Answer:
B, C, E
Step-by-step explanation:
Distributing the minus sign in the given expression results in ...
6x +1 -3x -(-1)
6x +1 -3 +1 . . . . simplify
The two expressions that show the constant terms as +1 - 1 are erroneous. The two constant terms are +1 -(-1) or +1 +1.
The correct expressions are the 2nd, 3rd, and 5th ones (b, c, e).
Answer:
1. 18
2. 6
3. ?
4. 3
5. 4
6. 1
7. 5
Step-by-step explanation:
1. 6 x 3 = 18
2. 2 + 4 = 6
3. ( I cant read the problem)
4. 6 - 3 = 3
5. 2 x 2 = 4
6. 3 ÷ 3 = 1
7. 6 - 1 = 5
8. 6 + 2 = 8
From the graph shown it can be seen that the bridge is represented by a parabola with vertex of (5, 8) and roots of 1 and 9.
Recall that the vertex form of the equation of a parabola with vertex (h, k) is given by

Thus, the equation of the given graph in vertex form is given by

Also, recall that the equation of a parabola with roots, p and q, is given by

Thus the equation of the given graph can be given by

To get the value of a, we equate both equations and solve as follows:
