for < or > line is - - - - - - - -
for ≤ or ≥ line is _________
for < or ≤ shaded below the line
for > or ≥ shaded above the line
Therefore your answer is the third graph.
Answer:
Option C. is the correct option.
Step-by-step explanation:
The given inequality is 2y > x - 2
1). As we know on a graph > (greater than) sign reflects the shaded part above the line
and < (less than) tells about the shaded region below the line.
2). If there is a sign of equality ≥ or ≤ then the line is denoted by a solid line in the graph.
When signs are in the form of > or < only then line will be in the dotted form.
By these rules we can easily say shaded area above the dotted line represents the solution area of the inequality 2y > x - 2.
Therefore, option C is the answer.

DaMontre is at basketball practice, where he takes 30 shots a minute. He also took an extra 70 shots before practice. If DaMontre took 1,870 shots, how long did he practice for?
Answers
DaMontre practiced for 60 minutes after taking a total of 1,870 shots, with an initial 70 shots before practice and 30 shots per minute during practice.
Explanation:The question asks how long DaMontre practiced basketball if he took a total of 1,870 shots, with a pre-practice session of 70 shots, and during practice, he takes 30 shots a minute.
Step-by-step solution:
First, subtract the extra shots DaMontre took before practice from the total number of shots to find out how many shots were taken during practice. So, 1,870 - 70 = 1,800 shots during practice.
Next, to find out how long he practiced for, divide the number of shots taken during practice by the rate at which he takes shots per minute. Therefore, 1,800 shots divided by 30 shots/minute = 60 minutes.Thus, DaMontre practiced for 60 minutes, which is the answer to the question.
the graph of a quadratic function has a vertex ar (3,-6). One point of the graph is (7,10). What is another point on the graph?
Answers
Answer:
y + 6 = (x -3)^2
Step-by-step explanation:
Let's use the general form of the vertex equation of a quadratic: y - k = a(x - h)^2.
Subst. 10 for y, 7 for x, -6 for k and 3 for h. Then, 10 + 6 = a(7 - 3)^2, or
16 = a(4)^2, or 16 = a(16). Thus, a = 1, and the equation of this particular parabola is:
y + 6 = (x -3)^2
Given a quadratic function with a vertex at (3,-6) and a point (7,10), by substituting the values into the equation, we find that another point on the graph is (4,-5).
The vertex form of a quadratic function is [tex]\(y = a(x - h)^2 + k\)[/tex], where (h, k) is the vertex of the parabola. In this case, the vertex is (3, -6), so the equation is [tex]\(y = a(x - 3)^2 - 6\).[/tex]
You're also given a point on the graph, which is (7, 10). You can use this point to find the value of a.
Substitute the point's coordinates into the equation and solve for a:
[tex]\(10 = a(7 - 3)^2 - 6\)[/tex]
[tex]\(10 = a(4^2) - 6\)[/tex]
10 = 16a - 6
Now, isolate a:
16a = 10 + 6
16a = 16
a = 1
Now that you know a = 1, you can use this information to find another point on the graph. Simply plug in a different value for x into the equation. Let's choose x = 4 for example:
[tex]\(y = 1(4 - 3)^2 - 6\)[/tex]
y = 1(1) - 6
y = 1 - 6
y = -5
So, another point on the graph is (4, -5).

35 and a 1/2 weeks
36 weeks to have the full amount needed
Answer:
36th weeks
Step-by-step explanation:
Kelsey has saved $35 to buy a video game worth $390.
She plans to save additional $10 per week.
Let w represents number of week.
Let s represents total saving in w weeks.
Addition saving per week = $10
In w weeks saving = 10w
Previous saving amount = $35
Total saving in w week, s = 35 + 10w
Expression which represents total saving in w weeks
s = 35 + 10w
Now find number of weeks to save $390
So, put s=390 and solve for w
35 + 10w = 390
10w = 390 - 35
w = 355÷10
w = 35.5
Hence, Kelsey will save $390 in 36th weeks.

hi, I am a sub for Glenridge and I need the answer to the question as soon as possible please here is the question Carl is boarding a plane. He has 2 checked bags of equal weight and a backpack that weights 4 kg. The total weight of Carl's baggage is 35 kg.
Write an equation that illustrates the problem and can be used to determine the weight, w, of each of Carl's checked bags.
Answers
The equation to determine the weight of each of Carl's checked bags is 2w + 4 = 35. After solving, we find that each checked bag weighs 15.5 kg.
To solve the problem regarding Carl's baggage weight, we set up an equation. Carl has two checked bags of equal weight, let's call the weight of each bag w kilograms. He also has a backpack weighing 4 kg. According to the problem, the total weight of all his baggage is 35 kg. We can represent this situation with the following equation:
2w + 4 = 35
This equation adds the weight of the two checked bags (2w since there are two of them and they are equal in weight) and the 4 kg backpack to get the total weight of 35 kg. To find the weight of each checked bag, we can simply subtract the weight of the backpack from the total weight and then divide by two:
Subtract the weight of the backpack from the total weight: 35 - 4 = 31 kgDivide the remaining weight by two to find the weight of each checked bag: 31 / 2 = 15.5 kgTherefore, the weight of each of Carl's checked bags is 15.5 kg.

