Write the equation of the line in slope-intercept form that has a slope of -5/2 and passes through the point (14,-39)
Answer:
Step-by-step explanation:
The equation of the line in point-slope form;
y+39 = (-5/2)(x-14)
Rearrange to solve for y:
y+39 = (-5/2)x + 35
y = (-5/2)x + 4

the bases of a trapezoid are 8 and 6 inches it's height is 5 inches what is the area of the trapezoid?
Answer:
35 in^2
Step-by-step explanation:
The area of a trapezoid is the average of the bases times the height.
Base 1: 8, Base 2: 6, Height: 5
(8 + 6)/2 = 7
7 * 5 = 35 in^2
The owner of a luxury motor yacht that sails among the 4000 Greek islands charges $460 per person per day if exactly 20 people sign up for the cruise. However, if more than 20 people (up to the maximum capacity of 90) sign up for the cruise, then each fare is reduced by $7 per day for each additional passenger. Assume at least 20 people sign up for the cruise, and let x denote the number of passengers above 20. (a) Find a function R giving the revenue per day realized from the charter. R(x)
Answer:
R(x) = (460 * 7x)*(20+ x)
Step-by-step explanation:
If exactly 20 people sign up :
Charge per person = $460
For passengers after 20:
At number of passengers = 20 ;
Cost = (fee * discount * number of additional passesengers) * (20 + Number of additional passengers
Let number of additional passengers after 20 = x
R(x) = ($460 * $7x) * (20 + x)
Hence,
R(x) = (460 * 7x)*(20+ x)

Answer:
Step-by-step explanation:
It's not A since that means 1 3/4 or 7/4. That isn't a possible answer since 7/4 is greater than 1.
B: not the answer. You'll make 72000 almost 1000 times bigger if you use B.
C: same reason as B. Anything over 1 will make 72033 larger, not smaller
E: 12/8 > 1. It can't work.
The answer is d . Try it on your calculator. Anything between 0 and 1 make make any number smaller. (include zero, don't include 1).

What is the perimeter of this shape
9514 1404 393
Answer:
72.6 cm
Step-by-step explanation:
It is the perimeter of the overall rectangle plus twice the depth of the notch.*
P = 2(L+W) +2d
P = 2(16 cm + 13 cm + 7.3 cm) = 2(36.3 cm)
P = 72.6 cm
The perimeter of the shape is 72.6 cm.
_____
* You may be able to visualize this if you imagine the bottom (top) of the notch translated out (down) to the edge of the rectangle. That translation does not affect the length of the line segment, but helps convince you that only the two legs of the notch are added to the perimeter of the rectangle.
The local appliance store is advertising a 17% off sale on a new flat-scree TV. If the sale price is $664, what was the original price of the flat-screen TV?
Answer:
the original price = $800
Step-by-step explanation:
To find the fraction of the original price, subtract 0.17 from 1.00, obtaining 0.83. Then 0.83n = $664 yields n = the original price = $800

A frame around a family portrait has a perimeter of 94 inches. The length of the frame is 7 inches less than twice the width. Find the length and width of the frame.
Step-by-step explanation:
Let l be the length and w be the width of the frame.
We have 2(l + w) = 94 and l = 2w - 7.
Therefore 2[(2w - 7) + w] = 94.
=> 3w - 7 = 47
=> 3w = 54
=> w = 18
l = 2(18) - 7 = 36 - 7 = 29
Hence the length of the frame is 29in and the width of the frame is 18in.

Find the slope
Answer:
3
Step-by-step explanation:
the slope of an equation (y=mx+b) is always "m", or the coefficient right infront of x. in this case, y=3x-7, 3=m, -7=b. m is the slope, so the slope is 3.

t-shirts for $2 and shorts for $4. the total sales were $600. they sold four times more tshirts than shorts how many tshirts and shorts did they sell?
Answer:
T-shirts: 200
Shorts: 50
Step-by-step explanation:
To solve, set up an equation using two variables to represent the number of t-shirts and shorts sold. Let x = t-shirts sold. Let y = shorts sold. 2x + 4y = 600. We know that x will be 4 times greater than y, so we can plug in some guesses that seem reasonable and use the equation to test our theories. My first guess was 50 shorts, which by luck was the correct answer. These problems can be tricky, but setting up an equation can prove to be a great help.

Answer:
66 are chocolate. 120x1.45 66
The number of cupcakes sold that day was chocolate flavored will be 54.
What is the percentage?The quantity of anything is stated as though it were a fraction of a hundred. A quarter of 100 can be used to express the ratio. Per 100 is what the term percent signifies. The symbol '%' is used to symbolize it.
A bakery sold a total of 120 cupcakes in a day, and 45% of them were chocolate flavored.
Then the number of cupcakes sold that day were chocolate flavored will be
Let x be the number of the cupcakes sold that day that was chocolate flavored.
x = 45% of 120
x = 0.45 × 120
x = 54
Thus, the number of cupcakes sold that day was chocolate flavored will be 54.

A quadratic function is described by the equation f(x) = (x - 3) ^ 2 Which statement about the graph of the function is true?
A The only zero of the function is 3 which is where the graph of the function intersects the x-axis
В. The only zero of the function is 3 which is where the graph of the function intersects the y-axis.
C.The only zero of the function is , which is where the graph of the function intersects the x-axis.
D.The only zero of the function is is where the graph of the function intersects the y-axis .
Answer: A) The only zero of the function is 3 which is where the graph of the function intersects the x-axis
Step-by-step explanation:
Remember, a quadratic function which has roots x = a, and x = b, can be written as:
p(x) = A*(x - a)*(x - b)
Where A is the leading coefficient. This is the factorized form of a quadratic.
We have the function:
f(x) = (x - 3)^2
Now, we could rewrite this as:
f(x) = (x - 3)*(x - 3) = 1*(x - 3)*(x - 3)
Then we wrote f(x) in its factorized form, from this, we can see that the roots of the function are x = 3, and x = 3 (we have the same root two times)
Then the only root of f(x) is x = 3.
Remember that a root (also called a zero) is the value of x where the function intersects the x-axis. then the correct option here is:
A) The only zero of the function is 3 which is where the graph of the function intersects the x-axis

The price of a computer is reduced by 17.5%. The reduced price is £264 by how much is the price reduced
Answer:
Step-by-step explanation:
100%-17.5%= 82.5%
82.5% (divide) 82.5%= 1%
so (1% of the orginal price)=
£264 (divide) 82.5%= £320= original price
The price of the computer is reduced by £56 which is 17.5% of £320.
What is the percentage?A percentage is a value per hundredth. Percentages can be converted into decimals and fractions by dividing the percentage value by a hundred.
Given, The price of a computer is reduced by 17.5% and the reduced price is £264.
Let the original price be '£x'.
So, (100 - 17.5)% = 82.5% of '£x' is £264.
∴ (82.5/100)×x = 264.
0.825x = 264.
x = 264/0.825.
x = £320.
So, The price reduced is (320 - 264) = £56.
