Aspeed reader can read 850 words per minute. an average reader can read 1/7 that speed. how many words per minute does an average reader read?

About 121 words per minute or WPM.

Step-by-step explanation:

A reader can read 850 WPM. If an average reader can read 1/7 of that, you divide 850 by 7 to get your answer.

850/7 = 121.42

Then you can round to the nearest tenth to 121.

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2   is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of   numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes.     our only condition is that it passes through the point (-2,5)

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
