Answer:
y = 5x + 8
Step-by-step explanation:
Start with y = mx + b: general slope-intercept form, equation of a line:
Replace m with 5, y with 8 and x with 0 (since the y-intercept is (0, 8):
8 = 5(0) + b. Then b must be 8, and the desired equation is
y = 5x + 8
X³ - 2x² - 5x = 0
First, take common factor:
x(x^2 - 2x - 5 )= 0
Now use the quadratic formula to find the roots of the trinomial
x = [- b +/- √(b^2 - 4(a)(c)] / 2a
x = [2 +/-2√6 ]/2
x = 1 + √6 and x = 1 -√6
Then the solutions are:
x =0; x = 1 + √6; x = 1 - √6
That is the las option shown.
It's not time to try and simplify it until you HAVE an equation. You won't have an equation until you write down what. V*4x is equal to.

Answer:
Atlanta Mean price:
= Sum of all prices / Number of prices
= (340.1 + 321.6 + 291.6 + 339.6 + 359.6 + 384.6 + 309.6 + 415.6 + 293.6 + 249.6 + 539.6 + 455.6 + 359.6 + 333.9) / 14
= 4,994.2 / 14
= $356.73
Salt Lake City mean price:
= (570.1 + 354.6 + 465.6 + 219.6 + 311.6 + 297.6 + 471.6 + 618.4 + 513.2 + 381.6 + 159.6 + 267.6 + 458.6) / 14
= 5,613.3 / 14
= $400.95
