The 9 combinations that exist for two movements:
R,R
R,L
R,U *
L,R
L,L
L,U
U,R *
U,L
U,U
Walker would only be able to make it to (1,1) with only 2 of these combinations.
So if he were only allowed to make two movements, his chances of arriving at (1,1) would be 2/9.
Answer:
Step-by-step explanation:
The slope-intercept equation takes the form
Where m is the gradient, and c is the y-intercept.
If we assume we are plotting a graph where the X axis is time, and the y axis is distance, and we know our time value starts at 40, then we can say that our y intercept value is 40.
Next, let's figure out how far she has travelled. 130-40 = 90, and she has travelled this distance in 30 seconds, so dividing 90 by 30, we know that she is travelling 3 feet a second. This leaves us with a gradient of 3.
Putting these two values together, we can find the final form of the equation to be:
The answer is D Tshirts. Unit price means the price of a singular item so to find the unit price of each item you would divide the total price by the amount of items given.
Answer:
Step-by-step explanation:
x = smaller number, y = bigger number
7x + 2y = 635
7y - 2x = 871....rearrange...-2x + 7y = 871
7x + 2y = 635....multiply by 2
-2x + 7y = 871...multiply by 7
----------------------------------
14x + 4y = 1270 (result of multiplying by 2)
-14x + 49y = 6097 (result of multiplying by 7)
--------------------------------add
53y = 7367
y = 7367/53
y = 139
7x + 2y = 635
7x + 2(139) = 635
7x + 278 = 635
7x = 635 - 278
7x = 357
x = 357/7
x = 51
solution : x = 51 and y = 139 or (51,139)
Answer:
Expressions for y:
1. A - 3B
3. A/3 - B
3. (27/13, -60/13)
Step-by-step explanation:
Expressions for y:
A - 3B
A/3 - B
Find combinations to eliminate x
A) 8x + y = 12
B) 2x - 3y = 18
Expressions for y:
A - 3B
A/3 - B
y = 12 - 8x
2x - 3(12 - 8x) = 18
2x + 24x - 36 = 18
26x = 54
x = 54/26 = 27/13
y = 12 - 8(27/13) = -60/13
