Answer:
-7, 1
Step-by-step explanation:
The roots of an equation are the answers to the equation, where the graph of the equation intersects the x-axis. One can see that the points at which the graph intersect the x-axis are the following,
(-7, 0) and (1, 0), therefore the roots to the equation are the following;
-7, 1
Answer:
B. 2
Step-by-step explanation:
0.5(m+4) = 3(m-1)
0.5m + 2 = 3m - 3
0.5(2) + 2 = 3(2) -3
1 + 2 = 6 - 3
3 = 3
So, m = 2
Hope this helps
