Answers
Answer:
Step-by-step explanation:
Table representing the function 'f' is,
x -3 2 3 7
y -2 8 10 18
In this table for every input value of x, there is a different output value.
So the function is one to one function.
Therefore, inverse of the given function will have the table as,
x -2 8 10 18
y -3 2 3 7

how can you tell that the inequality 3x - 1 > 3x +2 has no solution just by looking at the terms in the inequality
Answers
Answer:
same variable term on both sides
Step-by-step explanation:
Given
3x - 1 > 3x + 2 ( add 1 to both sides )
3x > 3x + 3 ( subtract 3x from both sides )
0 > - 3 ← not true, thus no solution
Because the variable term was the same on both sides then it is eliminated

Scouting Troops in Morgan Country are putting on a crab feed to raise money for camp. They offer a complete crab dinner as well as a vegetraian option. One Troop member sold tickets for 12 crab meals and 23 vegetarian meals, with total receipts of $916. Another sold tickets for 12 crab meals and 12 vegetarian meals, bringing in a total of $696. How Much do the 2 types of tickets costs?
Answers
Answer:
cost of crab meals = $20
cost of vegetarian meals = $38
Step-by-step explanation:
Let
x = cost of crab meals
y = cost of vegetarian meals
Troop A
12 crab meals and 23 vegetarian meals, with total receipts of $916.
12x + 23y = 916
Troop B
12 crab meals and 12 vegetarian meals, bringing in a total of $696
12x + 12y = 696
12x + 23y = 916 (1)
12x + 12y = 696 (2)
Subtract (2) from (1)
23y - 12y = 916 - 696
11y = 220
y = 220/11
= 20
y = 20
Substitute y = 20 into (1)
12x + 23y = 916
12x + 23(20) = 916
12x + 460 = 916
12x = 916 - 460
12x = 456
x = 456/12
= 38
x = 38
cost of crab meals = $20
cost of vegetarian meals = $38

Your principal amount is $450 your interest rate is 6% and your time is 8 years what is your interest earned after eight years what is your new total amount earned after 8 years
Answers
Answer:
Results are below.
Step-by-step explanation:
Giving the following information:
Principal= $450
Number of periods= 8 years
Interest rate= 6%
We will determine the interest earned and future value using simple interest and compound interest:
Simple interest:
I= P*r*t
I= 450*0.06*8= $216
Total Future Value= I + P
Total Future Value= 216 + 450= $666
Compound interest:
I= [P*(1+r)^t] - P
I= [450*(1.06^8)] - 450= $267.23
Total Future Value= P*(1+r)^t
Total Future Value= 450*1.06^8
Total Future Value= $717.23

A. $105 B. $112 C. $175 D. $525
Answers
Answer:
A. $105
Step-by-step explanation:
Given
total charge= $700 per concert
solution
If Fredrick receives $175 of that money, the balance will be
$700-$175= $525
The balance will be shared by the 5 members
Hence each of them will take
525/5=$105

What is an EQUATION?Equations are mathematical statements with two algebraic expressions surrounding the equals (=) sign on either side. It demonstrates the equality of the relationship between the expressions written on the left and right sides. We have LHS = RHS (left hand side = right hand side) in every mathematical equation. To determine the value of an unknown variable that represents an unknown quantity, equations can be solved. A statement is not an equation if it has no "equal to" sign. It will be regarded as a phrase.Let's use the quantity "X" as the variable in our inquiry. The number is - since 21 is less than 11 times "X," which results in seven times a number that has been decreased by 29.
11 * X-21= 7*X-2911X-21=7X-294X=-8Divide both sides of the equation by the coefficient of variableX= -2Hence we can say that after forming the equation according to the question the answer is, X=-2.

f(x) = (x + 2)(x − 1)(x − 3)
f(x) = (x − 2)(x + 1)(x + 3)
f(x) = (x + 2)(x + 1)(x + 3)
f(x) = (x − 2)(x − 1)(x − 3)

Somebody Please solve this question without using L Hospital rule.
Evaluate if:
Answers
Answer:
1/2
Step-by-step explanation:
Given that,
[tex]\lim_{n \to 1} (\dfrac{1+\cos\pi x}{\tan^2\pi x})[/tex]
Using L Hospital's rule to find it :
[tex]\lim_{n \to a} \dfrac{f(x)}{g(x)}= \lim_{n \to a} \dfrac{f'(x)}{g'(x)}[/tex]
We have,
a = 1, [tex]f(x)=1+\cos\pi x, \ \ g(x)=\tan^2\pi x[/tex]
[tex]f'(x)=\dfrac{d}{dx}(1+\cos\pi x)\\\\=-\pi \sin \pi x\ .....(1)[/tex]
[tex]g'(x)=\dfrac{d}{dx}(\tan^2\pi x)\\\\=2\tan\pi x\times \sec^2\pi x\times \pi\ .....(2)[/tex]
From equation (1) and (2) :
[tex]\lim_{n \to 1} \dfrac{f(x)}{g(x)}= \lim_{n \to 1} \dfrac{-\pi \sin\pi x}{2\tan \pi x\times \sec^2\pi x \times \pi}\\\\\lim_{n \to 1} \dfrac{-\pi \sin\pi x}{2\tan \pi x\times \sec^2\pi x \times \pi}\\\\=\lim_{n \to 1} \dfrac{-1}{2}\times\cos^3\pi x\\\\=\dfrac{-1}{2}\times \cos^3\pi \\\\=\dfrac{1}{2}[/tex]

Answer:
line y = x(4, -2), (2, 0), (-2, 3)Step-by-step explanation:
The graph of an inverse relation is the reflection of the graph of the relation over the line y = x. That interchanges the coordinates of the points of the function. (-2, 4) becomes (4, -2) when so reflected, for example.

First, convert 15% to a decimal.
15% / 100 = 0.15
Then, multiply.
0.15 * 12.40 = $1.86
Since 15% of 12.40 is $1.86, then Jamie left a $1.86 tip.

55°
Step-by-step explanation:
130° is an external angle to the small triangle at lower left, so is the sum of the remote interior angles. The unmarked interior angle at the bottom of that triangle is then 130° -30 = 100°.
That is an exterior angle of the large triangle that has remote interior angles of 45° and x°. So, ...
x° + 45° = 100°
x° = 100° -45°
x° = 55°
_____
Alternate solution
The sum of the interior angles of a quadrilateral is 360°. Three of the angles in the bounding quadrilateral are x°, 45°, 30°. The fourth is the reflex angle that is (360° -130°) = 230°. So, we have ...
x° +45° +230° +30° = 360° . . . . . angles CCW from lower right
x° = 360° -305°
