BRAINLIEST IF CORRECT
Answers
Answer:
Smaller number: 12
Greater number: 31
Step-by-step explanation:
Hi there!
Let x equal to the smaller number.
Let y be equal to the greater number.
1) Translate the information into equations
"One is 7 more than twice the other"
⇒ [tex]y=2x+7[/tex]
"The sum of the numbers is 43"
⇒ [tex]x+y=43[/tex]
2) Use substitution to solve for the smaller number
[tex]x+y=43[/tex]
Plug the equation [tex]y=2x+7[/tex] into the above equation
[tex]x+(2x+7)=43\\x+2x+7=43\\3x+7=43[/tex]
Subtract both sides by 7
[tex]3x+7-7=43-7\\3x=36[/tex]
Divide both sides by 3 to isolate x
[tex]\frac{3x}{3} = \frac{36}{3} \\x=12[/tex]
Therefore, the smaller number equates to 12.
3) Use substitution to solve for the greater number
[tex]x+y=43[/tex]
Plug in x as 12
[tex]12+y=43[/tex]
Subtract both sides by 12 to isolate y
[tex]12+y-12=43-12\\y=31[/tex]
Therefore, the greater number equates to 31.
I hope this helps!

A. 119
B. 120
C. 121
D. 122
no spam answers please and kindly explain ur answer.
Answers
Given x+x-¹ = 11
now square both the side
(x+x-¹)² = 11²
now open the bracket of RHS and apply (a+b)²
you'll get,
x²+2x/x+ 1/x² =121
simplify above equation you'll get,
x²+ 2 + x-² = 121
shift the equation,
x² + x-² = 121 - 2
x² + x-² = 119 !
Find the inverse function.
x - 3
f(x) =

5
f-1(x) = [ ? ]x + [ ]
Answers
Steps
Solve for the inverse function of
f(x)=((x-3)/5)+2
First one should replace the variables so
that f(x)=((x-3)/5)+2 becomes:
x=((y-3)/5)+2 (this isn’t necessary, it just makes it easier for those to remember the variable they are looking for when first learning about inverses) —> regardless, we are searching for y.
So doing regular algebra, we get:
x=((y-3)/5)+2
x-2=((y-3)/5)
5(x-2)=y-3
5(x-2)+3=y
Thus, the inverse: f(x)^-1 = 5x-7

Determine if the sequence below is arithmetic or geometric and determine the
common difference / ratio in simplest form.
12, 6, 3, ...
Answers
Answer:
The sequence is geometric
The common ratio is 0.5
Step-by-step explanation:
In the arithmetic sequence, there is a common difference between each two consecutive terms
In the geometric sequence, there is a common ratio between each two consecutive terms
Let us check the given sequence
∵ The first 3 terms are 12, 6, 3
∵ 6 - 12 = -6
∵ 3 - 6 = -3
∵ There is no common difference between the consecutive terms
∴ The sequence is not an arithmetic sequence
∵ 6 ÷ 12 = 0.5
∵ 3 ÷ 6 = 0.5
∴ There is a common ratio between each two consecutive terms
∴ The sequence is a geometric sequence
∴ The common ratio is 0.5
