Which of the following is the correct graph of the solution to the inequality −8 greater than or equal to −5x + 2 > −38? (1 p

Svetlanka [38]

The inequality should read:

$-8 \geq -5x + 2 > -38$

Subtract 2 from all the terms:

$-10 \geq -5x > -40$

Divide all the terms by -5 to get x by itself (note that you flip the inequality signs as you divide by a negative):

$\boxed{2 \leq x < 8}$

The inequality is 2 ≤ x < 8.

A closed dot represents ≤, and an open dot represents <. Since x can represent all values between 2 and 8, you will shade in between 2 and 8 on the number line. x is greater than or equal to 2, so there will be a closed dot on 2. x is less than 8, so there will be an open dot on 8.

The answer is 'number line with a closed dot on 2 and an open dot on 8 and shading in between'.

The sum of the first n consecutive even numbers can be found using S=n2+n, where n≥2. What is the value of n when the sum is 42?

lawyer [7]

Answer:

C. 6

Step-by-step explanation:

<u>Given</u>

S = n² + n
S = 42, n = ?

<u>Substitute and solve for n:</u>

42 = n² + n
n² + 2*1/2n + 1/4 = 42.25
(n + 0.5)² = 42.25
n + 0.5 = √42.25
n + 0.5 = 6.5
n = 6

Correct option is C

Se van a transportar sacos que contienen 50 kg de azúcar cada uno, el camión que se va utilizar para el transporte de los sacos

LekaFEV [45]

Function: $50x=8000$ (maximum number of packages: 160)

Step-by-step explanation:

In this problem, we have:

$C=8 ton = 8000 kg$ is the capacity of the truck (the amount of mass that can be stored in the truck)

p = 50 kg is the mass of each package that need to be stored in the truck

We can find the number of packages that can be transported as follows: calling this number x, the total mass of x packages is

$p\cdot x$

This amount should be at most equal to the capacity of the truck, therefore:

$px=c$

And substituting the numbers,

$50x=8000$

And solving the equation, we can found the number of packages that can fit into the truck:

$x=\frac{8000}{50}=160$

The hocky team won 63 out of 84 games what percent of the games did the team win?

Ronch [10]

Answer:

75%

Step-by-step explanation:

To find how much percent of the team won, you have the event over the sample space.

So n(E)/n(S) = 63/84 = 3/4 = 0.75 = 75%

Feel free to comment if you have any questions! :D

F(x)=x3 −4x even odd or neither

Dennis_Churaev [7]

The answer is neither.

Let's take an odd number and substitute.

f(3) = 3³ - 4(3)
f(3) = 27 - 12
f(3) = 15 (odd)

Now, let's take an even number.

f(4) = 4³ - 4(4)
f(4) = 64 - 16
f(4) = 48 (even)

Since both even and odd numbers are possible, it is neither.
