Question 4 of 10
If f(x) = 3x - 2 and g(x) = 2x + 1, find (f + g)(x).
A. 5x - 1
B. X-3
C. X-1
D. 5x-3
Answer:
Ii's letter A
Step-by-step explanation:
If functions f(x) = 3x - 2 and g(x) = 2x + 1 then (f+g)(x) value is 5x-1, Option A is correct.
What is a function?A relation is a function if it has only One y-value for each x-value.
The given functions are f(x) = 3x - 2 and g(x) = 2x + 1
We have to find the function (f+g)(x)
By property of the function (f+g)(x) = f(x) + g(x)
Now plug in the values of function f(x) and g(x)
(f+g)(x)= 3x-2+2x+1
Combine the like terms
(f+g)(x)= 5x-2+1
= 5x-1
Hence, if functions f(x) = 3x - 2 and g(x) = 2x + 1 then (f+g)(x) value is 5x-1, Option A is correct.

(x + y, 2) = (13, 2x – y)
Answer:
(x, y) = (5,8)
Step-by-step explanation:
Comparing the ordered pairs we get, x+y=13 and 2=2x-y. Solving it we will get, x=5 and y=8
UNESS has a contribution margin ratio of 0.25. UNESS operations income was sh.100 000blast year when the sales totaled sh. 1 000 000.What is UNESS fixed expense? A sh.250 000 B sh.350 000 C sh.150 000 D sh.225000
Answer:
D sh.225000
Step-by-step explanation:
Calculation to determine UNESS fixed expense?
Using this formula
Fixed expense=(Total sales - Operating income)*Contribution margin ratio
Let plug in the formula
Fixed expense=($1,000,000-$100,000)*0.25
Fixed expense=$900,000*0.25
Fixed expense=$225,000
Therefore UNESS fixed expense is $225,000
Business math problem, whats the formula for this, how do I do this?
========================================================
Explanation:
x = sticker price, which is some number larger than 9 (otherwise the store loses money)
x-9 = profit made per speaker
To get the gross margin percentage, we divide the profit over the sales (aka revenue). So we'll divide (x-9) over x
The expression (x-9)/x represents the gross margin in decimal form. Set this equal to 0.80 and solve for x
-----------------
(x-9)/x = 0.80
x-9 = 0.80x
x-0.80x = 9
0.20x = 9
x = 9/0.20
x = 45
The sticker price is $45
-------------------
If the sticker price is $45 per speaker, then the store owner gets 45-9 = 36 dollars in profit per speaker sold. The gross margin would be (profit)/(sales) = 36/45 = 0.80 = 80%
In other words, 80% of the revenue is profit (the remaining 20% is costs or expenses).

Match each explicit formula to its corresponding recursive formula.
(8) = 5(5)(1-1)
(n) = 3 +5(n-1)
(3) = 5+3(1-1)
7(n) = 3(5)(n-1)
$(n) = 5 +5(n-1)
f(1) = 5
(*) = 3;(n - 1), for 3
(1) = 5
(n) = f(n-1) +5, for n?
f(1) = 5
f(n) = f(n-1) + 3, for n?
Given:
The recursive formulae.
To find:
The correct explicit formulae for the given recursive formulae.
Solution:
If the recursive formula of a GP is [tex]f(n)=rf(n-1), f(1)=a, n\geq 2[/tex], then the explicit formula of that GP is:
[tex]f(n)=ar^{n-1}[/tex]
Where, a is the first term and r is the common ratio.
The first recursive formula is:
[tex]f(1)=5[/tex]
[tex]f(n)=3f(n-1)[/tex] for [tex]n\geq 2[/tex].
It is the recursive formula of a GP with a=5 and r=3. So, the required explicit formula is:
[tex]f(n)=5(3)^{n-1}[/tex]
Therefore, the required explicit formula for the first recursive formula is [tex]f(n)=5(3)^{n-1}[/tex].
If the recursive formula of an AP is [tex]f(n)=f(n-1)+d, f(1)=a, n\geq 2[/tex], then the explicit formula of that AP is:
[tex]f(n)=a+(n-1)d[/tex]
Where, a is the first term and d is the common difference.
The second recursive formula is:
[tex]f(1)=5[/tex]
[tex]f(n)=f(n-1)+5[/tex] for [tex]n\geq 2[/tex].
It is the recursive formula of an AP with a=5 and d=5. So, the required explicit formula is:
[tex]f(n)=5+(n-1)5[/tex]
[tex]f(n)=5+5(n-1)[/tex]
Therefore, the required explicit formula for the second recursive formula is [tex]f(n)=5+5(n-1)[/tex].
The third recursive formula is:
[tex]f(1)=5[/tex]
[tex]f(n)=f(n-1)+3[/tex] for [tex]n\geq 2[/tex].
It is the recursive formula of an AP with a=5 and d=3. So, the required explicit formula is:
[tex]f(n)=5+(n-1)3[/tex]
[tex]f(n)=5+3(n-1)[/tex]
Therefore, the required explicit formula for the third recursive formula is [tex]f(n)=5+3(n-1)[/tex].

Answer:
Equation: [tex]70=(x+3)x[/tex]
x = -10 or x = 7
x = 7 (width can't be negative)
x + 3 = 10
Step-by-step explanation:
Represent the width of the rectangle by x. "The length of a rectangle EXCEEDS the width by 3" means the length is 3 LONGER than the width, so the length is represented by the expression x + 3.
Area = (length)(width)
70 = (x + 3)x
Multiply out the right side.
[tex]70=x^2+3x\\x^2+3x-70=0[/tex]
Factor the left side.
[tex](x+10)(x-7)=0[/tex]
Each binomial could equal 0, so
[tex]x+10=0 \text{ or }x-7=0\\x=-10\text{ or }x=7[/tex]
The negative solution does not make sense as the width of a rectangle.
x = 7, making the length, x + 3 = 10
Answer:
Pls mark this as brainiest
Step-by-step explanation:
Area of the rectangle = length x breadth
consider 'x' to be width
therefore length = x+3
area = (x+3)*x
Area = 70 square
x = 7
x+3 = 7+3
= 10
verification
7 x 10
= 70

c. many-to-one
d. one-to-one
The given relation {(2,1), (4,2) (6,3) (8,4)} is one to many relation.
The other solution for this problem is given below.
The pattern is the sum of the two numbers plus the previous sum, i.e.
12 = 2+5 +(5)
21 = 3+6+ (12)
40 = 8+11 +21
These type of questions are part of reasoning and comes in random competitive exams which have multiple choice questions and therefore you have more than you want.
First , you need to multiply both numbers and then add the first number.
Therefore, 1+4= 1x4+1=5
2+5=2×5+2=12
3+6=3×6+3=21
What is the many to one relation?
A many-to-one relationship is where one entity (typically a column or set of columns) contains values that refer to another entity (a column or set of columns) that has unique values.
Hence,8+11=8×11+8=96
The other solution for this problem is given below.
The Solution for this is
1+4=5
1(4+1)=1(5)=5
2+5=12
2(5+1)=2(6)=12
3+6=21
3(6+1)=3(7)=21
Therefore we get,
8+11=8(11+1)=8(12)=96.
Therefore the given relation is any one to many relation.
