Discontinuities can be recognized by observing at
asymptotes. An asymptote is a line where the space between the
curve and the line go to zero as single or both of the x or y coordinates inclines
to infinity. Graphically, they're holes in the graph. Zeroes are points wherever
the graph hits the x axis.
Answer: <u>y = -(1/2)x + 3</u>
<u></u>
Step-by-step explanation:
<u>y = 2x - 1</u>
This is in the format of y=mx + b, where m is the slope and b is the y-intercept (the value of y when x=0).
Perpendicular lines have a slope that is the negative inverse of the reference line. The slope of this reference line is 2, so the slope of a perpendicular kline will be -(1/2).
This yields the equation y = -(1/2)x + b
To find the value of b, we can use the given point, (0,3) and use these values of x and y to solve for b:
y = -(1/2)x + b
3 = -(1/2)(0) + b
b = 3
The equation of a line perpendicular to y = 2x - 1 and goes through point (0,3) is:
y = -(1/2)x + 3
Answer: B
Step-by-step explanation:
If you divide the word by minutes for each one you get 216 which is for the record speed and if you divided how fast Charlie typed it would be 140 which mean that Charlie types slower then the record speed
