Brian received 45 trading cards from his mother and 25 trading cards from his uncle to start a collection.
Each week, Brian uses his allowance to buy a new pack of 15 trading cards to add to his collection.
Write an equation in slope-intercept form to represent the situation. Use x for the independent variable and y for the dependent variable. Identify what both variables represent.
Answer:
The representation of Brian's situation in slope intercept form is:
y= 15x +70
Step-by-step explanation:
Let x be the number of weeks Brian started his collection.
y be the number of cards Brian has at present.
y= 45+25+ 15 x
or, y= 15 x +70
which is in the form of,
y= mx +c (slope intercept form)
where,
m= slope
x= x- intercept
c= constant.
please help I will appreciate it
Answer:
A) 4 [ x-value of the intercept of the 2 lines]

The change in the average price of a gallon
of milk from 2011 to 2013 is shown in the
table below.
At the end of 2010, the price of a gallon of
milk was $3.47.
What was the price, in dollars, of a gallon of milk at the end of 2013?
Answer:
Price at the end of 2011 :
$3.47 - 0.57 = $2.90
Price at the end of 2012 :
$2.90 + $0.25 = $3.15
Price at the end of 2013 :
$3.15 - $0.08 = $3.07
So, at the end of 2013, the price of a gallon of milk was $3.07 .

What is the solution
Please help
Answer:
Step-by-step explanation:
1.)
3x=3
x=1
2+y=0
y=-2
solution: (1,-2)
2.)
6y = -36
y = -6
-4x+12 = -12
-4x=-24
x = 6
solution: (6,-6)
Answer:
Top: x=1, y= -2
Bottom: x= 6, y= -6
Step-by-step explanation:
Top:
Isolate x for y: 2(3+y) + y = 0
Simplify: 6+3y=0
Isolate y for 6+3y=0: y = -2
For x= 3 + y: x = 1
Bottom:
Isolate x for : -4x - 2y= -12: x= [tex]\frac{-6 + y}{2}[/tex]
Simplify: 6y+ 12 = -24
Isolate y for 6y+ 12 = -24: y = -6
For x= [tex]-\frac{-6 -6 }{2} = 6[/tex] : x = 6

A community swimming pool has a deep end and a shallow end. The volume of water in the deep end can be represented by (2x2+12x+10) ft3 and the volume of the water in the shallow end can be represented by (4x2−100)ft3.
Write the equivalent expression ("simplified") that represents the total volume of the water in the pool in ft3.
Answer:
The total volume of water in the pool = ( 6x^3 + 12x^2 - 90x ) ft^3
Step-by-step explanation:
The volume of water in the deep end = (2x^3 + 12x2 + 10x) ft^3
The volume of water in the shallow = (4x^3 -100x) ft^3
The total volume of water in the pool = (2x^3 + 12x2 + 10x) + 4x^3 -100x)
= ( 6x^3 + 12x^2 - 90x ) ft^3
Help asap pls. The mean of a math test took by 50 students is 85% Two students got a 10% on the test. If those outliers were removed, what would the new mean be? Pls don't answer for points. And also DONT ANSWER TO ASK A QUESTION COMMENT IT. it takes away a chance for people who actually know the answer to answer
Answer:
okay I'm not 100% sure but I have a good idea (it's okay if u remove me it's just an educated guess)
89%
Step-by-step explanation:
if there were 100 students that would mean 1 student represented 1% of the results. so if there were 50 students 1 student would represent 2% of the results. so if two students were removed then that would mean the result would improve by a total of 4% which would get you 89%

