The graph of a non-invertible function passes through the points (−2,4), (0,2), and (3,−2).
How is the inverse of this function graphed?
9514 1404 393
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.

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
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

Jamie went to dinner. Her meal cost $12.40. She wanted to leave a 15%
tip. How much was her tip?
Answer:
Hi there! The answer is $1.86. Hope this helps! c:
Step-by-step explanation:
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.
a student earns $11.75 per hour for gardening. if she worked 21 hours this month, then how much did she earn?
Answer:
$246.75
Step-by-step explanation:
11.75 x 21 = 246.75
hope this helps <3
Answer:
If the student worked 21 hours this month, she will earn $246.75.
Step-by-step explanation:
Let [tex]x[/tex] equal hours.
If the student earns $11.75 per hour, we can represent this with the expression:
[tex]11.75x[/tex]
If she worked 21 hours this month, then:
[tex]x=21[/tex]
With that information, we can substitute [tex]21[/tex] for [tex]x[/tex] in the initial expression:
[tex]11.75(21)[/tex]
Multiply:
[tex]246.75[/tex]
Therefore, if the student worked 21 hours this month, she will earn $246.75.
-
We can check our work by setting the initial expression equal to our solution:
[tex]11.75x=246.75[/tex]
Divide both sides of the equation by the coefficient of [tex]x[/tex], which is [tex]11.75[/tex]:
[tex]x=21[/tex]
Since this quotient matches the number of hours she worked, our solution is correct!

Somebody Please solve this question without using L Hospital rule.
Evaluate if:
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]

Objective: Solve systems of equations with three variables using addition/elimination.
Solving systems of equations with 3 variables is very similar to how we solve systems with two variables. When we had two variables we reduced the system down
to one with only one variable (by substitution or addition). With three variables
we will reduce the system down to one with two variables (usually by addition),
which we can then solve by either addition or substitution.
To reduce from three variables down to two it is very important to keep the work
organized. We will use addition with two equations to eliminate one variable.
This new equation we will call (A). Then we will use a different pair of equations
and use addition to eliminate the same variable. This second new equation we
will call (B). Once we have done this we will have two equations (A) and (B)
with the same two variables that we can solve using either method. This is shown
in the following examples.
Example 1.
3x +2y − z = − 1
− 2x − 2y +3z = 5 We will eliminate y using two different pairs of equations
5x +2y − z = 3
1
3x +2y − z = − 1 Using the first two equations,
− 2x − 2y +3z = 5 Add the first two equations
(A) x +2z = 4 This is equation (A), our first equation
− 2x − 2y +3z = 5 Using the second two equations
5x +2y − z = 3 Add the second two equations
(B) 3x +2z = 8 This is equation (B), our second equation
(A) x +2z = 4 Using (A) and (B) we will solve this system.
(B) 3x +2z = 8 We will solve by addition
− 1(x +2z) =(4)( − 1) Multiply (A) by − 1
− x − 2z = − 4
− x − 2z = − 4 Add to the second equation, unchanged
3x +2z = 8
2x = 4 Solve, divide by 2
2 2
x = 2 We now have x! Plug this into either(A) or(B)
(2) +2z = 4 We plug it into (A),solve this equation,subtract 2
− 2 − 2
2z = 2 Divide by 2
2 2
z = 1 We now have z! Plug this and x into any original equation
3(2) +2y − (1)= − 1 We use the first, multiply 3(2) =6 and combine with − 1
2y + 5= − 1 Solve,subtract 5
− 5 − 5
2y = − 6 Divide by 2
2 2
y = − 3 We now have y!
(2, − 3, 1) Our Solution
As we are solving for x, y, and z we will have an ordered triplet (x, y, z)

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.

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?
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

Which statement for all trapezoids are true? Exactly one pair of opposite sides are parallel Diagonals are always congruent Opposite sides are always congruent
Answer:
Exactly one pair of opposite sides are parallel
Step-by-step explanation:
A trapezoid is a plane shape quadrilateral that has exactly one pair of its sides parallel.
The parallel sides must occur for it to be a trapezoid. If they do not, it is most likely another shape. They could occur between the top and bottom sides while the left and right sides remain non-parallel, or vice-versa.
The other options given do not fall into the description of a trapezoid, as its opposite sides and diagonals are not always congruent.
