A: yes because it is a linear equation, and a strait line on the graph. B: Point (0,0) represents when there was no time passed and no blocks walked. C: The unit rate is 10 blocks per 5 mins or 2 blocks per minute (I think that’s what unit rate is) D: point (10,5) I believe. I’m sorry if this is not correct, I tried
Answer: The real answer is - ask 10 students wearing football jerseys each day for a week
Step-by-step explanation: Think about it, chances are that all students they ask that are wearing a football jersey are most likely to favor football. So if you only ask people with a football jersey on, you will not get an accurate answer to represent the entire high school. You should ask people randomly instead of targeting a specific group.
The given set of equations:
y=-3x+1............(1)
y=2x-4 .............(2)
can be solved most conveniently by rewriting as
y =-3x+1 = 2x-4
We concentrate on the right equality, which is expressed in x only:
-3x+1 = 2x-4
Transpose and solve for x
1+4 = 2x+3x
5x=5
x=5/5=1
Substitute x=1 in the
first equation: y=-3(1)+1=-2
second equation: y=2*x-4=2(1)-4=-2
So the solution is x=1, y=-2, or (1,-2)
5x + 3(x - 1) = 8(x + 2 ) - 10
5x + 3x - 3 = 8x + 16 - 10
8x - 3 = 8x + 6
0 - 3 = 6
3 =/= 9
NO SOLUTION.
