions or numbers. An inequality with the solution set [tex]n \ge -2[/tex] is: [tex]2n - 6 \ge -10[/tex]
Given that:
[tex]n \ge -2[/tex] --- the solution
To generate an inequality with the above solution, we do the following:
Subtract 3 from both sides of the inequality
[tex]n - 3 \ge -2 - 3[/tex]
[tex]n - 3 \ge -5[/tex]
Several operations can be carried out. The most important thing to note is that, whatever operation is done on the right-hand side of the inequality must be done on the left-hand side.
We can also multiply both sides by 2
[tex]2 \times (n - 3 )\ge -5 \times 2[/tex]
[tex]2n - 6 \ge -10[/tex]
Hence, an inequality with the solution set [tex]n \ge -2[/tex] is:
[tex]2n - 6 \ge -10[/tex]

Step-by-step explanation:
Devon earns $35 per hour for a regular 40-hour work week. Sometimes, he works over 40 hours a week and earns "double time" for the extra hours worked. (That means that his hourly rate for the additional hours over 40 hours per week is double his normal hourly rate.) If Devon works 48 hours in one week, how much would he earn that week?
Answers
Answer:
1960
Step-by-step explanation:
40 times 35 = 1400
8 times 2 times 35 = 560
1400+560=1,960$
When Devon works for 48 hours in one week the total amount he earned that week is equal to $1960.
To calculate Devon's earnings for the week when he works 48 hours,
Consider his regular pay for the first 40 hours and then the "double time" pay for the additional 8 hours.
Regular pay for 40 hours: Devon earns $35 per hour for a regular 40-hour work week.
Regular pay = $35/hour × 40 hours = $1400
Overtime pay for the additional 8 hours: Devon works 48 hours in total, so he works 8 hours over the regular 40-hour work week.
For these 8 hours, he earns "double time," which means his hourly rate is doubled.
Double time rate = 2 × $35 = $70/hour
Overtime pay
= Double time rate × Number of overtime hours
= $70/hour × 8 hours
= $560
Total earnings for the week: To find the total amount earned in the week, add the regular pay and the overtime pay.
Total earnings
= Regular pay + Overtime pay
= $1400 + $560
= $1960
Therefore, if Devon works 48 hours in one week, he would earn $1960 that week.

Kelsey wants to buy some new shirts at her favorite store. Each shirt costs $10 and she also wants to get a pair of shoes for $25.write an inequality. That she could use to figure out how many shirts she can buy if the most she can spend is $55 and solve
Answers
Answer:
10x + 25 less than or equal to (the sign) $55
Step-by-step explanation:
Answer:
The inequality is 10x + 25 [tex]\geq[/tex] 55
Step-by-step explanation:
This would be the possible inequality, because it says that "EACH" shirt costs 10$ meaning that Kelsey may buy multiple, which is why you would want to put 10x (for every shirt she buys they each cost 10 dollars) and PLUS she wants a pair of sneakers, so add 25 $
She has only 55$ to spend, so here MAXIMUM amount she can spend is 55$ which means, she can only buy whatever she wants for 55$ or lower.
4+7a=12+8a
with steps pls
Answers
Answer:a=-8
Step-by-step explanation:
4+7a=12+8a
So first you want to have the variables on the same side
4+7a-7a=12+8a-7a
This is how you got the 7a to the right side. Then you subtract 8a-7a So the equation becomes
4=12+a
Now there are two ways of doing this.
1. 4-12=12-12+a
You moved the 12 to the left side so you have the same variable on one side
4-12=-8
So then a=-8
Or
2. 4-4=12-4+a
0=8+a
then you would have to subtract 8 to keep 'a' by itself
-8=8-8+a
simplify it
-8=a
same thing
step 1: subtract 7a from both sides.
now you have 4=12+a
step 2. subtract 12 from both sides.
now you have -8=a
the answer is a=-8

a projectile is thrown upwards from an initial height of 1584 feet so that it's distance above the ground after t seconds is modeled by the given function.
h(t)=-16t^2+480t+1584.
what is the maximum height it will reach?
Answers
Answer:
5184 ftStep-by-step explanation:
Given
A quadratic function
h(t)= -16t^2+480t+1584.Its maximum is its vertex
Vertex formula for ax^2 + bx + c is
x = -b/2aApplying this to our function
t = -480/2(-16) = 15Maximum height is reached after 15 seconds and is
h(15) = -16*15^2 + 480*15 + 1584 = 5184 ftA store has all board games on sale for 25% off the
regular price. A checker set has a sale price of $12. It is then moved to a clearance table where every item is discounted 40% off its regular price. What is the
clearance price of the checker set?
Answers
Answer:
$7.20
Step-by-step explanation:
We'll need to find out 40% of 12 then subtract that amount because we're still paying 60% of the original price.
Change the percent to a decimal: 0.4
Multiply the sale price and the decimal
12 · 0.4 = 4.8
Subtract 40% of the price from 12
12 - 4.8 = 7.2
The clearance price of the checker set is $7.20
Answer:
If both the board games discount and the clearance discount affect the item, this means it is 65% off. 65% of 12 is 7.8, therefore we subtract that amount from 12 and get 4.2, or $4.20.

A map shows a section of Interstate 94 that forms a straight line. A family plans to drive 72 miles on Interstate 94 from St Paul, MN to Elk Mound, WI. They drive for 20 miles, and then decide they will stop halfway through their trip to eat. How much farther do they need to drive before they stop for dinner?
Answers
Answer:
16 miles
Step-by-step explanation:
Given that:
Total distance of the trip = 72 miles
They have decided to stop half way their trip i.e. they will stop at a distance [tex]\frac{72}{2} =36[/tex] miles from the starting point.
Also, given that they have already traveled for 20 miles.
To find:
How much farther do they need to drive before they stop for dinner?
Solution:
Distance already covered = 20 miles
Distance to be covered before stopping for dinner = 36 miles
Distance to be covered more = Total distance to be covered before stopping - Distance already covered
[tex]\Rightarrow 36-20 =\bold{16\ miles}[/tex]
A new underground rollercoaster is being installed. The height of the rollercoaster in feet throughout the underground section is modeled by the equation h(d) = 0.15d2 – 1.5d, where d represents horizontal distance in feet. What's the height of the rollercoaster 6 feet horizontally through the underground section?
Answers
Answer:
3.6 feet
Step-by-step explanation:
The height of the rollercoaster in feet throughout the underground section is modeled by the equation :
[tex]h(d) = 0.15d^2 - 1.5d[/tex] ....(1)
We need to find the height of the rollercoaster 6 feet horizontally through the underground section.
Put d = 6 feet in equation (1) as follows :
[tex]h(6) = 0.15(6)^2 - 1.5(6)\\\\h=-3.6\ \text{feet}[/tex]
or
h = 3.6 feet
So, the height of the rollercoaster 6 feet horizontal through the underground section is 3.6 feet.
