Answer:
$2.20
Step-by-step explanation:
Original price (before discount and before tax): $5
Discount is 60%.
Amount of discount is: 60% of $5 = 0.6 × $5 = $3
Price after 60% discount: $5 - $3 = $2
Tax is 10%.
Amount of tax is: 10% of $2 = 0.1 × $2 = $0.20
Final price = price after discount + tax = $2.00 + $0.20 = $2.20
Answer:
the first one, 64(-1/2)^(n-1)
Step-by-step explanation:
To go from one number to the next, we first start with 64, so everything is multiplied by that. Next, 64 turns into -32, and (-32)/64 = -1/2. Similarly, 16/-32 is -1/2, and -8/16 is -1/2 as well. Therefore, we have to multiply each number by -1/2 a number of times. For example, to get from 64 to 16, we have to multiply 64 by negative one half 2 times. The only option with -1/2 in the multiplier is the first one, making that our answer

This may be one of those questions that could take
more paper to ask than to answer.
Line-1 goes through (-4, 8) and (4,6) .
Its slope is (difference in 'y') / (difference in 'x')
Dif in 'y' = (6 - 8) = 2
Dif in 'x' = (4 - -4) = 8
Slope of Line-1 = 2/8 or 1/4
Line-2 goes through (-1, 1) and (3, 5)
Its slope is (difference in 'y') / (difference in 'x')
Dif in 'y' = (5 - 1) = 4
Dif in 'x' = (3 - -1) = 4
Slope of Line-2 = 4/4 = 1
Slope of Line-1 = 1/4
Slope of Line-2 = 4
The slopes of the lines are different.
They can't be parallel, and they can't be the same line.
They must intersect in one point, and only one point.
That means the pair of equations has exactly one (1) solution.