Answer:
We can see from the table that 1 km is exactly half way between 2 and 3 laps. So it will take 2.5 laps to run 1 km.
Since it takes Angel 2 minutes to run 1 lap, she will take
2.5 laps1 km⋅2 minutes1 lap=5 minutes1 km.
So it takes Angel 5 minutes to run 1 km.
Since it takes Jayden 5 minutes to runs 3 laps, she runs 1 lap in 53 minutes. Thus, it takes Jayden
2.5 laps1 km⋅5 minutes3 laps=52⋅53 minutes/km=256 minutes/km=416 minutes/km.
So it takes Jayden 416 minutes to run 1 km.
Step-by-step explanation:
i actually dont know what the answer-answer is but i think this will help alot.
Answer:
Step-by-step explanation:
Distance traveled in 2 minutes by Angel = 2/5 kilo meter
Distance traveled in 1 minute by Angel = [tex]\frac{2}{5}[/tex] ÷ 2
[tex]=\frac{2}{5}*\frac{1}{2}[/tex]
= 1/5 kilometer
Find the perimeter and the area of the polygon with the given vertices.
A (12,2), B (12,13), C (15,13), D (15,2)
The perimeter is __ units.
The area is __ square units.
Answer:
Step-by-step explanation:
As points A and B have same x-coordinate, length of AB will be given by the difference of y-coordinate
AB = 13 - 2 = 11 units
As points C and D have same x-coordinate, length of CD will be given by the difference of y-coordinate
CD = 13 - 2 = 11 units
As points B and C have same y-coordinate, length of BC will be given by the difference of x-coordinate
BC = 15 - 12 = 3 units
As points A and D have same y-coordinate, length of AD will be given by the difference of x-coordinate
AD = 15- 12 = 3 units
AB = CD = 11 units
BC = AD = 3 units
So,ABCD is a rectangle
Area = 11 * 3 = 33 square units
Perimeter = 11+11+3+3 = 28 units
Answer:
Solution :-At first
Length of AB = 13 - 2 = 11 cm
Length of CD = 13 - 2 = 11 cm
Length of BC = 15 - 12 = 3 cm
Length of AD = 15 - 12 = 3 cm
Now
Perimeter = 11 + 11 + 3 + 3
Perimeter = 22 + 6
Perimeter = 28
Area = 11 × 33 = 33 cm

Answer:
53.12ft
Step-by-step explanation:
Area of triangle:
The formula to find the area of a triangle is 1/2bh
- We plug in the values given.
1/2 x 8 x 7
Which is 28ft.
Area of semicircle:
The formula to find the area of a semicircle is 1/2[tex]\pi[/tex][tex]r^{2}[/tex]
- We plug in the values given
1/2 x [tex]\pi[/tex] x [tex]4^{2}[/tex]
1/2 x 16[tex]\pi[/tex]
8[tex]\pi[/tex] or 8 x 3.14 = 25.12
In order to get the total area of the whole shape we need to add the areas of those two, which will be 25.12 + 28 = 53.12

Answer:
as the drive's age increses the insurences goes down
Step-by-step explanation:
please help im lost i dont understand this objective
Answer:
Explained Below
Step-by-step explanation:
You'll want to start off by knowing the formulas for the area and perimeter of triangles:
Area Formula - A= 1/2 bh (1/2 x base x height)
Perimeter Formula - P = a + b + c (sides added together)
So, we will plug in the numbers.
Triangle 1: A = 1/2 bh So, A = 1/2 8 x 10, which means half of 8 or 10 multiplied by the number that you did not half. (For instance: If you half 8, that means you multiply 4 and 10.) Now, you should have A = 40 either way (4 x 10 = 40 and 8 x 5 = 40).
P = a + b + c. So, you will add 8, 6, and 10. This is 14.
Triangle 2: A = 1/2 bh. But, this triangle requires you to cut in half. Doing this, that cuts your base as well. It will no longer be 30, by 15. For the left side of triangle 2, it will be A = 1/2 15 x 12, which you half either 15 or 12, where 12 is easier. Now it should be A = 15 x 6, which is 90. The right side of the triangle will be A = 1/2 15 (12) as well, which is also 90. In the end, you will add it together, which is 180.
P = a + b + c. So, you will add 15, 23, and 12 first. Then, add 15, 20, and 12. You should have 50 and 47, which you will add that together as well.
Triangle 3: I will keep working on this one, as I am a little unsure :/
Triangle 4: You will do the same steps for this triangle like you did on #2. Though the numbers you plug on are different. A = 1/2 bh - A = 1/2 10 x 14. (This is for the left side) You will have to half either the base or the height's number. So, it will be A= 5 x 14 or A=10 x 7. Then, you will multiply and find your answer (70). (This is for the right side) A = 1/2 10 x 14. Due to the numbers being the same, it can be shown that the area will also be 70. You then add 70 and 70 together.
P = a + b + c. You will add 10, 14, and 15 for the left side and 10, 14, and 17 for the right side. Once you add them separately, add the answers together (10+14+15 =39 and 10+14+17 = 41. 39 + 41 = 80.
Triangle 5: A=1/2 bh. A = 1/2 12 x 16. You will half either 12 or 16 (It does not matter). Then you should have A = 6 x 16 or A = 12 x 8. Either way, your answer is 96.
P = a + b + c. You will add 12, 16, and 18. This results in 46.
Hope this helps! I will continue to figure out Triangle 3
