Given that f(x) = 2x + 1
Find f^-1(x)
Answer:
f-¹(x) = (x-1)/2
Step-by-step explanation:
switch the x and y then solve for y
x= 2y +1
x- 1 = 2y
y = (x-1)/2
Answer:
[tex]F^{-1}[/tex] (x) = [tex]\frac{x}{2}[/tex] - [tex]\frac{1}{2}[/tex]
Hope this helped!
plz will mark as brainliest
Answer:
30
Step-by-step explanation:
1/2 x (a+b) x h = area
1/2 x ( 40 + x ) x 50 = 1750
1/2 (40 + x )= 1750/50
20 + 1/2x = 35
1/2 x = 35 - 20
x = 15 x 2
= 30
I hope this is right :)

PLEASE GIVE ME BRAINLIEST AND THANK YOU FOR THIS CHALLENGE VERY EASY TO DO.
Answer:
-9,4.5,90
Step-by-step explanation:
9) [tex]\frac{12xy}{x-y}[/tex]
So you basically substitute the values in for x and y which give you
[tex]\frac{12(3)(-1)}{3-(-1)}[/tex]
[tex]\frac{12(-3)}{3+1}[/tex]
[tex]\frac{-36}{4} \\-9[/tex]
10) Same thing:
[tex]\frac{4xy}{2x} \\\\\frac{4(3)(9)}{2(3)} \\\\\frac{4(27)}{6} \\\\4.5[/tex]
11) Same for this:
[tex]\frac{2}{3}(9x+xy)\\\\ \frac{2}{3}(9(5)(3)\\\\\frac{2}{3}( 135)\\[/tex]
3*45=135
[tex]2(45)\\90[/tex]
Based on this information, I want you to figure out the last one. If you need help reply to this answer and I will respond.
is y=6x+3 proportional or nonproportional
Answer:
f the x and y coordinates form proportional relationships, then there is some non-changing number (a constant) that when multiplied times x will create y

All students in Ridgewood Junior High School either get their lunch in the school cafeteria or brought it from home on Tuesday. 5% of students brought their lunch. 36 students brought their lunch. How many students in total are in Ridgewood Junior High School?
Answer: 720
Step-by-step explanation:
5%=36
1%=36/5
1%=7.2
100%=7.2*100
100%=720 students
There is a total of 720 students are in Ridgewood Junior High School.
Given,
All students in Ridgewood Junior High School either get their lunch in the school cafeteria or brought it from home on Tuesday.
5% of students brought their lunch.
36 students brought their lunch.
To determine how many students in total are in Ridgewood Junior High School.
the percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.
Let there be x students in the Ridgewood Junior High School.
5% of students brought their lunch and equal to 36
so 5% of x = 36
5/100 * x = 36
x = 36*100/5
x = 36*20
x = 720
Thus, there is a total of 720 students are in Ridgewood Junior High School.

What is the total cost of a $12 t-shirt if the sales tax is 6.5%?
Answer:
The answer is $12.78
Step-by-step explanation:
Answer:
So if you want to find 6% sales tax for an item costing $12, simply move the decimal point to the left two places and multiply. You will write 6% as . o6. Now multiply that by 12 to find the sales tax.
Step-by-step explanation:
Calculating Total Cost. Multiply the cost of an item or service by the sales tax in order to find out the total cost. The equation looks like this: Item or service cost x sales tax (in decimal form) = total sales tax. Add the total sales tax to the Item or service cost to get your total cost.
Calculating sales tax on a product or service is straightforward: Simply multiply the cost of the product or service by the tax rate. For example, if you operate your business in a state with a 6% sales tax and you sell chairs for $100 each, you would multiply $100 by 6%, which equals $6, the total amount of sales tax.
A circle has circumference 33.9 cm. What is the area of the circle? Use 3.14 for .
The area of the circle is about cm?
(Round the final answer to the nearest whole number as needed. Round all intermediate values to the nearest thousandth as needed.)
Answer:
The area is 902[tex]cm^{2}[/tex]
Step-by-step explanation:
[tex](\frac{33.9}{2})^{2}[/tex] * 3.14
= [tex]16.95^{2}[/tex] * 3.14
= 287.303 * 3.14
≈ 902[tex]cm^{2}[/tex]

Answer:
Step-by-step explanation:
The end behavior of a function describes the behavior of the graph of the function at the "ends" of the x-axis.
The given function is ⇒⇒⇒ f(x) = 2x³ – 26x – 24
the given equation has an odd degree = 3,
and a positive leading coefficient = +2
So, the end behavior of the given function
f(x) → +∞ as x→+∞
f(x) → -∞ as x→-∞

given that ABCD is a parallelogram, find each of the following
AB
AD
< A
< D
Answer:
AB = 8
AD = 10
<A = 118
<D = 62
Step-by-step explanation:
1. AB
Because opposite sides in a parallelogram are equal, DC = AB = 8.
2. AD
Because opposite sides in a parallelogram are equal, BC = AD = 10.
3. <A
Adjacent angles are supplementary in a parallelogram, so A = 180 - 62 = 118
4. <D
Opposite angles are equal in a parallelogram, so B = D = 62
Answer:
AB = 8
AD = 10
m∠A = 28°
m∠D = 62°
Step-by-step explanation:
A few facts to remember about a parallelogram.
1. Opposites sides are congruent
2. Opposites angles are congruent
3. Consecutive angles are complementary
So, AB = 8, AD = 10, m∠A = 90 - 62 = 28°, m∠D = 62°
30 coins consisting of quarters and dimes, which total is $5.70. How
many quarters does she have?
Answer:
18 quarters
Step-by-step explanation:
Answer:
18 quarters 12 dimes
18 x 25 = 450
12 x 10 = 120
18 + 12 = 30
450 + 120 = 570
Therefore, there are 18 quarters.

A large concrete block is used for the cornerstone
of a building. The block is 19 ft deep, 19 ft wide,
and 14 ft long. What volume of concrete is
needed to make this block?
Answer:
The volume of the concrete needed to make the block is 5054 ft³
Step-by-step explanation:
The question relate to the calculation of the volume of a shape
The dimensions of the block are;
The depth of the block, d = 19 ft.
The width of the block, w = 19 ft.
The length of the block, l = 14 ft.
The volume of a cube, V = Length, l × Width, w × Depth, d
Therefore, the volume, 'V' of a cubic block is given as follows;
V = l × w × d = 14 ft. × 19 ft. × 19 ft. = 5054 ft.³
The volume of the concrete needed to make the block = The volume of the block, V = 5054 ft³.

Answer:
b. SAS
Step-by-step explanation:
These triangles can be proven congruent through SAS, or side, angle, side. SAS is used when two sides and one included angle are congruent. For an angle to be included, it must be in between the other two sides. This means the angle's rays are the congruent sides. If two lines have an equal number of tick marks, or if two angles have an equal number of arcs, then they are congruent. In this image, two line pairs are marked as congruent as well as the included angle. Therefore, the correct answer is B. SAS.
