Answer 2
Answer:

{16y}^(2) + 40y + 25

Step-by-step explanation:

(4y−5)^2+80y

Use binomial theorem (a−b)^2=a^2−2ab+b^2 to expand (4y−5)^2.

16y^2−40y+25+80y

Combine −40y and 80y to get 40y.

16y^2+40y+25

Determine the slope of the line in the graph

Answers

Answer:

4 and -2

Step-by-step explanation:

Answer:

1/2

Step-by-step explanation:

the slope = rise /run

Look at the graph to find 2 points that are easy to read for example (0, -2) and (4, 0).

How did you got from (0, -2 ) to (4, 0) by rising 2 and run 4 so your slope is

Answer:  f(g(-1)) = -16

Step-by-step explanation:

First, we need to find g(−1), which means we substitute -1 in place of x in the function g(x):

g(-1) = 3(-1) = -3

Next, we substitute g(-1) into f(x):

f(g(-1)) = f(-3) = 3(-3) - 7 = -16

Therefore, f(g(-1)) = -16.

In at least 100 words independently write your response to the statement, "Anyone can do well in math."

Answers

Answer:

I believe that this is true. Anyone can do well in math, not everyone. The main difference being that if EVERYone could, that means every one person in the world, no matter the circumstance, so by saying ANYone, it's saying that however many people in the world want to do it, can do it, if they try and put in the work. Math is not biased against any one person, nor is it  favored for any one person. Any person who studies, or learns it can do well in math. Someone who has never learned anything about math will not do well at all. So, yes, ANYone can do well, but not EVERYone.

Not 100 words, but should do trick if you just add in some extra words between phrases, and substitute some words with one or two synonyms.
