Solve 3[-x + (2 x + 1)] = x - 1.<br> x = 2

Gekata [30.6K]

Answer:

x = -2

Step-by-step explanation:

$3[- x + (2x + 1)] = x - 1$

$= > 3[ - x + 2x + 1 ] = x - 1$

$= > 3[x + 1] = x - 1$

$= > 3x + 3 = x - 1$

$= > 3x - x = - 1 - 3$

$= > 2x = - 4$

$= > x = \frac{ - 4}{2} = - 2$

How do u compare rate of change and slope help plz

antoniya [11.8K]

Step-by-step explanation:

The slope is described by the the initial and final value of one quantity over the difference between the initial and final of the other

Rate: for points on a Cartesian plane,(x1, y1) and (x2, y2)

the slope, m= (y2 - y1)/(x2 - x1)

The rate of change on the other hand is mostly refers to how much a quantity is changing with time i.e the rate of change of y from y1 to y2 can be expressed as

rate = (y2 - y1)/(t2 - t1)...where t1 and t2 are the various time in y1 and y2 respectively...
