Answer:

107

Step-by-step explanation:

The answer would be 107

For the first figure the dimensions of the rectangle is 9 and 8

9x8=72

for the second figure the dimensions are 7 and 5

7x5=35

now we just add them together

35+72=107

therefore 107 is your answer

Polynomials are algebraic expressions represented by variables and coefficients.

<h3>(a) How to determine the interval the open seats increased</h3>

This is the interval, where the open seats increase the same time the time in minutes increases.

From the graph, the open seats increases at the interval (100, 600)

<h3>(b) The time the first meeting ended</h3>

This is the first point where the curve changes its direction from decreasing values to increasing values

From the graph, the curve changes its direction at point (25,100)

Hence, the first meeting ended at 10:25 AM

<h3>(c) When there were 700 open seats</h3>

From the graph, we have:

(x,y) = (5, 700)

Hence, there were 700 open seats at 10:05 AM

<h3>(d) The average rate of change from 10:00 AM to 10:25 AM</h3>

At 10:00 AM, we have:

(x,y) = (0,800)

At 10:25 AM, we have:

(x,y) = (25,100)

So, the average rate of change is:

m = \frac{y_2 -y_1}{x_2 -x_1}

This gives

m = \frac{100 - 800}{25 - 0}

m = \frac{-700}{25 }

m = -28

Hence, the average rate of change from 10:00 AM to 10:25 AM is -28 people per minute

How is Addy 4+ -4 similar to adding 4+4 how is it different use the words and models to explain
Margarita [4]

4- (+) (-4) is similar to 4+4 by the rule of addition in integers that is if Negative + Negative then Add the number and put the sign of greater number.

<h3>What is integer?</h3>

Zero, a positive natural number, or a negative integer denoted by a minus sign are all examples of integers. The inverse additives of the corresponding positive numbers are the negative numbers. An integer, pronounced "IN-tuh-jer," is a whole number that can be positive, negative, or zero and is not a fraction. Integer examples include: -5, 1, 5, 8, 97, and 3,043. 1.43, 1 3/4, 3.14, and other numbers that are not integers are some examples. Three categories of integers exist: Zero (0) (0) Good integers (Natural numbers) Integer Negatives (Additive inverse of Natural Numbers).

The rules of addition in integers says,

- + -  = +

by this,

4-(-4)=8

by concept of addition,

4+4=8
