Answer:

The answer to your question is: It could be letter A but power 5 is not necessary.

Step-by-step explanation:

Simplify like terms

1.- Remove parenthesis

                                      (3m² + m - 5) + (3 - 6m² + 4m + 5m)

                                       3m² + m - 5 + 3 - 6m² + 4m + 5m

2.- Group like terms

                                      (3m² - 6m²) + (m + 4m + 5m) + (3 - 5)

3.- Simplify

                                     - 3m² + 10m - 2

If the x-intercepts are (-5,0) and (3.0), then the x-coordinate of the vertex is
Leno4ka [110]
If this is for a parabola, then the x-coordinate is -1, since it is directly in the middle of -5 and 3, with 4 spaces on each side (symmetry). The equation is just x = -1 since it just shows the equation of the vertical line which splits the parabola into two equal parts

The black graph is the graph of y=f(x). Choose the equation for the red graph.<br> Please Help!!!
svetlana [45]

Answer:

b

Step-by-step explanation:

The red graph is the black graph horizontally translated to the right.

Given f(x) then f(x + a) is a horizontal translation of f(x)

• If a > 0 then shift to the left of a units

• If a < 0 then shift to the right of a units

Here the shift is 3 units to the right, thus

y = f(x - 3) → b
