Answer:
jhsdfjlh
Step-by-step explanation:
The equation of the line thru <span> (14,5) and (19,15) is found as follows:
15-5 5
slope = m = ----------- = ------ = -1
19-14 5
Thus, the slope of any line perpendicular to this first line has the slope
m = -1/1 = -1.
Then, using the point-slope form, y-15 = -1(x-19), or y -15 = -x + 19, or
y= -x + 34 (answer)</span>
Answer:
40 seconds
Step-by-step explanation:
cheetah: y=90x
antalope: y=60x+120
set them = to each other
90x=60x+120
30x=120
x=40
For the answer to the question above,
since the only variable used to determine earnings is the number of doors knocked, you can eliminate options 1 and 3 as they are based on the number of books sold, which is not a part of the equation.
<span>That leaves the only options being the increase of $20 or $50 for each door knocked. As the x value we multiply by 20, the correct answer is #2, her earnings will increase by $20 for each door knocked. </span>
<span>You can also check this by plugging in values: </span>
<span>Assume 10 doors are knocked: </span>
<span>E(10) = 20(10)-50 = 200-50 = 150 </span>
<span>Assume 11 doors (1 more door) is knocked: </span>
<span>E(11) = 20(11)-50 = 220-50 = 170 </span>
<span>The increase from 1 door is $20.</span>
