8. Which of the following correctly multiplies f(x) x g(x) if f(x) = 3x-1 and g(x) = 2x + 1?
A) f(x) x g(x) = 6x2 + x + 1
B) f(x) x g(x) = 5x
C) f(x) x g(x) = 6x2 + x-1
D) f(x) x g(x) = 5x2 + x-1
Answer:
C) f(x) x g(x) = 6x2 + x-1
Step-by-step explanation:
Multiplication of functions:
Two multiply two polynomial functions, we apply the distributive property(multiply each two terms and add).
In this question, we have that:
[tex]f(x) = 3x - 1, g(x) = 2x + 1[/tex]
The multiplication is:
[tex]f(x) \times g(x) = (3x - 1)(2x+1) = 3x*2x + 3x*1 -1*2x -1*1 = 6x^2 + 3x - 2x - 1 = 6x^2 + x - 1[/tex]

Expression represents five less a third of a number?
Answer:
[tex] \frac {1}{3}x - 5 [/tex]
Step-by-step explanation:
Let the unknown number be x.
Translating the word problem into an algebraic expression, we have;
[tex] \frac {1}{3}x - 5 [/tex]
Or
[tex] \frac {x}{3} - 5 [/tex]
Simplifying further, we have;
[tex] \frac {x}{3} = 5 [/tex]
Cross-multiplying, we have;
x = 15
Therefore, the above algebraic expression is five less a third of a number.
HELP PLEASE
A bus that seats 50 people was rented by a local club. As the bus fills with people, the price of each seat is lowered. What type of
trend would this be?
A) Positive
B) Negative
C)No trend
Answer: B) Negative
Step-by-step explanation:
Answer:
B) Negative
Step-by-step explanation:
The question states that as the number of people increases, the price of each seat decreases. Therefore this is a negative trend, because the increase in one variable leads to the decrease in the other variable.
Hope this helped!
Suppose that a large family has 14 children, including two sets of identical triplets, three sets of identical twins, and two individual children. How many ways are there to seat these children in a row of chairs if the identical triplets or twins cannot be distinguished from one another
Answer:
First, assume that we have 14 seats in a row.
Let's count the total number of combinations assuming that the 14 kids are differentiable.
In the first seat, we can sit only one child, the number of options is (14)
In the second seat, we can sit another child, in this case, the number of options is 13, because one child is already seated.
For the third seat, we will have 12 options.
for the fourth seat we will have 11 options, and so on.
The total number of permutations is equal to the product between the numbers of options for each case.
Then the total number of permutations is:
P = 14*13*12*11*...*3*2*1 = 14!
Now, we need to discount the permutations of the two sets of identical triplets:
a triplet has 3 elements, then the permutations of each set of triplets is:
p = 3*2*1 = 3!
Then if we discount two sets of triplets, we need to divide by:
d = 2*(3!)
We also have 3 sets of twins, the permutations for each set of twins is:
p = 2*1 = 2!
Then if we discount the 3 sets of twins, we need to by:
q = 3*(2!)
Then the total number of different combinations will be:
[tex]P = \frac{14!}{2*(3!)*3*(2!)} = 1,210,809,600[/tex]

LCM of (2^3×3×5) and (3×5) is
Answer:
120
Step-by-step explanation:
LCM of (2^3×3×5) and (3×5) is
The LCM of the expression will be the product of all the factors that are in both expressions
(2^3×3×5) = 2 * 2 * 2 * 3 * 5
(3 * 5) = 3 * 5
since 3 * 5 is common to both factors, we will not have to repeat it twice to get our LCM again. Hence the LCM is expressed as;
LCM = 2 * 2 * 2 * 3 * 5
LCM = 8 * 3 *5
LCM = 24 * 5
LCM = 120
Hence the required LCM is 120

_________________________________
( f o g )( x ) = f ( g(x) )
f ( g(x) ) = 1 / g(x) - 2
f ( g(x) ) = 1 / ( 4 / x ) - 2

I go to School for the Highly Gifted in Grand Prairie, Texas
Melinda is planning to attend a private university after she graduates from high school in 3 years. She is devising a plan to save money each month to help with the expenses of attending the university. The cost of attending the private university for one year is $22,500. Her family has promised to contribute $13,500 each year she is in school. Which plan shows the minimum amount of money Melinda must contribute to her savings to have enough money to pay for her first year of tuition? A: save $250 per month for the next 3 years B: Save $375 per month for the next 3 years C: Save $625 per month for the next 3 years D: Save $750 per month for the next 3 years
Answer:
A: save $250 per month for the next 3 years
Step-by-step explanation:
Melinda has three more years in high school as stated in the question.
One year private university tuition = $22,500
Support from family = $13,500
Amount that Melinda has to pay = $22,500 - $13,500 = $9000
Number of months in three years = 3 * 12 = 36 months
If she must save $9000 in 36 months
Then $x must be saved in 1 month
x = $9000/36
x = $250
A shopkeeper earns Rs. 380 in the first week, Rs. 660 in the second week and Rs. 860 in the third week. Earning is the quadratic function of number of week for which the earning is found. a. Find the quadratic function that fits the data
9514 1404 393
Answer:
e(w) = -40w^2 +400w +20
Step-by-step explanation:
A graphing calculator or spreadsheet can do the quadratic regression and help you find the formula. Here earnings (e) as a function of weeks (w) can be expressed by ...
e(w) = -40w^2 +400w +20
__
Further development
There are a couple of other ways you can go at this. One is to write equations for a, b, c using the standard form quadratic.
aw^2 +bw +c = e
a +b +c = 380 . . . . . . for week 1
4a +2b +c = 660 . . . for week 2
9a +3b +c = 860 . . . for week 3
The solution of this system of equations will give the coefficients of the quadratic. Your graphing calculator or any of several web sites can solve these equations for you.
__
Consider the differences between quadratic values for w = 1, 2, 3.
e2 -e1 = (4a +2b +c) -(a +b +c) = 3a +b
e3 -e2 = (9a +3b +c) -(4a +2b +c) = 5a +b
Then the second differences are ...
(e3 -e2) -(e2 -e1) = (5a +b) -(3a +b) = 2a
In the given set of numbers, the first differences are ...
660 -380 = 280 . . . . . . . call this d1
860 -660 = 200
And the second difference is ...
200 -280 = -80 . . . . . . . call this d2
From the above, we know that 2a = -80 ⇒ a = -40
and 3a +b = 280 = 3(-40) +b ⇒ b = 400
Finally, a+b+c = 380 = -40 +400 +c ⇒ c = 20
Then the generic solution is ...
a = d2/2
b = d1 -3a
c = e1 -a -b . . . . . where e1 is the first-week's earnings
All I know it’s not D and i’m super confused and I just want to go to bed
Answer:
C.
Step-by-step explanation:
Before graphing this equation we first need to isolate y on one side like so...
y + 2 = 3(x+1) ... distribute the 3 to both values inside the parenthesis
y + 2 = 3x + 3 ... subtract 2 on both sides
y = 3x + 1
Now that we have the y variable isolated we see that the slope of the function is 3, meaning that for every 1 unit right the line needs to move 3 units up. We also have the value where the line needs to cross the y-axis and that is 1. Using this information we see that the correct graph is C.

Answer:
no, b does not equal 5 in that equation
Step-by-step explanation:
if you solve for x, this is how it would look:
65/b + 8 x 4 = 20
65/b + 32 = 20
65/b = 20 - 32
65/b = -12
65 = -12b
-12b = 65
b = -65/12 (or -5 5/12)
