Find the equation (in terms of x) of the line through the points (-2,3) and (4,-9)
y =
Answer:
y =5
Step-by-step explanation:
m=
−9−7
5−5
=
−16
0
=0
y=mx+b
5=(0)(7)+b
b=5
therefore y = 5
Answer: y = -2x - 1
Step-by-step explanation:
We can calculate the slope from the two given points. Slope is the change in y per the change in x, sometimes called the rise (y) over the run (x)
Rise is (-9 -3) = -12
Run is (4 - (-2)) = 6
Slope = Rise/Run = -12/6 = -2
The line is y = -2x + b
Find b by using either of the two known points (solutions). I'll choose (-2,3) [because I like smaller numbers]
y = -2x + b
3 = -2*(-2) + b
b = -1 [That was only slightly easier than -9 = -2*(4) + b; b = -1]
The equation is y = -2x - 1
y=5+2x when x=4, what does
/
y equal
Answer:
y = 13
Step-by-step explanation:
Y = 5 + 2x but when x = 4 you replace any X variables with 4
So the equation now is 5 + 2(4) = 5 + 8 = 13
y = 13

Karen's music library contains 18 fewer playlists than Clarann's music library. The total number of playlists on both music libraries is 40. Find the number of playlists on each person's music library.
Answer:
let Karen's music library be represented by K
let Clarann's music library be represented by C
C = K +18
C +K =40
put C = K +18 into (C +K =40)
K + 18 +K =40
2K +18 = 40
collect like terms
2K =40 -18
2K =22
divide both sides by 2
K =11
since C = K+18
C= 11 +18
C =29
Karen's music library contains 11 playlists while Clarann's music library contains 29 playlists

Flights 204 and 317 are both approaching Hartsfield Atlanta International Airport from directions directly opposite one another and at an altitude of 2.5 miles. The pilot on flight 204 reports an angle of depression of 17 degrees 47 minutes to the tower, and the pilot on flight 317 reports an angle of depression of 12 degrees 39 minutes to the tower. Calculate the distance between the planes.
Answer:
19.26 milesStep-by-step explanation:
Refer to attached picture. Not to scale.
The picture explains all the given parameters.
We need to find the distance d, which is the sum of x and y.
First convert minutes to degrees:
47 min = 47/90 deg = 0.52 deg39 min = 39/90 deg = 0.43 degFind x:
x/2.5 = cot (17.52°) ⇒ x = 2.5*3.1677 ≈ 7.92 miFind y:
y/25 = cot (12.43°) ⇒ y = 2.5*4.5369 ≈ 11.34 miThe distance between the planes:
7.92 + 11.34 = 19.26 miBRIANLIST ANSWER pls help i meant to put science
Answer:
I'd say Yev's description is best because it's the most specific to what it actually is in terms of science, while everyone else's descriptions are more like examples of different types and stages of energy, and where it could be found.

Answer:
Out of State = 54
Step-by-step explanation:
Out of State
2/9 = x/243
= 54
Answer:
54
Step-by-step explanation:
7 in-state to 2 out-of-state
The sum of 7 and 2 is 9.
For every 9 students, 2 are out of state.
This is the proportion:
2 out-of-state is to 9 total as x out-of-state is to 243 total
2/9 = x/243
9x = 2 * 243
x = 54
Answer: 54
5. Find the measure of the missing angle.
40°
50°
Step-by-step explanation:
40° + 90° + ? = 180°
130° + ? = 180°
? = 180° - 130°
? = 50°
Answer: 50 degrees
Step-by-step explanation: The interior angles add up to 180.
1. 40 + 90 + ? = 180
130 + ? = 180
-130 - 130
? = 50

A ride sharing company offers two options: riding in small cars that can carry up to 3 passengers each, or riding in large vans that can carry up to 6 passengers each. A group of 27 people is going to use the ride sharing service to take a trip. The trip in a small car costs $10 and the trip in a large van costs $15. The group ends up spending $80 total. An equation that represents one of the constraints is 3x+6y=a. What is the value of a?
Answer:
a = 27
Step-by-step explanation:
3x + 6y = a
From the given information, 3 and 6 are the numbers of passengers that cars and vans can take. That means x and y must be the numbers of cars and vans, and a is the total number of passengers.
a = 27

What is the value of x in the equation 3x/4=24
Answer:
X= 32
Step-by-step explanation:
Answer:
X = 32
Step-by-step explanation:
If you do 24 x 4 you will get 96.
From there you have to divide 3 by 96, since 3 times x has to equal to 96. Since 24 x 4 is 96 and you need to divide 3x by 4.
After you do 96/3 you will get 32. Thus the answer being 32.
Hope this helps!
