Answer:
d. put an equal sign between the two expressions, and solve for x
Step-by-step explanation:
The two expressions are :
and
We can say that is LHS and we have to solve it to become equal to RHS or
Now we have to tell procedure can Ahmed follow to determine if the two expressions are equivalent. For equivalent equations we put an equal sign between the expressions and solve them.
Solving LHS or
Cancelling out 4 we get:
or the RHS
Therefore, option D is the correct answer.

Answer: (-2, 5) and (2, -3)
<u>Step-by-step explanation:</u>
Graph the line y = -2x + 1 (which is in y = mx + b format) by plotting the y-intercept (b = 1) on the y-axis and then using the slope (m = -2) to plot the second point by going down 2 and right 1 unit from the first point:
y - intercept = (0, 1) 2nd point = ( -1, 1).
Graph the parabola y = x² - 2x - 3 by first plotting the vertex and then plotting the y-intercept (or some other point):
vertex = (1, -4) 2nd point (y-intercept) = (0, -3)
<em>see attached</em> - the graphs intersect at two points: (-2, 5) and (2, -3)
