1a. 6y - 2y = 4y

1b. 6 - 7b + 7b + 3 + b

= 6 + 3 + b

= 9 + b

2a. 10a - 2 + 3 - a

= (10a - a) + (-2 + 3)

= 9a + 1

2b. m · 7 · m · m · m · m · 9

= (7 · 9) · (m · m · m · m · m)

=63m^{5}

3a.  3 + 8(5a + 10)

= 3 + 40a + 80

= 40a + 83

3b.  6v - 8v + 4 + 6v

= (6v - 8v + 6v) + 4

= 4v + 4

4a.  s · 1 · s · 3

= (1 · 3) · (s · s)

= 3s^{2}

4b.  6k - 6k

= 0

5a.  10y^{4} (y^{2} )

= =10y^{6}

5b.  10x + 7 - 5x

= (10x - 5x) + 7

= 5x + 7

6a.  1v - v + 7 + 9v

= (1v - v + 9v) + 7

= 9v + 7

6b.  6z - 5 + 5 - 6z

= (6z - 6z) + (-5 + 5)

= 0 + 0 = 0

7a.  9w + 5w

= 14w

7b. s · 2s · s · s · s · s

= 2 · (s · s · s · s · s · s)

= 2s^{6}

Which equation matches the graph below?
Oksana_A [137]

Answer:Given that the graph shows tha the functión at x = 0 is below the y-axis, the constant term of the function has to be negative. This leaves us two possibilities:

y = 8x^2 + 2x - 5 and y = 2x^2 + 8x - 5

To try to discard one of them, let us use the vertex, which is at x = -2.

With y = 8x^2 + 2x - 5, you get y = 8(-2)^2 + 2(-2) - 5 = 32 - 4 - 5 = 23 , which is not the y-coordinate of the vertex of the curve of the graph.

Test the other equation, y = 2x^2 + 8x - 5 = 2(-2)^2 + 8(-2) - 5 = 8 - 16 - 5 = -13, which is exactly the y-coordinate of the function graphed.
