PLZ HELP: Write the inverse function for the function, ƒ(x) = 1/2x + 4. Then, find the value of ƒ -1(4). Type your answers in the box.
Answers
Answer:
see explanation
Step-by-step explanation:
let y = f(x) and rearrange making x the subject, that is
y = [tex]\frac{1}{2}[/tex] x + 4 ( multiply through by 2 to clear the fraction )
2y = x + 8 ( subtract 8 from both sides )
2y - 8 = x
Change y back into terms of x with x = [tex]f^{-1}[/tex] (x) , then
[tex]f^{-1}[/tex](x ) = 2x - 8
[tex]f^{-1}[/tex](4) = 2(4) - 8 = 8 - 8 = 0

Answer:
x = 7
Step-by-step explanation:
The larger triangle is twice as big as the smaller triangle. Therefore, the length of the side EF is twice as large as the side YZ.
I multiplied 4.5 (the length of YZ) and 2 to get 9. The value of side EF is 3x-12 and should be equivalent to 9.
3x - 12 = 9
I solved this equation by adding 12 to both sides and dividing 3 on both sides.
The value of x is 7.

Answers
Answer:
60˚, 75˚
Step-by-step explanation:
for part a:
since all sides are the same length (represented by the 3 same type of tick marks on all sides) then the triangle is equilaterial. Which means all the angles are the same.
Sum of angles in a triangle is 180˚.
x represents the value of <N, <M, and <P
so since all angles are the same, 3x = 180, all angles of part a triangle are 60˚. Therefore, <M is 60˚.
for part b:
this is an isoceles triangle since two sides are the same length.
If it's isoceles, that means it's 2 base angles are the same value.
We've already been given the vertex angle.
x represents the value of <S and <Q

You raise pigs. When you purchase the pig it weighs 54 pounds. Within 5 to 6 months your pig will gain around 420% in weight. How much should it weigh by then?
Answers
Answer:
280.8 pounds
Step-by-step explanation:
Original weight of pig = 54 pounds
Percentage increase in weight = 420%
Current weight of pig = original weight + 420% of original weight
= 54 + 420% of 54
= 54 + 420/100 * 54
= 54 + 4.2 * 54
= 54 + 226.8
= 280.8 pounds
Current weight of pig = 280.8 pounds

Step-by-step explanation:
A triangle is 180 degrees.
180 - 85 - 63 = 32 degrees.
Answer:
x = 32
Step-by-step explanation:
All interior angles in a triangle equal to 180
use this to solve for x
180 = 85 + 63 + x
180 - 85 - 63 = x
32 = x

A whole number is 6 more than 2 times another number. The sum of the two numbers is less than 50. This can be written in an inequality as x+2x+6<50, where xrepresents the smaller number.
From the set (13, 14, 15, 16, 17), the values of x for which the inequality holds true are
Answers
Answer:
13, 14
Step-by-step explanation:
The parameters of the numbers are;
A whole number value = 2 × Another number + 6
The sum of the two numbers is less than 50
Given that the first number is equal to more than twice the second number, we have that the first number is the larger number, while the second number is the smaller number
Where 'x' represents the second number, we get;
x + 2·x + 6 < 50
Simplifying gives;
3·x + 6 < 50
x < (50 - 6)/3 = 14.[tex]\overline 6[/tex]
x < 14.[tex]\overline 6[/tex]
Therefore, the numbers for which the inequality holds true are numbers less than 14.[tex]\overline 6[/tex]. From the given option, the numbers are 13, and 14.

Step-by-step explanation:
Population in statistics can be explained as the group or set of all elements which are of particular interest to a researcher or a study. In the scenario above, the research interest concerns customers who pay with a debit card, whose number amounts to 34,000, this value refers to the population. The sample is referred to as the subset of the population or larger sample, the sample from the study corresponds to number of debit card users who were selected at random to participate in the survey. This value is 2000.

¿Cómo expresarías la siguiente cantidad 1149,8x1018, en su equivalencia a notación científica?
Answers
hay tres respuesta creo en el problema te los dire los tres:
Primero tu pregunta:
Cómo corregirías esta equivalencia?
1149,8 x 10¹⁸ = 1,15 x 10¹⁸
Recordemos:
-en la notacion cientifica no se aproxima, solo se reduce
-Requisito: La notacion cientifica debe estar dentro de los estandares de 1-10
sabiendo esp te dare un ejemplo y asi se te hace mas faci:
1149,8 x 10¹⁸ = 1,15 x 10¹⁸ esta es mal
1149,8 x 10¹⁸ = 114,98 x 10¹⁸ + 1 ( esto se suma xq se movio la coma a la derecha)
PSDT: esta sumando el exponente ese pequeño(yo no puedo ponerlo pequeño xd)
Bueno segun esto avanzamos hasta que cumpla el requisito
y quedaria asi:
1149,8 x 10¹⁸ esta es la forma mala
asi quedaria: 1,1498 x 10 sobre 21 ( arribita del 10 va 21)

what is the solution of in(x-2)^2=6
Answers
Answer:
22.09
Step-by-step explanation:
Given the expression ln(x-2)^2=6
Take exponent of both sides
e^ln(x-2)^2=e^6
(x-2)² = e^6
(x-2)² = 403.43
x - 2 = √403.43
x - 2= 20.09
x = 20.09 + 2
x = 22.09
Hence the value of x is 22.09
