Step-by-step explanation:
4x-5y=6 for y
Solve the equation for the specified variable
Answer:
[tex]y = - \frac{4}{5} x + \frac{6}{5} [/tex]
Step-by-step explanation:
First subtract 4x on both sides in order to get -5y alone. Now you have -5y = 4x + 6 (since neither 6 nor 4x are like terms). Now divide -5 on both sides in order to get rid of it, so we can get y by its self. Now you have y = -4/5 x + 6/5
Hope this makes sense. Also please tell me if I'm wrong and I'll be happy to look at it again for ya :)
Two buses leave a station at the same time and travel in opposite directions. One bus travels 17 mi/h slower than the other. If the two buses are 345 miles apart after 3 hours, what is the rate of each bus? Please help!
Answer:
...,....................
Answer:
one bus travels at 66mi/hr and the other bus at 49mi/hr
Step-by-step explanation:
Let's assume one bus, A is traveling at x mi/hr and the other bus, B at x+17 mi/hr
after 3hrs, bus A will have covered 3x miles and bus B will have covered 3(x+17) miles.
the buses are 345 mils apart but from the same origin,
meaning Distance of A + Distance of B =345 miles
3x+3(x+17)=345
x=49
for bus A
and x+17=66 for bus B
Historically, the course covering material and energy balances at many universities is challenging. Many students, however, are resilient. The historical data for Professor Testor's classes indicate that about 70% of the students (new students plus students who are retaking the course) pass the class. Of the students who do not pass, 75% register to take the class again the following semester. Round your answers to the following questions to the nearest integer. If 125 new students (students that have never taken the class before) register for the class each semester, what is the total number of students taking the class

Brittany brought her collection of Map Mosaics jigsaw puzzles to a secondhand store to sell. She was paid cash for all 8 puzzles in her collection. Before she left, Brittany used $7.25 of her earnings to purchase a used board game. She had $12.75 remaining. Which equation can you use to find the amount of money, p, Brittany received for each puzzle in her collection?
Answer:
[tex]p=(12.75+7.25)/8[/tex]
Step-by-step explanation:
The money she earned is the remaining money plus the board game price. With the total profit, you divide by the 8 puzzles
Brittany received an amount of $2.50 for each puzzle in her collection.
What is the equation?The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.
Let's assume the amount of money Brittany received for each puzzle in her collection is p dollars.
Then the total amount of money she received for 8 puzzles will be 8p dollars.
If she used $7.25 to buy a board game, then the amount of money she had before purchasing the board game was 12.75 + 7.25 = $20.
We know that the total amount of money Brittany received for 8 puzzles was 8p dollars. So we can write an equation:
8p = 20
Divide both sides by 8:
p = 2.5
Therefore, he received $2.50 for each puzzle in her collection.

Jazelle Momba wants to visit her family in Zimbabwe in 2025, which is 6 years from now. She knows that it will cost approximately $8,000 including flight costs, on-the-ground costs, and extra spending money to stay for 4 months. If she opens an account that compounds interest at 4% semiannually, how much does she need to deposit today to cover the total cost of her visit?
9514 1404 393
Answer:
$6307.95
Step-by-step explanation:
The compound interest formula can help with that.
A = P(1 +r/n)^(nt) . . . . value of principal P at rate r for t years, compounded n times per year.
P = A(1 +r/n)^(-nt) = $8000(1 +0.04/2)^(-2·6) = $8000(1.02^-12) = $6307.95
Momba needs to deposit $6307.95 today to have $8000 in 6 years.

he product of two whole numbers is 864 and their sum is 60 . What are the two numbers?
Answer:
Step-by-step explanation:
xy = 864
x + y = 60 Solve for y in the second equation
y = 60 - x
x * (60 - x) = 864 Remove the brackets.
60x - x^2 = 864 Put in order of powers and subtract 864
-x^2 + 60x - 864 =0 Multiply through by -1
x^2 - 60x + 864 = 0
This factors
(x - 36)(x - 24) = 0
Either
x - 36 = 0 in which case
x = 36
or
x - 24 = 0
x = 24
The two numbers are x = 36 and y = 24
of x = 24 and y = 36

2 log x - log y - 2 log z as a single logarithm
Answer:
log ( x^2/(yz^2))
Step-by-step explanation:
2 log x - log y - 2 log z
We know a log b = log b^a
Rewriting
2 log x = log x^2 and 2 log z = log z^2
log x^2 - log y - log z^2
Rewriting
log x^2 - (log y + log z^2)
We know that log a + log b = log (a*b)
log x^2 - (log (y z^2))
And we know log a - log b = log (a/b)
log ( x^2/(yz^2))

log(x^2)−log(y)−log(z^2)
Use the quotient property of logarithms, logb (x)−logb (y)=logb (x/y)

Use the quotient property of logarithms, logb(x)−logb(y)=logb (x/y)

[tex]y = x + \pi[/tex]
Step-by-step explanation:
We need to find the slope of the line tangent to y at [tex]x=-\pi[/tex] and we can do that by calculating the derivative of y at that point. We know that
[tex]y'(x) = \dfrac{d}{dx}(\tan{x}) = \sec^2{x}[/tex]
and
[tex]y'(-\pi) = \sec^2(-\pi) = 1[/tex]
To find the equation of the tangent line, we know that the line passes through the point [tex](-\pi, 0)[/tex] so we can write the slope-intercept form of the line's equation as
[tex]0 = (-\pi) + b \Rightarrow b = \pi[/tex]
Therefore, the equation of the line tangent to the point [tex]x = -\pi[/tex] is
[tex]y = x + \pi[/tex]

Answer:
Step-by-step explanation:
Step 1:
Sum of fractions in the denominator making cross product:
d / r1 + d / r2
Resulting:
d * r2 + d * r1 / (r1 * r2)
Step 2:
Multiply numerator and denominator by the following expression:
(r1 * r2) / (d * r2 + d * r1)
Step 3:
Take common factor in the denominator of the expression in step 2.
Resulting:
(d * r2 + d * r1) = d * (r2 + r1)

Step-by-step explanation:
You just keep dividing by 2
If I'm wrong, sorry
Answer:
0.046875 aka 3/64
Step-by-step explanation:
In a geometric sequence, each term will be related to the previous term by undergoing either multiplication or division.
In this case, each case is exactly 1/2 of the previous term. 12 is half of 24, and 6 is half of 12. By continuing this sequence, we get
1: 24
2: 12 (24 * 1/2)
3: 6 (12 * 1/2)
4: 3 (6 * 1/2)
5: 3/2 (3 * 1/2)
6: 3/4 (3/2 * 1/2)
