start by converting 2 1/4 into a common fraction = 9/4
5/6*9/4=45/24
Here is a graph with the centerline point (0,0) and the nearest min
The function increases at each prime, so the range is [2,4] U [5,6] U [7,8].
9 inches = 3/4 ft
425 ft * 6 ft * 3/4 ft = 425 * 6 * 3/4 = .......... ft3
LJ is cut in half by KM
1/2 LJ = JK
1/2 (45) = 22.5 units
The factor of 2 stretches the graph vertically by a factor of 2
The "3" shifts this upward by 3 units
The distance is 400 km.
Thanks
18 ft = 6 yds
4 ft = (4//3) yd
3 in = (1/12) yd
So
6 ( 4/3) (1/12) = 24 / 36 = 2/3 cu yd
(2/3) (33) = $22
-4x - 15 y = - 17
4x + 5y = -13 add these
A) -10y = -30
B) divide both sides by -10
y = -30 / -10 = 3
C) 4x + 5(3) = -13
D) 4x + 5(3) = -13
4x + 15 = -13
4x = -13 -15
4x = -28
x = -28 / 4 = -7
E) ( -7, 3)
x^2 + 10x + 25 = 8 + 17
x^2 + 10x + 25 = 25 subtract 25 from both sides
x^2 + 10x = 0
x ( x + 10) = 0
x = 0 is the smallest x that makes this true
Do you know where i put the points at on the graph?
8x + 1 = 5 (mod 12)
8x = 4 (mod 12)
2x = 1 (mod 12)
x = 6 (mod 12)
a + m = 18
"All of the above."
is this correct D 2,3
Are you kidding?
A) -3x -2(5x-7) = -12
-3x -10x +14 = -12
-13x = -26
B) x = 2
Use this value of 'x' in one of the equations to find the corrsponding value of 'y'
y = 5x-7
y = 5(2)-7
C) y = 3
D) You HAVE to be able to figure this one out !
a permutation is like you want to select x people from a group of y people
the formula is x*(x-1)*(x-2)*...../y!
(e.g. 4 people from 12 people)
12*11*10*9/4! = 11880/24=495 (ways)
What goes with what question
Welll..... I don't have your graphing tool to use....but it should look like this:
1/4*x=2
multiply both sides by 4 to get x=8
-3x -2(5x-7) = -12
x = 2
y = 3
a solution for this is to know what 10 is a fraction = 20/2
1/2=0.5 so (20+1)/2=21/2
1.25+2+11.5=14.75
14.75-12=2.75
this simplifies to 1/33/1/333
divide to get 333/33 = 10 3/33 = 10 1/11
Thank you so much!!
I have some other questions I need help on can you help???
