For a group trip, a travel agency charges $300 per person. Write an expression to show the cost of a group trip for p people.
Answer:
c = 300p
Step-by-step explanation:
What we know:
For a group trip, a travel agency charges $300 per person.
How equations work are:
dv = k(iv)
The cost of the trip is the dependent variable, so that's on the left side of the equation. (I've represented that with c)
c = k(iv)
The independent variable is people, so that's on the right side. (represent with p)
c = kp
Our constant (k) is 300.
c = 300p is the full equation.
Answer:
Nice c

Explain whether you agree of disagree about open book tests being more difficult than traditional tests. What can you do to better prepare for your next open book test? OUT OF THE QUESTION ITS ACADEMIC SUCCESS FOR MY CLASS
Answer:
I disagree. Open book tests, you can see the answers, and the test usually goes by pretty quick and smoothly because of this. Traditional tests, sometimes you don't even get notes, and so you can struggle more with that then with open book tests.
Step-by-step explanation:
I got 100% on Edge!
Answer:
I believe that open book test are easier simply because the answers are right in front of you all you have to do is search for them and not copy directly from the book. One way you can prepare for it is to memorize what information is on each page so you don't constantly flip back and forth from the pages

ahmad drove 756 miles in 12 hours, at the same rate how many miles would he drive in 7 hours?
Find his rate by dividing total miles by hours:
756 miles / 12 hours = 63 miles per hour.
Multiply the rate by number of hours:
63 x 7 = 441 miles
Answer:
441 miles
Step-by-step explanation:
756 deived by 12 = 63x7 =
441 miles
A shopkeeper buys 10 television sets from a retailer at a rate of Euro 15,000 per set. He sells half of them at a profit of 25 % and rest half at a loss of 20%. Find the overall profit/loss faced by the shopkeeper.
Answer: Profit of $3,750
Step-by-step explanation:
Sold half of the sets at a profit of 25%;
= (15,000 * 5 sets) * 25%
= $18,750
Sold the other half at a loss of 20%;
= (15,000 * 5) * 20%
= $15,000
Profit (loss) = 18,750 - 15,000
= $3,750

Graph the following system of equation
y= 3x + 11
y= -4x + 4
Answer:
Step-by-step explanation:
Answer:
These equations describe two lines that intersect at the point (-1, 8), one of them with a slope of 3, the other with a slope of -4.
Step-by-step explanation:
We can find the point where these two lines intersect by taking one of the equations, solving it for x, and substituting it into the other equation.
[tex]y = -4x + 4\\-4x = y - 4\\4x = 4 - y\\x = 1 - \frac{y}{4} \\\\y = 3x + 11\\y = 3(1 - \frac{y}{4}) + 11\\y = 3 - \frac{3y}{4} + 11\\y + \frac{3y}{4} = 3 + 11\\\frac{4y}{4} + \frac{3y}{4} = 14\\\frac{7y}{4} = 14\\y = \frac{4}{7} * 14\\y = 4 * \frac{14}{7}\\y = 4 * 2\\y = 8[/tex]
Now we can plug that into our first equation to find x
[tex]x = 1 - \frac{y}[4}\\x = 1 - \frac{8}[4}\\\\x = 1 - 2\\x = -1[/tex]
So these lines intersect at the point (-1, 8), one of them with a slope of 3, the other with a slope of -4

Which equation represents the line that is parallel to segment RS in the triangle below and passes through point T?
Answer:
[tex]y = \frac{1}{2}x +4[/tex]
Step-by-step explanation:
Given:
[tex]R = (0,0)[/tex]
[tex]S= (8,4)[/tex]
[tex]T = (-2,3)[/tex]
First, we have that the line is parallel to RS.
This means that the line has the same slope as RS and the slope of RS is calculated as follows:
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
[tex]m = \frac{4-0}{8-0}[/tex]
[tex]m = \frac{4}{8}[/tex]
[tex]m = \frac{1}{2}[/tex]
So, the line has a slope of [tex]m = \frac{1}{2}[/tex]
Next, we have that the line passes through [tex]T = (-2,3)[/tex].
The equation of the line is then calculated using the following formula
[tex]y - y_1 = m(x - x_1)[/tex]
[tex]y - 3 = \frac{1}{2}(x - (-2))[/tex]
[tex]y - 3 = \frac{1}{2}(x +2)[/tex]
Open bracket
[tex]y - 3 = \frac{1}{2}x +1[/tex]
Make y the subject
[tex]y = \frac{1}{2}x +1+3[/tex]
[tex]y = \frac{1}{2}x +4[/tex]

Hello!
[tex]\large\boxed{f^{-1} = \frac{5x+2}{4x-2}, f^{-1}(3) = \frac{17}{10} }[/tex]
[tex]f(x) = \frac{2x +2}{4x - 5}[/tex]
Find the inverse by swapping the x and y variables:
[tex]y = \frac{2x +2}{4x - 5}\\\\x = \frac{2y +2}{4y - 5}[/tex]
Begin simplifying. Multiply both sides by 4y - 5:
[tex]x(4y - 5) = 2y + 2[/tex]
Start isolating for y by subtracting 2 from both sides:
[tex]x(4y - 5) -2 = 2y[/tex]
Distribute x:
[tex]4yx - 5x - 2 = 2y[/tex]
Move the term involving y (4yx) over to the other side:
[tex]- 5x - 2 = 2y - 4yx\\\\[/tex]
Factor out y and divide:
[tex]- 5x - 2 = y(2 - 4x)\\\\y = \frac{-5x-2}{-4x+2} \\\\y = \frac{-(5x + 2)}{-(4x - 2)} \\\\y^{-1} = \frac{5x + 2}{4x - 2}[/tex]
Use this equation to evaluate [tex]f^{-1}(3)[/tex]
[tex]f^{-1}(3) = \frac{5(3) + 2}{4(3) - 2} = \frac{17}{10}[/tex]
