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

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)

[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]

The graph of the two functions is shown above.

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

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 :)

Answer:

$54 for fees

$1500 for commission

$29554 in total

Step-by-step explanation:

They will have $28000 regardless.

The commission is 2% so you multiply 0.02 (which is equivalent to 2%) to $75000, so he earns $1500. He sold 6 sales so he you multiply 6 by $9 and you get $54.

I don't know exactly what your asking but

$54 for fees

$1500 for commission

$29554 in total

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))

Answer:

[tex]log\frac{x^2}{yz^2}[/tex]

Step-by-step explanation:

Simplify 2log(x) by moving 2

inside the logarithm.

Simplify 2log(x) by moving 2

inside the logarithm.

log(x^2)−log(y)−2log(z)

Simplify −2log(z)

by moving 2

inside the logarithm.

log(x^2)−log(y)−log(z^2)

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

[tex]log\frac{x^2}{y} - log(z^2)[/tex]

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

[tex]log (\frac{x}{y})/( \frac{1}{z^2}}][/tex]

Multiply the numerator by the reciprocal of the denominator.

[tex]log\frac{x^2\\ }{y}.\frac{1}{z^2}[/tex]

Combine.

[tex]log\frac{x^2*1\\ }{yz^2}[/tex]

Multiply [tex]x^{2}[/tex] by 1

[tex]log\frac{x^2}{yz^2}[/tex]

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)

7. 3/8 (3/4 * 1/2)

8. 3/16 (3/8 * 1/2)

9. 3/32 (3/16 * 1/2)

10. 3/64 (3/32 * 1/2)

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.

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.
