What is an equation of the line that passes through the points (-6, -4)(−6,−4) and (3, 8)(3,8)?
Answer:
y = 4/3x + 4
Step-by-step explanation:
-4 - 8 / -6 - 3
-12 / -9
4/3 is slope
y = 4/3 x + b so we need to find b
Put one of the points in for y and x.
-4 = 4/3 (-6) + b
-4 = -8 + b
4 = b
y = 4/3x + 4
How to find a and b in the equation below.
3(a+b)=28
Answer:
a equals and b equals 7
Step-by-step explanation
divide both side by 3 getting a+b=(28/3)
subtract b from both sides getting a=(28/3)-b
to solve for b its the same way so b=(28/3)-a
you can then substitute
-3(-3x-7)=48 please show work
Answer:
x = 3Step-by-step explanation:
-3(-3x - 7) = 48=> 9x + 21 = 48=> 9x = 48 - 21=> 9x = 27=> x = 3Conclusion:
Therefore, the answer is 'x = 3'.

Answer:
−3(−3x−7)=48
Divide both sides by −3.
−3x−7= 48
Divide 48 by −3 to get −16.
−3x−7=−16
Add 7 to both sides.
−3x=−16+7
Add −16 and 7 to get −9.
−3x=−9
Divide both sides by −3.
x= −3 −9
Divide −9 by −3 to get 3.

If f(x) = -3x - 5 and g(x) = 4x - 2, find (f - g)(x).
A. (f- g)(x) = -7x - 3
B. (f- g)(x) = x - 3
C. (f - g)(x) = -7x + 3
D. (f- g)(x) = x - 7
Answer:
A. (f-g)(x) = -7x -3
Step-by-step explanation:
(f -g)(x) = f(x) -g(x) = (-3x -5) -(4x -2)
= -3x -5 -4x +2
= -3x -4x -5 +2
(f -g)(x) = -7x -3

Find the fourth degree polynomial function with zeros 6,-6,6i
Answer:
See below
Step-by-step explanation:
6 is a solution to x-6=0, -6 is a solution to x+6=0, and 6i is a solution to x^2+36=0. So, we can do (x-6)(x+6)(x^2+36) to get (x^2-36)(x^2+36) which gets us x^4-1296. Therefore, the fourth degree polynomial with zeroes 6, -6, 6i is x^4-1296
if the tank length is 24 inch and width is 12 inch then how much litre of water is in it?
Answer:
Step-by-step explanation:
How to Estimate Aquarium Water Volume
You can estimate the amount of water that a tank can hold by using the volume formula for the shape of your tank. The process is similar to calculating tank volume for other tanks, but the formulas are a bit different for different aquarium shapes.
You’ll need a different formula to find the volume for rectangular, bow front, cylindrical, and other aquarium shapes.
Tank Volume Formulas
See the volume formulas for various aquarium fish tank styles below.
Rectangular Tank Formula
tank volume = l × w × h
l = tank length
w = tank width
h = tank height
The cost in dollars for a group to attend a play is represented by 72p + 250. where p is the number of people attending what is the cost for 36 people.
A. 286
B. 358
C. 2,342
D. 2,842
Based on the equation that is given, the total cost for the group to attend a play will be 2842.
From the information given, the cost in dollars for a group to attend a play is represented by 72p + 250.
Therefore, when the number of people are 36, the cost will be:
= 72p + 250
= 72(36) + 250
= 2592 + 250
= 2842

hope I helped! I need to write more words so I can send this
Answer:
The answer is A
Step-by-step explanation:
|6x + 3| = 27
Use the definition of absolute value6x + 3 = 27
6x + 3 = -27
Subtract three from both sides of the equation.6x = 24
6x = -30
Divide both sides by 6.x = 4
x = -5

In 2013, a State Library received a three-year grant to add 69,678 books to their
collection. During a used book sale, the library sold 430 books. If the collection
now is five times more than the original number of books, how many books did
the library hold before it received the grant?
The number of books the library holds before it received the grant is 17,312 books
Let the original number of books in the library be x
If the State Library received a three-year grant to add 69,678 books to their collection, the total number of books will be x + 69,678If during a used book sale, the library sold 430 books, the remaining books will be (x+69,678) - 430 = x + 69,248If the collection now is five times more than the original number of books, then;
x + 69,248 = 5x
5x - x = 69,248
4x = 69,248
x = 69,248 /4
x = 17,312
Hence the number of books the library holds before it received the grant is 17,312 books

For which of the following geometric series can the infinite sum be determined? a1 = –0.25, r = –3 a1 = 0.75, r = 4 a1 = 3, r = 2 a1 = 5, r = –0.5
So, the infinite sum can be determined in the geometric series a₁ = 5, r = -0.5.
For a geometric series the infinite sum is given by s = a/(1 - r) where a = first term, r = common ratio and |r| < 1.
For each of the geometic series given below, we need to determine if |r| < 1.
For a₁ = -0.25, r = - 3, |r| = |-3| = 3 > 1
For a₁ = 0.75, r = 4, |r| = |4| = 4 > 1
For a₁ = 3, r = 2, |r| = |2| = 2 > 1
For a₁ = 5, r = -0.5, |r| = |-0.5| = 0.5 < 1
Since we require |r| < 1 to find the infinite sum and |r| in the last geometric series |r| = 0.5 < 1, the infinite sum can be found in the geometric series a₁ = 5, r = -0.5..
So, the infinite sum can be determined in the geometric series a₁ = 5, r = -0.5.
