Answer:

2 x

Step-by-step explanation:

A simple way of determining a derivative of an expression is that the power is brought down and the new power is reduced by 1. For example,

d/dx [x^3] = 3x^2.

d/dx [2x^3] = 2(3)x^2

= 6x^2

Hence derivative if x^2 = 2x^1 = 2x

Solve negative 5 over 2, the whole multiplied by x minus 5 equals negative 55.

astraxan [27]

Answer:

-24

Step-by-step explanation:

$- \frac{5}{2} x \: - 5 = 55$

Multiply through by the denominator (that is, 2)

$= 2 \times ( - \frac{5}{2} x) \: - 5(2) = 55(2)$

$= - 5x - 10 = 110$

Collect like terms

$- 5x \: = 110 +10$

$- 5x = 120$

Divide through by - 5x

$\frac{ - 5x}{ - 5} = \frac{120}{ - 5}$

$x = - 24$
