1. Mara has $640 in her bank account. If she withdraws $30 every month, in how many months will she have $370 remaining in her account
2. Make up an equation that has no solution and explain what that means. (Hint: It has to be a real explanation, not just "it doesn't work").
Answer:
610, 580, 550, 520, 490, 460, 430, 400, 370 It takes 9 months
Step-by-step explanation:
2: 1.50+x=π This problem is impossible. This is because Pi is a number that goes for infinitiy so there is no answer for x. This also means ∞ can also be an answer.
Answer:
1. 9
2.
Step-by-step explanation:
1. Mara has $640 in her bank account, she withdraws $30 each month. We don't know how many months will she withdraw until 370$. Let's write an expression first:
640 - 30x = 370
Now, subtract both sides by 640 to get -270:
-30x = -270
Last, divide both side by -30:
-30x = 270
x = 9
Now, we know she withdraws $30 for 9 months.
2. 2 + 4(3 - 2) = x
This tells us that we do not know the answer until we solve it.
2 + 4(3 - 2) = x
2 + 12 - 8 = x
6 = x
f(x)=4x-3, g(x)=10-x
Work out gf(x)?
Step-by-step explanation:
Given
f(x) = 4x - 3
g(x) = 10 - x
So Now
gf(x) = g( 4x - 3)
= 10 - 4x + 3
= 13 - 4x
Hope it will help :)❤

(x - 12y = -4
( x - 9y = 7
9514 1404 393
Answer:
(x, y) = (40, 11/3)
Step-by-step explanation:
The variable x can be eliminated by subtracting the first equation from the second.
(x -9y) -(x -12y) = (7) -(-4)
3y = 11 . . . . . . .simpify
y = 11/3 . . . . . .divide by 3
x -9(11/3) = 7 . . . . substitute for y in the second equation
x = 40 . . . . . . . add 33
The solution is (x, y) = (40, 11/3).

find the y-coordinate of the y-intercept of the polynomial function defined below f(x)=2x(x^2+3)
Answer:
y-intercept is (0,0). Mark brainliest?
Answer:
Step-by-step explanation:
2x([tex]x^{2}[/tex] + 3)
when x = 0 then we have a y intercept
2[tex]x^{3}[/tex] +6x
so b/c both terms have an x in them
we know the only time this function hits the y intercept is when y is zero
got it?
answer y = 0
A bird can lay either white or brown eggs. Three white eggs
and
two brown eggs have a mass of 13 grams, while five white eggs
and four brown eggs have a mass of 24 grams. Find the mass
of a brown egg and of a white egg.
Answer:
Mass of brown egg = 3.5 grams
Mass of white egg = 2 grams
Step-by-step explanation:
Let
Mass of brown eggs = x
Mass of white eggs = y
3y + 2x = 13 (1)
5y + 4x = 24 (2)
Multiply (1) by 5 and (2) by 3 to eliminate y
15y + 10x = 65 (3)
15y + 12x = 72 (4)
Subtract (3) from (4)
12x - 10x = 72 - 65
2x = 7
x = 7/2
x = 3.5
Substitute x = 3.5 into (1)
3y + 2x = 13 (1)
3y + 2(3.5) = 13
3y + 7 = 13
3y = 13 - 7
3y = 6
y = 6/3
y = 2
Mass of brown egg = 3.5 grams
Mass of white egg = 2 grams

csc^-1 4.25 to degrees
9514 1404 393
Answer:
13.609°
Step-by-step explanation:
The csc^-1 function is the arccosecant function. It gives the angle whose cosecant is given. If we let A represent that angle, your statement is ...
A = csc^-1(4.25)
It is used to solve the relation ...
4.25 = csc(A)
__
Some calculators can give you the value directly (see attached). Most cannot. In any event, you need to make sure the angle mode for the calculator is set to degrees.
When your calculator does not have the csc^-1 function, you can make use of the trig identity ...
csc(x) = 1/sin(x)
In the above equation, this becomes ...
4.25 = 1/sin(A)
sin(A) = 1/4.25 . . . . . solve for sin(A)
All scientific and graphing calculators will have the inverse sine (arcsine) function.
A = sin^-1(1/4.25)
A ≈ 13.609° . . . . . . . calculator mode in Degrees
_____
Additional comment
For inverse functions, especially inverse trig functions, I find it useful to read them as ...
csc^-1(x) ⇒ "the angle whose cosecant is x"
sin^-1(x) ⇒ "the angle whose sine is x"
This reminds me that the value it gives is an angle (degrees or radians), and the argument it takes is a pure number (one with no units).

Answer:
Disney The Jungle Book (the first one): Mowgli (played by Neel Sethi) is a young boy that was raised by a family of wolves. One day he has to leave his home when the fearsome tiger, named Shere Khan (voiced by Idris Elba) unleashes a powerful roar. With aid from a panther (voiced by Ben Kingsley) and a care-free bear (voiced by Bill Murray), Mowgli meets a ton of new jungle animals. A few of which include a slithery python and a friendly ape. Along his way, Mowgli learns valuable lessons about life in this movie full of fun and adventure.
The Jungle Book (the second one): This is a classic Walt Disney animation that is based on Rudyard Kipling's book. Mowgli is a young, abandoned child who was raised by wolves. One day his peaceful life is threatened by the evil tiger, named Shere Khan (voiced by George Sanders). Mowgli must leave his wolf family behind in order to return to the "man village." Throughout his quest he is not alone, aided by a panther named Bagheera, and later on, a carefree bear named Balloo, he traverses the jungle's many perils.

3) In the diagram shown, circles with centers at points A and B intersect at points Cand D. Segments AC, BC, AD and BD have been drawn to form quadrilateral ACBD. Circle A has a radius of length 5 cm and circle B has a radius of 3 cm. What is the perimeter of ACBD? Justify. (3 points)
Answer:
16 cm
Step-by-step explanation:
Whatever the positions of A and B changed, AC always = AD = 5 cm
and BC = BD = 3 cm
perimeter of ACBD = 2*5 + 2*3 = 16 cm

Help I need to do that I don’t even know what it is I’ll
Give brianliest
Answer:
Step-by-step explanation:
1. f(x) = 5x² + 3x - 1
a. f(0) = 5·0² + 3·0 - 1 = -1
b. f(-1) = 5(-1)² + 3(-1) - 1 = 1
Do the same for f(2), f(√2), f(a+2), and f(a).
Then do the same thing for the next function.
2. f(x) = x/(1-x)
a. f(0) = 0/(1-0) = 0
Do the same for f(-1), f(2), f(√2), f(a+2), and f(a).

Derek earns $ 4800 in 3 months. what is his annual income
Answer: Annual Income Is $192000
Step-by-step explanation:
firstly know one month income we divide by 48000 by 3
= 16000
we know one month income 16000
than we for know annual income we multiply by 12
16000×12 =192000
annual income is $192000
If two lines have the same y intercept and the same slope will they intercept at exactly one point?
True or false or partly true
Answer:
False because the lines would be going somewhat in this direction // both lines would be like that so they wouldnt intercept unless the lines were to go like /\ then they would intercept
