What is the solutions of x2 = –5x + 8?
topjm [15]

Answer:

x=\sqrt{14.25} -2.5, x=-\sqrt{14.25}-2.5

Step-by-step explanation:

Since moving it to one side can't be factored, I'm going to complete the square.

x^2+5x=8

x^2+5x+6.25=8+6.25

(x+2.5)^2=14.25

x+2.5=\sqrt{14.25}

x=\sqrt{14.25} -2.5, x=-\sqrt{14.25}-2.5

Natalija [7]

Answer:

The ratio of the income in 2003 would be $54,300.

Step-by-step explanation:

Given that the yearly income for an individual with an associate degree in 2001 was $53,166 and 2013 was $59,970, we can determine that in 12 years there was a wage increase of $ 6,804 (59,970 - 53,166). Thus, on average, each year there was a salary increase of $ 567 (6,804 / 12). Therefore, given that in 2003 two years had passed since the starting value of $ 53,166, following this reasoning and without inflationary or recessionary changes, this person's salary should have been $ 54,300 (53,166 + 567 x 2).

Mumz [18]
It is presumed that the 10m is the vertical distance in 4 floors so 10meters divided by 10 seconds is 1m/second is the average speed of the escalator. Hard to add anything to this to make up to the required 40 words.
