Answer:
30.1%
Step-by-step explanation:
The increase in price (markup) is ($3.45 - $2.65) = $0.80.
The increase in price (as a decimal fraction) is 0.80/2.65, or 0.301; as a percentate, this is 30.1%
Answer:
Line does not represent direct variation.
Step-by-step explanation:
If the line goes thru the origin, it represents direct variation. Otherwise it does not.
Start by finding the slope of this line:
As we move from (-4,3) to (4,3), x increases by 8 but y does not change. Thus, the slope is 0/8, or just 0. Thus, the equation of this line is y = 3, which does NOT go thru the origin; thus, the points given do NOT represent direct variation.
Answer:
(-4, -1/2)
Step-by-step explanation:
to calculate the midpoints bt of the line use the ormula:

Where (x1, x2) is one coordinate point and (y1, y2) is anither coordinate point. Any two points will work, but I chose A (-5,-4) and B (-3, 3).

(-4, -1/2)
Answer:
138
Step-by-step explanation:
c=5
d=4
6c^2-5d+8
substitute c & d
6(5)^2-5(4)+8
6(25)-20+8
150-20+8 = 138
