Aaliyah is deciding between two parking garages. Garage A charges an initial fee of $8 to park plus $2 per hour. Garage B charges an initial fee of $4 to park plus $3 per hour. Let AA represent the amount Garage A would charge if Aaliyah parks for tt hours, and let BB represent the amount Garage B would charge if Aaliyah parks for tt hours. Graph each function and determine the interval of hours parked, t,t, for which Garage A is cheaper than Garage B.
The interval of hours for which Garage A is cheaper than Garage B is t > 4.
Let A represent the amount Garage A would charge if Aaliyah parks for t hours, and let B represent the amount Garage B would charge if Aaliyah parks for t hours.
Garage A charges an initial fee of $8 to park plus $2 per hour. Hence:
A = 2t + 8
Garage B charges an initial fee of $4 to park plus $3 per hour. Hence:
A = 3t + 4
For Garage A to be cheaper than Garage B:
2t + 8 < 3t + 4
8 - 4 < 3t - 2t
4 < t
t > 4
The interval of hours for which Garage A is cheaper than Garage B is t > 4.

She multiplies the second equation by 2, then subtracts the resulting equation from the first. To her surprise, she gets the equation 0 = 0.
What is special about this system of equations? Why does she get this result and what does it mean about the solutions?
Answer:
If we solve any such equation and get the answer as 0 = 0 so this means that system of equations has infinite solutions.

A line that passes trough the point (7,3) with slope of -1 ( answer plesse I need help )
Answer:
Slope-Intercept Form:
The equation of a line in slope-intercept form is y=mx+b. Since we know that the slope is -1, the equation so far is y=-x+b. To find the value of b, substitute in the given point.
3=-7+b
Add 7 to both sides.
10=b
The equation of the line is slope intercept form is y=-x-10.
Point-Slope Form:
The equation of a line in point-slope form is y-y1=m(x-x1). Substituting in the given point and slope, the equation is y-3=-(x-7).
Hope this helps! :)
Answer:
y= -x + 10
Step-by-step explanation:
3 = -1(7) + b
3 = -7 + b
10 = b
Since the slope is -1, that means it's just -x
So y = -x + 10

Find the median and mean number of hours for these students.
If necessary, round your answers to the nearest tenth.
Step-by-step explanation:
The mean (average) of a data set is found by adding all numbers in the data set and then dividing by the number of values in the set.
The median is the middle value when a data set is ordered from least to greatest.
If there is an even number of items in the data set, then the median is found by taking the mean (average) of the two middlemost numbers.
so, the mean value is
(10+10+18+18+10+5+12+13)/8 = 96/8 = 12
the median is first not clear when ordering the data set, as we have an even number of elements.
5 10 10 10 12 13 18 18
so, we have to take the mean or average between the 2 middle numbers : 10 and 12.
(10+12)/2 = 22/2 = 11
the median is 11.
the perimeter of rectangle is 2x² + 4x - 4y. its length is (2x - 3y). find the breadth of rectangle
plz help fast plz plz
Perimeter = 2 (l + b)
2x² + 4x - 4y = 2 {(2x - 3y) + b}
2x² + 4x - 4y = (4x - 6y) + 2b
2x² + 4x - 4y - (4x - 6y) = 2b
2x² + 4x - 4y - 4x + 6y = 2b
2x² + 2y = 2b
(2x² + 2y)/2 = b
x² + y = b
Breadth = x² + y

In this exercise we have to use the knowledge of polygon areas to calculate the area of each of the informed objects, so we have to:
1) [tex]h = 19.1 in[/tex]
2) [tex]a = 6.7 ft[/tex]
3) [tex]e = 2.3 m[/tex]
4) [tex]y = 9.8 cm[/tex]
5) [tex]o = 71.6 ft[/tex]
6) [tex]e = 15.3 in[/tex]
7) [tex]y = 41.5 m[/tex]
8) [tex]o = 13.7 cm[/tex]
9) [tex]p = 18.5 ft[/tex]
10) [tex]s = 25.8 in[/tex]
11) [tex]b = 61.3 m[/tex]
12) [tex]n = 6.2 cm[/tex]
Then each of the figures will have its own area formula that corresponds to:
1) For the rectangle we find that:
[tex]14/11 = h/15\\h = 19.1 in[/tex]
2) For the rectangle we find that:
[tex]5/a = 9/12\\a = 6.7 ft[/tex]
3)For the rectangle we find that:
[tex]3.7/6.5 = e/4.0\\e = 2.3 m[/tex]
4) For the triangle we find that:
[tex]10/8 = s/13\\s = 16.3 cm\\6/8 = y/13\\y = 9.8 cm[/tex]
5) For the triangle we find that:
[tex]n/70 = 53/88\\n = 42.2 ft\\o/70 = 90/88\\o = 71.6 ft[/tex]
6) For the triangle we find that:
[tex]t/9.1 = 11.2/5.7\\t = 17.9 in\\e/9.1 = 9.6/5.7\\e = 15.3 in[/tex]
7) For the triangle we find that:
[tex]u/48 = 43/74\\u = 27.9 m\\y/48 = 64/74\\y = 41.5 m[/tex]
8) For the triangle we find that:
[tex]6.2/11.8 = t/10.1\\t = 5.3 cm\\o/10.1 = 16.0/11.8\\o = 13.7 cm[/tex]
9) For the triangle we find that:
[tex]30/p = 13/8\\p = 18.5 ft[/tex]
10) For the trapezoid we find that:
[tex]20/s = 12/15.5\\s = 25.8 in[/tex]
11)For the triangle we find that:
[tex]l/46 = 125/75\\l = 76.7 m\\b/46 = 100/75\\b = 61.3 m[/tex]
12)For the triangle we find that:
[tex]5.1/4.3 = r/9.8\\r = 11.6 cm\\n/9.8 = 2.7/4.3\\n = 6.2 cm[/tex]

1428 rounded to the nearest thousandth
Answer:
1428- one is in the thousandth place
the number beside is lower than five so drop it and add zero to the end
1000 -is now your answer
Step-by-step explanation:
hope this helps if not then sorry goodluck and bye
The number 1428 to the nearest thousand is 1000.
When you round a number to a certain digit, you have to check the value of the digit before the place you want to round off to.
1. If the number you are rounding is followed by 5, 6, 7, 8, or 9, round the number up.
2. If the number you are rounding is followed by 0, 1, 2, 3, or 4, round the number down.
Here, the question said the nearest thousand, so I had to look at the value in the hundred places which is 4 and less than 5.
Hence round the number down.
So, 1428 to the nearest thousand is 1000.

AC = BC = 5 cm
∠A = 60°
Step-by-step explanation:
All of the points on a circular arc are the same distance from the center of the arc. This construction makes the radius of each arc be 5 cm, so point C is 5 cm from the arc centers: A and B. That is, ...
AC = 5 cm
BC = 5 cm

We have 5 ft 9 in = 69 in, so
P(X > 69) = P((X - 64.1)/2.5 > (69 - 64.1)/2.5) = P(Z > 1.96)
where X and Z both represent women's heights, but Z is normally distributed with mean 0 and s.d. 1.
Then consulting a table of z-scores, you'll find that P(Z > 1.96) ≈ 0.025. So approximately 2.5% of women are taker than 5'9''.
