Answer:

The average rate of change is -3

Step-by-step explanation:

we have

f(x)=-3x+1

This is a linear function in slope intercept form  f(x)=mx+b

where

m is the slope

b is the y-intercept

In this problem

The slope is equal to

m=-3

Remember that

In a linear function the average rate of chance is a constant and is equal to the slope of the linear function in any interval

therefore

The average rate of change is -3

<span>To acquire knowledge, thought is a fundamental necessity -It must be "thought about" before any new ideas can be formulated (e.g., a student who is learning English as a second language must be competent in his primary native language before he can "think" or understand new concepts in another language) -Initial emergence of language and thought are separate from each other, until about the age of 3 when a transition takes place in the child from the external to the internal -Children practice private speech (self-talk) to become more competent ---The use of private speech helps children to self-regulate through organizing, guiding, and controlling their behavior ---Private speech is responsible for all higher levels of mental functioning Noam Chomsky Language Acquisition -Language learning is innate -Chomsky believes that children are prewired to learn language and that infants have a language acquisition device (LAD) built-in neurologically so that they can intuitively understand grammar -There is a critical period when children find it easy to learn language Language development milestones: Infant (0-12 months) -Early vocalizations are spontaneous sounds of cooing (vowels) or crying -Then babbling sounds (phonemes) begin with sounds more like patterned speech with consonant-vowel strings ("da-da-da-da")</span>

Help pls with math lotsss of points!!!

Answer:

5x^2+22x-12         x cannot be -5, -4, -2

(x+5)(x+4)(x+2)

Step-by-step explanation:

In order to solve this, your denominator must be the same. Let's start by writing out the two different quadratic formulas:

x^2 + 6x + 8 <-- This should factor out to (x+4)(x+2)

x^2 + 7x + 10 <-- This should factor out to (x+5)(x+2)

Now that you have factored out the two quadratics, plug them into the equation.

    5x        -       3

(x+4)(x+2)      (x+5)(x+2)

Now as we know, -2 cannot be x because it will turn the entire equation undefined. Multiple top and bottom with (x+5) on the right side and (x+4) on the left side.

5x (x+5)             -           3(x+4)  

(x+5)(x+4)(x+2)      (x+5)(x+4)(x+2)

Focus on the top. 5x(x+5) will turn out to be 5x^2+25x. 3(x+4) will turn out to be 3x+12. Combine the two equations because now they are equal to each other and do the subtraction:

5x^2+25x - (3x+12)     =    5x^2+22x-12         x cannot be -5, -4, -2

 (x+5)(x+4)(x+2)               (x+5)(x+4)(x+2)
