Step-by-step explanation:
The following is a list of perfect Cubes
13 = 1
23 = 8
33 = 27
43 = 64
53 = 125
63 = 216
73 = 343
83 = 512
93 = 729
103 = 1000
If a variable with an exponent has an exponent which is divisible by 3 then it is a perfect cube. To get the cube root, we simply divide the exponent by 3. For example x9 is a perfect cube, its cube root is x3 . x11 is not a perfect cube.
The points where a graph crosses the x-and y- axis are called the <u>Origin</u><u>.</u>
Answer:
(-2, 1)
(2, 5)
Please solve the third question and answer in the comments and I will tell you if you are correct.
Step-by-step explanation:
1)Find the solution of the following system of equations; express the answer as a coordinate pair (x,y):
y = x + 3 subtract from the bottom and solve for x
y = -2x - 3
y - y = x - (-2x) + 3 - (-3)
0 = 3x + 6
-6 = 3x
-2 = x
y = x + 3 y = -2 + 3 y = 1 (-2, 1)
2)Find the solution of the following system of equations; express the
answer as a coordinate pair (x,y):
y = 2x + 1 subtract from the bottom and solve for x
y = x/2 + 4
y-y = 2x - 1/2 x +1 - 4
0 = x(2-1/2) - 3
3 = 1.5x
2 = x y = 2x + 1 y = 2(2) + 1 y = 5 (2, 5)
3) Find the solution of the following system of equations; express the
answer as a coordinate pair (x,y):
y = -3x + 6 subtract from the bottom and solve for x
y= -1/2x+1
y-y = x(-3 - (-1/2)) + (6 - 1) follow the examples above
Answer:
a)12
b)1/12
c)4/12
Step-by-step explanation:
a) the coin is a 1/2 and the dice is 1/6 so you times the bottom number and you get 12
b) since that is a exact one way to get it has to be 1/12 chance
c) so to only get a tails it would be 6/12 and less than 5 means you can get 1,2,3, and 4 so that is 4 ways out of 12 ways so its 4/12
The answer to your question is (1,9) :)
