Answer:

(-4, 24)

(-2, 18)

(0, 12)

(2, 6)

(4, 0)

Step-by-step explanation:

You need to plug the domain values into the function for x to find the range, which is the y.

f(x) = 12-3x

So for -4, it would be f(-4) = 12 - 3(-4) = 24, and do the same with the other values.

On the subway 8 out of 11 people are carrying a briefcase.Based on this information, if there are 700 people on the subway, then

Answer:

191 people do not have a briefcase

Step-by-step explanation:

Proportion states that the two ratios or fraction are equal

As per the given condition:

On the subway 8 out of 11 people are carrying a briefcase.

⇒Total number of people = 11

and number of people carrying a briefcase = 8

Remaining number of people that do not carrying a briefcase = 11-8 = 3

Now,

Based on this information, if there are 700 people on the subway

Let x be the number of people do not have a briefcase

By definition of proportion :

$\frac{3}{11} = \frac{x}{700}$

Multiply 700 both sides, we have

$\frac{3}{11} \times 700 = x$

Simplify:

x = 190.90≈ 191

Therefore, 191 people do not have a briefcase

What is negative 3 minus x equals negative 10

OlgaM077 [116]

In order to solve this equation, let's write it out in number form:

-3 - x = -10

In order to isolate 'x' we need to ensure that there is only 'x' on one side. We can get rid of the -3 by adding 3 to both sides:
-3 + 3 - x = -10 +3
-x = -7

Because there are negatives on both sides, you can simply cancel them out:

x = 7

Answer:

Step-by-step explanation:

In the 3rd question, we are given the equation x ^ 3 + x ^ 2 + 2x + 24. One of the factors is x + 3. Now, we can use long division to find that the equation we have left is x^2 - 2x - 8. We can just factor this to get (x - 4) (x + 2). In the 3rd question, possible factors for the coefficient are 1, 2, -1, -2. Possible factors for the constant are 1, 7, -1, -7. Now, we can try out all of them. The possible factors are 1, 7, -1, -7, 2, 14, -2, -14.
