(05.03 mc) part a: explain why the x-coordinates of the points where the graphs of the equations y = 4x and y = 2x−2 intersect are the solutions of the equation 4x = 2x−2. (4 points) part b: make tables to find the solution to 4x = 2x−2. take the integer values of x between −3 and 3. (4 points) part c: how can you solve the equation 4x = 2x−2 graphically? (2 points)

Step-by-step explanation:

Given that there are two graphs y =4x and y =2x-2

To find the point of intersection, we must find (x,y) which satisfy both the equations.

FOr such a point then we have y coordinates equal and hence 4x=2x-2

Part B:

x    4x      2x-2

-3     -12      -8

-2      -8      -6

-1      -4      -4

0     0        -2

1       4        0

2        8      2

3       12       4

Thus we find that x=-1 is the solution

Part C

answer: two angles are called supplementary if they add up to 180°. example: the two angles (140° and 40°) are supplementary because they add up to 180°.
