Which of the following expressions are equivalent to –3.5(2 – 3n) – 2.5n? a: –7 – 8n . b: –7 + 8n . c: –7 – 13n . d: –7 – n(10.5 – 2.5) . e: –7 + n(10.5 – 2.5)

step-by-step explanation:

here's what happens:

1) the graph of f   = x^2 is shifted 2 units to the right.

2) the resulting graph is reflected in the x-axis, so that the parabola now opens down.

3) this final result is transformed up by 5 units.

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571
