Answer:
A. $0.99p
B. $0.99(8) = $7.92
Step-by-step explanation:
To show that you multiply the unit price by the amount, we can use the variable p. Now, this equation shows that you multiply the price per one pound by the amount of pounds.
If you want to find the cost of 8 pounds, you just put the 8 in place of the p to represent how many pounds. Now, you just need to multiply 0.99 x 8, which equals $7.92.
Answer:
x = 2 ± 2 sqrt(5)i
Step-by-step explanation:
(x – 2)^2 + 20 = 0
Subtract 20 from each side
(x – 2)^2 + 20 -20=0 -20
(x – 2)^2 =- 20
Take the square root of each side
sqrt((x – 2)^2) =±sqrt(- 20)
x-2 = ±sqrt(- 20)
We know sqrt(ab) = sqrt(a) sqrt(b)
x-2 = ±sqrt(- 1) sqrt(20)
We know the sqrt (-1) = i
x-2 = ±i sqrt(4*5)
x-2 = ±i sqrt(4) sqrt(5)
Add 2 to each side
x-2+2 = 2 ±i sqrt(4) sqrt(5)
x = 2 ±i 2 sqrt(5)
x = 2 ± 2 sqrt(5)i
Answer:
Step-by-step explanation: Use the two points that are given to you and substitute them into the slope formula to find the answer.
m=<u><em>y2-y1/x2-x1</em></u>
m=9-5/3-1
m=4/2
Simplify the answer.
m=4/2
m=2/1
Final answer is 2.
The slope is positive meaning it is ascending (going up).

Answer:
108 degrees.
Step-by-step explanation:
2x + 16 = 3x - 12 (corresponding angles; AB parallel to CD).
16 + 12 = 3x - 2x
x = 28.
So the angle marked 3x - 12 = 3(28) - 12
= 72 degrees.
Angle y is adjacent to the angle so
y = 180 - 72
= 108 degrees.
Answer is C).
One way to find the answer is to multiply the $54 by .30 (which is 30%converted to a decimal). Doing this will give you what 30% of $54 is.
This gives you 16.2
Since the question is asking what 30% off the price is, subtract the 16.2 from the $54.
