Answer:
-(2/3) + (2/3)i
Step-by-step explanation:
( -4 - 4i) / 6i
multply by i/i
(-4i - 4i^2) / 6i^2
since i^2 = -1
(-4i + 4) / -6
(4 - 4i) / -6
Reduce fraction

Answer:
178
Step-by-step explanation:
All right!!
Line l is parellel to line m.
So if r is 91 then we can infer that s helps it make a 180 degree angle/straight line.
So 180 - 91 = 89
s = 89
If the two lines are parallel then s = u because of inner angles/outer angles stuff.
If s=u then u = 89 as well.
And because of vertical angles, t =u so t = 89.
Now the question asks to find t + u, so t + u = 89 + 89 = 178
Hope that helps!!
To mail a letter to Vienna, Austria the post office charges a flat rate of $8.00 and an additional $0.50 for every ounce the letter weighs. The cost of mailing a letter is determined by the equation y=0.50x+8.00, where y is the cost of the postage and x is the weight of the letter in ounces.
Step 2 of 2 : Use the graph to estimate to the nearest quarter of a dollar ($0.25) the cost to send a letter that weighs 3 ounces.
Answer:
It will cost 38 quarters
Step-by-step explanation:
y = 0.50x + 8.00
y = 0.5(3) + 8.00
y = 1.5 + 8.00
y = $9.50
$9.50/.25
38 quarters

sara buys two bags of chips and three boxes of pretzels for $ 85. He then buys another bag of chips and two more boxes of pretzels for $ 50. Find the cost of each bag of chips and each box of pretzels.
Answer:
Chips= $20 Pretzel=$15
Step-by-step explanation:
Sara bought 2 Chips + 3 Pretzels = $85
(Extra) 1 Chips + 2 Pretzels = $50
Pretzels are twice as much as chips so above ^^ Can be expressed
as Pretzel (15) + Pretzel (15) + Chips(20) = $50
Now lets go back to the first line Putting in the new prices
Chips(20) + Chips(20) + Pretzel(15) + Pretzel(15) = Pretzel(15) = $85

A rectangular photograph has an area of 48 square inches. If the width of the photograph is 8 inches less than its height, find the dimensions of the photograph
The height of the photograph is
Answer:
H= 12, W=4
Step-by-step explanation:
let H = height
let H-8 = width
We know that the area of the rectangle is A = H*W
now we substitute the statements we have made:
H(H-8) = 48
H^2 - 8H - 48 = 0
Simplify:
(H-12)(H+4) = 0
So now we have 2 options H = -4 or H = 12, having a -ve number as height does not make sense so we use 12.
We know that width is H-8 so now we do 12-8 which is 4.
Therefore width is 4 and height is 12.

8.5x-y= 16
O -y= 5x + 16
O x=5y-16
O y= 5x +16
O y= 5x- 16
Answer:
y = 5x - 16
Step-by-step explanation:
1. To solve this question, we must convert 5x - y = 16 into slope-intercept form (y = mx + b).
2. (Solving for y)
Step 1: Subtract 5x from both sides.
[tex]5x - y - 5x = 16 - 5x[/tex] [tex]-y = -5x +16[/tex]Step 2: Divide both sides by -1.
[tex]\frac{-y}{-1} =\frac{-5x+16}{-1}[/tex] [tex]y = 5x - 16[/tex]Therefore, the answer is y = 5x - 16.
