Answer:

The answer in each numeral is:

  1. <u>f(4) = 28</u>
  2. <u>f(10) = -19</u>
  3. <u>f(-5) = -33</u>
  4. <u>f(9) = -9</u>

Step-by-step explanation:

To obtain the result in each case, you must replace the variable (n) by the value that appears in the second case, I'll explain it with the first exercise:

  • 1. f(n) = 5n + 8
  •   f(4) = ?

As you can see, in the second doesn't appear f(n), but f(4), that means you must replace the "n" in the equation by 4, if we do this, we obtain:

  • 1. f(4) = 5*(4) + 8
  • f(4) = 20 + 8
  • <u>f(4) = 28</u>

The first answer is 28, now we'll continue with the next exercises:

  • 2. f(n) = -2n + 1
  • f(10) = -2*(10) + 1
  • f(10) = -20 + 1
  • <u>f(10) = -19</u>

  • 3. f(n) = 6n - 3
  • f(-5) = 6*(-5) - 3
  • f(-5) = -30 - 3
  • <u>f(-5) = -33</u>

  • 4. f(n) = -n
  • <u>f(9) = -9</u>

In this form, <u><em>you can prove the answers are: 28, -19, -33, and -9 respectively</em></u>.

Alex73 [517]

Answer:

24 purple jelly beans

Step-by-step explanation:

We are told in the question that;

Lucas had a mix of red and purple jelly beans. There were 2 red jelly beans for every 3 purple jelly beans.

The results in a ratio

2:3

Where 2 represented red jelly beans

3 represented purple jelly beans

Total number of jelly beans = 40 jelly beans.

The number of purple jelly beans that we have =

3/( 2 + 3) × 40

= 3/5 × 40

= 3 × 8

= 24.

Hence, there are 24 purple jelly beans in the bag.

(Angle/triangle problem 25points)<br> What is the value of X?
Serhud [2]

Answer:

x = 5

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

Sum the 3 angles in the triangle and equate to 180, that is

10x - 4 + 8x + 3 + 91 = 180

18x + 90 = 180 ( subtract 90 from both sides )

18x = 90 ( divide both sides by 18 )

x = 5
