Answer:
B - 9
Step-by-step explanation:
5 x 9 = 45 or 45 divided 5
y = x + 5
If it's perpendicular the slope is the opposite inverse of the other line,
The slope of line y = x + 5 is 1, because it's the number before x, so, the opposite inverse would be -1/1 = -1.
Answer:
1.5 cm/s
Step-by-step explanation:
The unit rate is the same as the slope.
To find the slope, we use the slope formula:

Using our points, we have
m = (9-0)/(6-0) = 9/6 = 3/2 = 1.5 cm/s
Answer:
p = 2.7x - 20
p(90) = $223
Step-by-step explanation:
revenue → f(x) = 3x ,where x is the number of downloads.
the statement “Your profit p is $20 less than 90% of the revenue for x downloads”
<u><em>means</em></u>

………………………………
the profit for 90 downloads :
= p(90)
= 2.7×(90) - 20
= $223
