This would be the same as the last question you posted!
Answer:
Step-by-step explanation:
The mode is the number of most repeated data in the set.
Given set 2, 1, 4, 7, 1 has mode 1 (repeated twice).
If we add 1 to the set the mode will remain 1 as it will repeat three times, so the mode won't change.
There is no change in mode, so the mode decrease is zero.
Answer:
3, -8
(x is equal to 3 and y is equal to -8)
Step-by-step explanation:
<u>The system:</u>
{ 7x=-67-11y
{ 5x=-73-11y
<u>Finding a value for x:</u>
7x=-67-11y -> x = -
<u>Solving for y by plugging in our x:</u>
[Equation] 5x = -73 -11y
[Plug-in] 5( - ) = -73 -11y
[Distribute the 5] - = -73 -11y
[Multiply by 7] 7 ( - ) = (-73 -11y) 7
[Simplify] -335 - 55y = -511 - 77y
[Add 335 and 77y to both sides] 22y = -176
[Divide by 22] y = -8
<u>Plug in our y to solve for x:</u>
5x = -73 -11y
5x = -73 -11(-8)
5x = -73 + 88
5x = 15
x = 3
Have a nice day!
I hope this is what you are looking for, but if not - comment! I will edit and update my answer accordingly. (ノ^∇^)

You would do 120 mins divides by 15 miles = 8
1 mile = 8 mins
6 x 8 = 48 mins
Y = mx + b
slope(m) = -5/2
(-4,4)...x = -4 and y = 4
now we sub and find b, the y int
4 = -5/2(-4) + b
4 = 10 + b
4 - 10 = b
-6 = b
so ur equation is : y = -5/2x - 6....or 5x + 2y = -12
