Answer:
f(x) = -x -1
Step-by-step explanation:
You can make the correct choice by seeing which equation works for the first line of the table.
f(-1) = -(-1) -1 = 0 . . . . . the first equation works
f(-1) = -(-1) +1 = 2 . . . not zero
f(-1) = -1 -1 = -2 . . . not zero
f(-1) = 1 -(-1) = 2 . . . not zero (same as second equation)
50 to 1
100 to 2
150 to 3
200 to 4
It's proportional
Answer:
Part A: t = 2 and y = 7
Part B: Point of intersection is (2,7)
Step-by-step explanation:
Part A: We are given the pair of equations shown below:
y = 8t - 9 ......... (1)
y = 4t - 1 ............ (2)
We can solve those equations by the elimination method.
We have from [equation (1) - equation (2)], 0 = 4t - 8
⇒ t = 2
Therefore, from equation (2), we get y = 4 ×2 - 1 = 7
Hence, t = 2 and y = 7 is the solution of the given pair of equations.
Part B: As equation (1) and equation (2) are two straight lines, so their solution gives the point of intersection of those two lines on the graph.
Therefore, if we plot t along the X-axis and y along the Y-axis then the point of intersection will be (2,7) point. (Answer)
All you have to do is divide 200 by 25.
