The domain of the function exists for when x ≤ 2 while the range exists for the value of y >0
For f⁻¹(x), the domain and the range exists on all real values
Given the expression
f(x)=√−2x+4
Get the inverse of the function f⁻¹(x)
ley u = f(x)
y = √−2x+4
Replace x as y
x = √−2y+4
Make y the subject of the formula
x² = -2y + 4
-2y = x²-4
y = (x²-4)/-2
Hence f⁻¹(x)= (x²-4)/-2
For f(x), the domain of the function exists for when x ≤ 2 while the range exists for the value of y >0
For f⁻¹(x), the domain and the range exists on all real values

Answer:
see attached
Step-by-step explanation:
In general, the only way to divide a square array of dots into two triangular arrays of dots is the way it was done in the example shown in the problem statement. The dividing line is drawn next to the longest diagonal.
So, for 25 dots, you make a 5×5 array and draw the line next to the corner-to-corner diagonal. Same for a 6×6 array of 36 dots.

Suppose PQ has one endpoint at
P(0, 0). If (2,5) is the midpoint of PQ, what are the
coordinates of point Q?
Step-by-step explanation:
The midpoint can be found with the formula.
midpoint = (x1+x2) /2 , (y1 + y2 )/2
( x1 , y1), and (x2 , y2 ) are the coordinates of two points, and the midpoint is a point lying equidistant and between these two points.
P = (0,0)
midpoint = (2,5)
x midpoint = 2 = (0+ x2)/2
×2 = 4
y midpoint = 5 = (y2+0 )/2
10 = y2
so the point Q is (4 , 10)
How many Christmas trees were sold on sat and sunday?
Hello :D
Let's form an equation:
x/5 = 27
Let's form another equation:
(x+y)/7 = 34
Rearrange equation one so it is x = 27 x 5 = 135
Now we can substitute this value into equation 2:
(135 + y)/7 = 34
135 + y = 238
y = 238 - 135
y = 103
Answer is 103
Answer:
103 christmas trees.
Step-by-step explanation:
total trees sold in the first five days:
[tex]27 \times 5 = 135[/tex]
total trees sold in this week:
[tex]34 \times 7 = 238[/tex]
The answer is:
[tex]238 - 135 = 103[/tex]
QUICKKK I NEED HELP!!!!!!!!!!!!
Answer:
A = -8
B = 27
X = 6
y = 3
z = 9
Step-by-step explanation:
hope that helps
Answer:
Below in bold.
Step-by-step explanation:
A = (-2)^3 = -8.
B = (3)^3 = 27.
j^(3*3) = j^9 and j^(1*3) = j^3
j^9 / j^3 = j^6
So x = 6.
y = 3.
m^(3 * 3) = m^9.
z = 3*3 = 9.

Find the slope of the line whose equation is 8 y = 4 − 3 x .
Answer:
-3/8
Step-by-step explanation:
8y = 4 - 3x
~Divide 8 to everything
y = 1/2 - 3/8x
~Reorder
y = -3/8x + 1/2
In slope intercept form [ y = mx + b ] m resembles the slope so -3/8 is the slope.

two members have a sum of 112. If one number is x, represent the other numbers as an expression in x
Based on the information given, the other number will be 112 - x
Value of the first number = x
Value of the second number = y
Sum of the numbers = 112
Therefore, the value of the second number will be:
x + y = 112
y = 112 - x
In conclusion, the value of the second number is 112 - x.

Kiara desea contratar el servicio de una línea telefónica con internet para realizar sus clases virtuales. Si el costo de una línea de telefonía móvil con Internet es C = 10 + 1,5t (C, en soles; t, en horas).
- Expresa el costo de la línea telefónica móvil en función del tiempo.
- Determina el dominio y el rango de una función.
- ¿Cuál será el costo luego de 48 horas de consumo de la línea telefónica con Internet?
Doy coronita
a) Kiara ha adquirido una línea de telefonía móvil con internet a un Coste Fijo de 10 soles y un Tasa de Consumo de 1,5 soles por hora consumida.
b) El Coste total por 48 horas de consumo de la línea telefónica con internet es 82 soles.
a) Nota - Puesto que la ecuación que describe el Coste ya existe en el enunciado, entonces se entiende el verbo "Expresa" como "Describa en sus propias palabras".
Como puede apreciarse el Coste de la línea telefónica móvil aumenta linealmente con el Tiempo de consumo por parte del usuario. En consecuencia, la función de Coste queda definida como sigue:
[tex]C(t) = C_{o} + r\cdot t[/tex] (1)
Donde:
[tex]C_{o}[/tex] - Coste fijo, en soles.[tex]r[/tex] - Tasa de consumo, en soles por hora.Entonces, tenemos que Kiara ha adquirido una línea de telefonía móvil con internet a un Coste Fijo de 10 soles y un Tasa de Consumo de 1,5 soles por hora consumida.
b) Una característica de las Funciones Lineales es que tanto su Dominio como Rango comprenden al Conjunto de todos los Números Reales, al ser de Pendiente constante esta Función.
Por tanto, el Dominio y el Rango de la Función en cuestión es el Conjunto de todos los Números Reales.
c) Si sabemos que [tex]C_{o} = 10[/tex], [tex]r = 1,5[/tex] y [tex]t = 48[/tex], entonces el Coste Total por concepto de 48 horas de consumo es:
[tex]C(48) = 10 + 1,5\cdot (48)[/tex]
[tex]C(48) = 82[/tex]
El Coste total por 48 horas de consumo de la línea telefónica con internet es 82 soles.
