Answer:
The equation to express this situation is y = 15x + 50.
Step-by-step explanation:
Initially, the temperature of a pot of water is 50⁰, i.e. at after x = 0 minutes the temperature was, y = 50⁰.
And the temperature rises 15⁰ per minute.
So, after x₁ = 5 minutes, the temperature was, y₁ = 125⁰.
And similarly after x₂ = 10 minutes, the temperature was, y₂ = 200⁰.
Compute the equation to express this situation as follows:
[tex](y-y_{1})=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}\cdot (x-x_{1})\\\\(y-125)=\frac{200-125}{10-5}\times (x-5)\\\\y-125=15x-75\\\\y=15x-50[/tex]
Thus, the equation to express this situation is y = 15x + 50.

Annie wants to make several plates of apples and apricots, so that each plate has the same number of apples and the same number of apricots. At most, how many plates can she make, if she is going to use 8 apples and 20 apricots.
At most, 8 apples and apricots can be arranged at ___ plates, so that each plate contains ___ and ___ apricots.
Please help! I need help filling in the blanks.
Answer:
At most, 8 apples and apricots can be arranged at 4 plates, so that each plate contains 2 apples and 5 apricots.
Step-by-step explanation:
they are asking for the GREATEST amount of plates, but there are less apples than apricots so we must find the GCF, which is 4. then you divide the amount of apples by 4 as well as the amount of apricots by 4.
hope this helped :D
please help me!!! :)
I would assume that the angle of f equals 50°... sincesince the triangles are similar that means that the angles are most likely equal to each other. since the big triangle you can do it 90 + 40 which equals 130 then 180, since that is the total degrees in a triangle, minus 130 equals 50 this means 50 ° is the angle of c. keep in mind angle c equals angle f.

(Urgent please help!!!) Maria earned $5,250; $4,800; $3,990 and $5,120 from her home business during the last four months. What was her average monthly income during this period?
i need help please help
Answer:
The answer is 46 degrees.
Step-by-step explanation:
To find angle RPQ, subtract 108 from 180 because a straight line equals 180 degrees.
108 - 180 = 72
A triangles angles add up to 180. We have two of them. To find the third angle, subtract the two angles from 180.
180 - 72 - 62 = 46.

11. Alicia and three friends are making a video
to post online. The three friends all made
video segments of equal length, and Alicia's
video segment is less than 5 minutes long.
Let s represent the length of each of the
friend's segments. Write an inequality to
represent the length l of the full video.
Al> 3s + 5 © e> 3s + 5
Be<3s + 5 D &< 35 +5
Answer:
L < 3s + 5
Step-by-step explanation:
Given that:
Video length of all 3 friend are equal
Let the length of the video made by each friend = s
Length of video of all 3 friends = 3s
Alicia's video segment is less than 5 minutes long
Hence the length L of the full video :
L = (Length of video of all 3 friends + Alicia's video segment)
Since Alicia's < 5
Hence full video length :
L < 3s + 5

what is 4y = 3(x - 22) written in standard form
please help quick
Answer:
-3x+4y=- 66
Step-by-step explanation:
The first step is to multiply 3 by x and - 22. Should be 3x and -66
Now plug in the numbers.
4y = 3x - 66
Secondly, bring the 3x over to the left.
You get
-3x + 4y = -66

[tex]p(m) = 2m+8[/tex]
The function p above models the total price p( m ), in dollars, of streaming m movies per month from an online movie subscription service. The subscription service charges an $8 monthly fee plus an additional fee per movie streamed. Which of the following is the best interpretation of p( 10) in this context?
A) The total price for streaming 1 movie in a month is $10.
B) The total price for streaming 2 movies in a month is $10.
C) When 10 movies are streamed in a month, the total price that month is $18.
D) When 10 movies are streamed in a month; the total price that month is $28.
9514 1404 393
Answer:
D) When 10 movies are streamed in a month; the total price that month is $28.
Step-by-step explanation:
Using the function definition, put 10 where you find m, then evaluate:
p(10) = 2(10) +8 = 20 +8
p(10) = 28
The function definition tells you this (28) is the price of streaming 10 movies in a month.

If 14-2x1 = 20, x could equal which of the following?
Answer:
x=-3
Step-by-step explanation:
Answer:
-3
Step-by-step explanation:
Find the center and radius of the equation of the circle
a). x2 + y2 – 8x +6y + 9 = 0
Compare the given equation with the general equation of a circle
Given equation: x² + y² - 8x +6y +9 = 0
Equation of a circle: x² + y² + 2gx + 2fy + c = 0
2g= -8; g = -8÷2= -4
2f = 6; f = 6÷2 = 3
c= 9
Solving for radius of the circle...
r =√g² + f² - c
g= -4, g² = ±16
f = 3, f² = 9
Substituting, we have
r = √16 + 9 - 9
r = √25-9
r=√16
r = 4
Therefore, the centre and radius of the circle is 9 and 4 respectively.
Hope this helped!

3 < y ⩽ 7 where y is an integer Write down all the possible values of y
add 4 i guess. i dont really know
Answer: 4, 5, 6, 7
Step-by-step explanation:
Let’s break this apart into 3 < y and y <= 7.
We can rewrite 3 < y as y > 3, and we also have that y <= 7.
This is equivalent to the verbal expression y is greater than 3 and less than or equal to 7.
We can then conclude that y must be between 4 (since that is the first number greater than 3) and 7 (since y includes 7).
Therefore, y can be 4, 5, 6, or 7!

There were 400 sweets in a pack. The principal of a school bought 25 such packs of sweets for 2000 children o Children's Day. If each child was given 7 sweets, how many more packs of sweets were needed?
Answer:
10 more packs
Step-by-step explanation:
400 sweets bought 25 such packs = 400*25=10000
2000 each one gets 7 = 2000*7=14000
14000-10000=4000
4000/400 is 10.
So 10 more packs.
Hit the crown :D
Answer:
Step-by-step explanation:
400 sweets in a pack * 25 packs = 10,000 sweets
2000 kids * 7 sweets = 14,000
We need 4,000 more sweets. That would be 10 packs more since there are 400 sweets in a pack.

Find the value of x. (Hint: The sum of the angles in
a triangle is 180 degrees.)
The value of x is degrees.
Answer:
look below
Step-by-step explanation:
Subtract the sum of the two angles from 180 degrees. The sum of all the angles of a triangle always equals 180 degrees. Write down the difference you found when subtracting the sum of the two angles from 180 degrees. This is the value of X.
