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)
We know the full protractor measures 180 degrees.
We need to know what angle it is on. By looking at it, it looks like it is on 135.
180-135= 45
The angle is 45 <em>degrees.
