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:
v increases when u increases
Step-by-step explanation:
From the question, we have that
Take u = 1
Take u = 2
Take u = 10
<em>This implies that an increment in u brings an increment in v</em>
Rule is : plus 5
Volume is 36
Answer:
Fewer will be sold
Step-by-step explanation: From the start of the graph when the price is high the number sold is low.
Answer:
The angles in the triangle and 10, 80 and 90
Step-by-step explanation:
The two angles that are left in a right triangle add to 90 degrees
8:1 means that there total is 9
8x+1x = 9x
9x = 90
Divide by 9
9x/9 = 90/9
x = 10
8*10 = 80
1*10 = 10
The angles are 80 and 10
The angles in the triangle and 10, 80 and 90