Angle (<) E and <F are vertical angles. If m<E = 17x+1 and m<F =20x-14, find m<F.
Answers
The vertical angles theorem states that vertical angles are congruent to each other. Since angles E and F are vertical angles, this means you can make them equal to each other in an equation.
m∠E = m∠F
17x + 1 = 20x - 14
Subtract 20x from both sides.
-3x + 1 = -14
Subtract 1 from both sides.
-3x = -15
Divide both sides by -3.
x = 5
Substitute 5 for x in m∠F (20x - 14).
20(5) - 14 = 86
m∠F = 86°

The floor of a room is being covered with tile. An area of 3/4 of the length and 3/5 of the width is covered. Find the fraction of the floor that has been covered.
Answers
To determine the fraction of the floor covered, we multiply the fraction of the length covered (3/4) by the fraction of the width covered (3/5), resulting in a covered area of 9/20 of the floor space.
To find the fraction of the floor that has been covered by tile, we need to multiply the fraction of the length covered by the fraction of the width covered. If an area of 3/4 of the length and 3/5 of the width is covered, then we perform the multiplication: (3/4) x (3/5) = 9/20.
This means that the fraction of the floor covered with tile is 9/20. This fraction represents the percentage of the entire floor that is tiled, which in this case indicates that less than half of the room is covered because 9/20 is less than 1/2.

7.Subtract 3x − 4 from 5x + 7.
8.Subtract −4x + 1 from x − 2.
Answers
1) Given m represent the total number of miles Hannah walked.
Let us assume Hannah walked x miles each day.
So total number of miles Hannah walked in 5 days is m=5x.
2)Given Jimmy brought 2 books per day and Peter brought 4 books per day.
If d is the number of days the book drive, total number of books they brought
=total number books brought by Jimmy+ total number of books brought by Peter
= 2d+4d = 6d
3) Given that c represent cost of the clothes.
Then 30% discount = 0.3c
Hence cost of the clothes = c-0.3c = 0.7c
4) Given c represent the cost of their meal before tipping.
And tip is 15% of the cost.
Hence tip = 0.15c
Hence total bill = c+0.15c=1.15c
5) Given that Tommy had 40$ in his pocket.
And pair of pants cost 37$ with 10% sales tax.
Hence cost of pants including sales tax = 37+37*0.1 = 40.1$ >40$
Hence Tommy cannot afford the pants with 40$ in his pocket.

5. ∠4 = 110°
6. ∠11 = 70°
7. ∠5 = 65°
8. ∠14 = 115°
Step-by-step explanation:
Given that, two parallel lines and two transversal lines.
also given that, ∠1 = 115° & ∠12 = 110°
We know that, straight angle = 180°
∠1 + ∠2 = 180°
∠2 = 180 - 115
∠2 = 65°
∠2 & ∠5 are vertical angles. So, they are same
∠2 = ∠5
∠5 = 65°
Similarly, ∠1 = ∠6 (vertical angles)
∠6 = 110°
Now given that, ∠12 = 110°
∠11 + ∠12 = 180°
∠11 = 180 -110
∠11 = 70°
∠11 & ∠16 are vertical angles.
∠11 = 16
∠16 = 70°
∠12 = ∠15 (vertical angle)
∠15 = 110°
∠4 & 12 are Corresponding Angles
∠12 = ∠4
∠4 = 110°
∠3 = 180 - ∠4 = 180 - 110
∠3 = 70°
∠7 = ∠4 (vertical angle)
∠7 = 110°
∠3 = ∠8 (vertical angle)
∠8 = 70°
∠1 = ∠9 (Corresponding Angles )
∠9 = 115°
∠10 = ∠2 (Corresponding Angles )
∠10 = 65°
∠13 = ∠10 (vertical angle)
∠13 = 65°
∠14 = ∠9 (vertical angle)
∠14 = 115°

Since we have given that
Amount spent at her community college = $2300
Amount spent of that on books = $276
We need to find the percent of last semester's college costs was spent on books is given by
[tex]\dfrac{276}{2300}\times 100\\\\=\dfrac{27600}{23}\\\\=12\%[/tex]
Hence, there is 12% of last semester's college costs was spent on books.
The student spent 12% of last semester's college costs on books.
How to solve the percentageTo find the percentage of last semester's college costs that was spent on books, you can use the following formula:
Percentage = (Part / Whole) * 100
In this case:
The "Part" is the amount spent on books, which is $276.
The "Whole" is the total college cost for last semester, which is $2300.
Percentage = ($276 / $2300) * 100
Percentage = (0.12) * 100
Percentage = 12%
