Step-by-step explanation:
It's a little hard to explain, but take the function and put it where the variable is. So, for "A" the equation would be [tex]f(1)=2^1[/tex]
You are walking directly away from your house. You are 5 miles away from your house when you start walking, so you can determine your distance from your house by adding 5 to the number of miles you have walked. In the equation below, x represents the number of miles you have walked, and y represents your distance from home in miles.
The relationship between these two variables can be expressed by the following equation:
y=x+5
Identify the dependent and independent variables.
Answer:
y is the dependent variable and x is the independent variable
Step-by-step explanation
The number on the right of the equal sign is always the independent variable and the number on the left is always the dependent variable.
independent variable = dependent variable +5

Rewrite the equation below so that it does not have fractions.
2 - [tex]\frac{3}{4} x =\frac{9}{10}[/tex]
Answer:
40-15x=18
Step-by-step explanation:
Multiply both sides of 2 - 3/4x = 9/10 by twenty to get
20*2 - 20*3/4*x = 20*9/10
which is 40 - 15x = 18
This should be as far as you need to go, but incase you need to go further,
subtract 40 to both sides
multiply both sides by -1 to get rid of the negatives infront of the x
then divide both sides by 15 to get
x=22/15
and yes, when you solve for x, it is a fraction, but just incase if its needed, I included it. Hope this helps in the future! Let me know if any more questions you have on this problem.

Los vértices de un triángulo en el plano cartesiano son A(-3, 4), B(4, 4) y C(4, -3). ¿Cuál es el área en unidades cuadradas del triángulo?
rapido pllsssss
El área del triángulo es de 24.5 unidades cuadradas.
En este problema, procedemos a resumir el procedimiento como sigue:
1) Calculamos las longitudes de los segmentos de línea AB, BC y AC por medio de la ecuación de longitud del segmento de línea.
2) Determinamos el semiperímetro del triángulo.
3) Determinamos el área del triángulo mediante la fórmula de Herón.
Si tenemos que [tex]A(x,y) = (-3, 4)[/tex], [tex]B(x,y) = (4, 4)[/tex] and [tex]C(x,y) = (4, - 3)[/tex], entonces aplicamos el procedimiento como sigue:
Paso 1 - Longitudes de segmentos línea
Segmento AB
[tex]l_{AB} = \sqrt{[4-(-3)]^{2}+(4-4)^{2}}[/tex]
[tex]l_{AB} = 7[/tex]
Segmento BC
[tex]l_{BC} = \sqrt{(4-4)^{2}+[(-3)-4]^{2}}[/tex]
[tex]l_{BC} = 7[/tex]
Segmento AC
[tex]l_{AC} = \sqrt{[4-(-3)]^{2}+(-3-4)^{2}}[/tex]
[tex]l_{AC} = 7\sqrt{2}[/tex]
Paso 2 - Cálculo del semiparámetro
[tex]s = \frac{l_{AB}+l_{BC}+l_{AC}}{2}[/tex]
[tex]s = \frac{14+7\sqrt{2}}{2}[/tex]
[tex]s = 7 + \frac{7\sqrt{2}}{2}[/tex]
Paso 3 - Cálculo del área del triángulo
[tex]A = \sqrt{s\cdot (s-l_{AB})\cdot (s-l_{BC})\cdot (s-l_{AC})}[/tex]
[tex]A = 24.5[/tex]
El área del triángulo es de 24.5 unidades cuadradas.

Half of the smaller of two consecutive even integers is equal to two more than the larger integer. find both integers Please i will give brainliest ASAP
Answer:
-8 and -6.
Step-by-step explanation:
Let the first even integer be a.
Since the second is a consecutive even integer, it is given by (a + 2).
Half of the smaller (i.e. a) is equal to two more than the larger (i.e. a + 2). In other words:
[tex]\displaystyle \frac{a}{2} = (a + 2) + 2[/tex]
Solve for a:
[tex]\displaystyle \begin{aligned}\displaystyle \frac{a}{2} &= (a + 2) + 2\\ \\ \frac{a}{2} &= a + 4\\ \\ a &= 2a + 8 \\ \\ a &= -8 \end{aligned}[/tex]
In conclusion, the two even, consecutive integers are -8 and -6.

6 in
10 in.
8 in.
18 in.
Answer:
2,304in^3
Step-by-step explanation:
The formula for volume is [ b * l * h ]. We can use the values we are given to find the volume of both rectangles then add them both together.
12 * 12 * 6 = 864in^3
18 * 10 * 8 = 1,440in^3
Add them both together.
864 + 1440 = 2,304in^3

Find the complement of set B in-universe U.
U is the set of natural numbers less than or equal to 8
B is the set of even factors of 8
Answer:
B' = {1, 3, 5, 6, 7}
Step-by-step explanation:
U = {1, 2, 3, 4, 5, 6, 7, 8}
B = {2, 4, 8}
So the complement ( the set of elements in U but not in B) is:
B' = {1, 3, 5, 6, 7}
