Answer: -17/28

Step-by-step explanation:

This is very easy.

We read f(x) as "a function of x"

Think of it as a machine. It takes in x, and gives us f(x) after doing some things to it.

f(x) = (x) × 4/7 + 9/4 ,

f(-5) = (-5) × 4/7 + 9/4

Let's work this out now!

= (-5) × 4/7 + 9/4

= -20/7 + 9/4

Now make into 1 fraction with common denominator

= -80/28 + 63/28

= -17/28

(Need 3 answers) An entomologist discovered a new insect species. The population of the insect species can be modeled by P(n) =

Strike441 [17]

Answer:

See below

Step-by-step explanation:

According to the model, the equation is:

P(n) = 3450*bⁿ

Based on the equation, the initial number of insects is 3450

If b = 1.75, daily growth rate is:

1.75 - 1 = 0.75 = 75%

If we get P(4) = 55200, find the value of b:

55200 = 3450*b⁴
b⁴ = 55200/3450
b⁴ = 16
b⁴ = 2⁴
b = 2

umka2103 [35]

Answer:

x=14

Step-by-step explanation:

1. 4x-24+2=6x-6 Break the parenthesis (distributive property)

2. 4x-22=6x-6 Combine like terms

3. 22=2x-6 Minus 4x to each side

4. 28=2x Add 6 to each side

5. 14=x Divide each side by 2
