Answer:
That can be re-written:
x^2 + 5x -8 = 0
We use the Quadratic Formula
a=1
b = 5
c = -8
x = [-b +- sq root (b^2 - 4ac) ] / 2a
x = [-5 +- sq root (25 - - 32)] / 2
x1 = [-5 + sq root (57)] / 2
x1 = 1.27491722
x2 = [-5 - sq root (57)] / 2
x2 = -6.2749172176

Answer:
62.5% increase
Step-by-step explanation:
First step : find the difference between two numbers, in this case, it's 1300000 - 800000 = 500000.
Second Step: Take the difference, 500000, and divide by the original number: 500000/800000 = 0.625.
Last, multiply the number above by 100: 0.625*100 = 62.5%. You're done! You calculated difference of a number in percent, and the answer is a percentage increase of 62.5%.

A) a scattershot graph is a good choice for this data because it’s easier for estimation and reading , a scatershot graph is like a line graph but for equations where you don’t connect the line
