Hola alguien puede ayudarme a resolver estos ejercicios por favor Ejercicios de intervalos 1.- Escribe en todas las formas posibles los siguientes intervalos y semirrectas: a) { x / –2 ≤ x < 3} b) Números mayores que –1 c) (–[infinity], –5] d) Números mayores o iguales que –7 y menores que 19. e) Números mayores que 9 y menores que 5.

Answers

Answer:

Tenemos 3 formas de escribir cada intervalo, una es con solo texto, la otra es usando los símbolos { <, >, ≤, ≥ }, y la última es con intervalos, donde:

( se usa para " < x "

) se usa para " > x "

[ se usa para  " ≤ x "

] se usa para   " ≥ x "

a) -2 ≤ x ≤3

Esto se escribe como:

"números mayores o iguales que -2 y menores o iguales que 3"

y

[-2, 3]

b) Números mayores que –1

Las otras formas de escribir esto son:

-1 < x

y no tenemos limite mayor, entonces:

(-1, ∞)

con -∞ y ∞ siempre se usan los símbolos ( o )  

c) (–[infinity], –5]  

Las otras notaciones son:

"Un numero menor o igual que -5"

x ≤ -5

d)  Números mayores o iguales que –7 y menores que 19

Las otras notaciones son:

-7 ≤ x < 19

[-7, 19)

e) Números mayores que 9 y menores que 5.

Las otras formas de escribir esto son:

5 < x < 9

whats her errors and whats the soulution​

Answers

Answer:

she messed up at -17=34x

Step-by-step explanation:

she added 8x to each side but she was actually supposed to subtract

The error is 8(x - 3) + 7 = 2x(13) and -17 = 34x.

4 - 17 = -13, not 13

8x - 17 = 26x

-17 = 26x -8

-17 = 18x ( it should be like this, but this is still wrong because it should -26)

The solution is:

8(x - 3) + 7 = 2x(4 - 17)

8(x - 3) + 7 = 2x(-13)

8x - 24 + 7 = -26x

8x - 17 = -26x

8x + 26x = 17

34x = 17

x = 17/34

x = 1/2

Hope it helps!

Question 2
Evaluate the following function:
f(x) = 7x2 + 8x + 20 for f(2)
type the numerical value for your answer

Answers

Answer:

64

Step-by-step explanation:

We have the function f(x) 7x^2 + 8x + 20 and are asked to solve it.

Since we know that x equals 2. We can substitute 2 for every x in the expression.

7(2)^2 + 8(2) + 20

First do the exponent :

2^2

4

7(4) + 8(2) + 20

Multiply 7(4) and 8(2) :

7(4)

28

8(2)

16

28 + 16 + 20

At the end of the summer, I decide to drain the swimming pool

that it was draining at a rate of 1% every minute.
How long will it take to empty the pool?

F 2x + 2x + 3 = 90
G 2(x + 3) = 90
H x(x + 3) = 90
J 2(x) + 2(x + 3) = 90

Answers

Answer:

2(x) + 2(x + 3) = 90

Step-by-step explanation:

Width: x inch.

Marion is driving between two towns that are close together. If she drives 1/5 the distance of the trip in 15 minutes, what is her rate per hour?

Answers

Answer: 75 minutes per hour.

Step-by-step explanation:

From the question, we are informed that Marion is driving between two towns that are close together and that she drives 1/5 the distance of the trip in 15 minutes.

The rate per hour will then be:

= 15 ÷ 1/5

= 15 × 5

= 75 minutes

The rate per hour will then be 75 minutes per hour.
