Can you help me answer this? The phrase miles per hour is an example of a rate of change. What other rates of change commonly used in everyday speech can you think of?

If line a has a greater slope than line b, is line a steeper than line b? Explain, giving examples to support your answer.

Which form of a linear equation do you prefer to use: slope-intercept form or point-slope form? List advantages and disadvantages of each. Compare your answer with a classmate's and discuss any differences.

There is a geometric theorem that says "If two lines in a plane are perpendicular to the same line, they are parallel to each other." Explain why this is true by writing and comparing equations for two different lines that are perpendicular to

add all the numbers and check the ones place.

the answer is 486. as the ones place is more than 4, the estimation will be the next 10 ie, 490

the answer

b. they are parallel and will never intersect.

2/3x + 7 = 29

step-by-step explanation:

two thirds = 2/3

plus a number = x

at least 29 = 29

there for you should get 2/3x + 7 = 29

the answer is; biodiversity resulting from few ancestors

adaptive radiation occurs when a population is subjected to a large natural environment with spatial ecological variations. the parts of the population in the different ecologies begin to adapt to their local environments. due to non-random mating across the large populations, this causes the different populations from the large population to speciate within their local environments. they, therefore, diverge to different species sharing a common ancestor.
