Answer:
3e+10f-9
Step-by-step explanation:
We have to collect the matching letters
4e-e is 3e
2f+8f is 10f
-9 is the only number
In algebra, we always write them in alphabetical order, with any lonely numbers last
So we have 3e+10f-9

What is the reciprocal, multiplicative inverse of -14/15
Answer:
reciprocal = -14/15
= 15/-14
multiplicative inverse = [tex]\frac{-14}{15}[/tex] × [tex]\frac{15}{-14}[/tex] = [tex]\frac{-210}{-210}[/tex] = 1
= [tex]\frac{15}{-14}[/tex]

69. The O'Brien's had $400.0 in a special
checking account for installment payments.
After paying $40.00 a month for three months
and $20.00 a month for two months. How
much was left in the account?
Hello :D
$40.00 x 3 = $120.00
$20.00 x 2 = $40.00
$120.00 + $40.00 = $160.00
$400.00 - $160.00 = $240.00
There is $240.00 left in the account.

Answer:
In the first two parts you have filled in the table and found the correct graph of the function y = x² - x - 2, which is C.
Now, to solve for part C, you need to consider y = 3 value on the graph C.
Corresponding points on x-axis are the points you are looking for.

Simplify 56:40:16 (show your working)
9514 1404 393
Answer:
7 : 5 : 2
Step-by-step explanation:
The ratio is reduced by dividing by the greatest common factor. Since you know your multiplication tables, you know each of the numbers is a multiple of 8. When you divide that out, you get the reduced form.
56 : 40 : 16 = 56/8 : 40/8 : 16/8 = 7 : 5 : 2
if 4 is added to the numerator of the fraction 2/5, what number must be added to the denominator to make the fraction equivalent to 1/2?
Answer:
7
Step-by-step explanation:
Let X be the number...
2+4/5+X=1/2
6/5+X=1/2
12=5+X
X=7
Answer:
7
Step-by-step explanation:
By adding 4 to the numerator 2, we get 6 / 5.
Since 1 / 2 = 0.5, we need to find a number that we can divide 6 by to get 0.5.
Since 0.5 is half of a unit, we just need to find a number which it's half is 6.
6 * 2 = 12 (meaning 6 is half of 12), so 6 / 12 = 0.5 meaning 6 / 12 it's equivalent to 1 / 2.
12 - 5 = 7, so we need to add seven to the denominator to make the fractions equivalent.

54/75 equals x/750. 75 times 10 equals 750 so 54 times 10 equals 540 middle school students
What are the domain and range of function p within the context of Melissa’s garden?
Drag the values to the correct locations on the image. Each value can be used more than once, but not all values will be used.
When a function is plotted, the domain and the range of the function are the x-coordinate and the y-coordinate respectively. The domain and range of the assumed function for Melissa's garden are: [tex]x = (2,\infty][/tex] and [tex]p(x) = (0,\infty][/tex], respectively.
The function for Melissa's garden is not given. So, I will give a general explanation to calculate domain and range.
The domain is all possible values the independent variables of a function can take while the range is all possible values the dependent variables of a function can take
Assume the function of Melissa's garden is:
[tex]p(x) = x(x - 2)[/tex]
Start by equating the function to 0
[tex]x(x - 2) = 0[/tex]
Split
[tex]x = 0\ or\ x - 2 = 0[/tex]
Solve
[tex]x = 0\ or\ x = 2[/tex]
The above values of x will give [tex]p(x) = 0[/tex]
Because it is a garden, the length of the garden cannot be 0 or less.
So, the domain of the function is:
[tex]x = (2,\infty][/tex]
This means that the domain starts from a value greater than 2 (e.g. 3) and ends at infinity
To calculate the range, we substitute [tex]x = (2,\infty][/tex] in the function
[tex]x = 2[/tex] means
[tex]p(2) = 2 \times ( 2- 2) = 0[/tex]
[tex]x = \infty[/tex] means
[tex]p(2) = \infty \times (\infty- 2) = \infty[/tex]
So, the range of the function is:
[tex]p(x) = (0,\infty][/tex]
This means that the domain starts from a value greater than 0 (e.g. 1) and ends at infinity

Answer:
The range is 0, infinity and the domain is 0,12
Step-by-step explanation:
A woman works at a law firm in city A which is about 40 miles from city B. She must go to the new law library in city B to get a document. Find how long it takes her to drive round-trip if she averages 50 mph. Use the distance formula, d=rt, where d= Distance traveled, r= rate, and t=time.
The total time taken by the woman to get the document in the round trip is 1.6 hours.
The given parameters;
distance between city A and city B, = 40 miles
the average speed of the woman, v = 50 miles per hour
To find:
the total time taken by the woman during the journeyThe total distance of the round trip is calculated as follows;
From A to B = 40 milesFrom B back to A = 40 milesTotal distance of the round trip = 40 miles + 40 miles = 80 miles
The average speed of the woman is given as;
[tex]average \ speed \ = \frac{total \ distance }{total \ time } \\\\total \ time = \frac{total \ distance }{average \ speed} \\\\total \ time = \frac{80 \ miles }{50 \ miles/hr} \\\\total \ time = 1.6 \ hours[/tex]
Thus, the total time taken by the woman to get the document in the round trip is 1.6 hours.

A motorboat travels 448 kilometers in 8 hours going upstream and 440 kilometers in 5 hours going downstream. What is the rate of the boat in still water and what is the rate of the current?
9514 1404 393
Answer:
boat: 72 km/hcurrent: 16 km/hStep-by-step explanation:
The speed difference between boat and current is the upstream rate:
(448 km)/(8 h) = 56 km/h
The sum of speeds of boat and current is the downstream rate:
(440 km)/(5 h) = 88 km/h
The rate of the boat is half the sum of these:
(56 +88)/2 = 72 . . . km/h
The rate of the current is half their difference:
(88 -56)/2 = 16 . . . km/h
The rate of the boat is 72 km/h; the rate of the current is 16 km/h.
