Planet earth has a mass of 5.9726 × 10 24 kilograms. and although 70% of the earth's surface is made of water, the water's mass is only 5 × 10 -4 percent of the earth's total mass. use scientific notation to estimate the mass of the planet's water. in your final answer, include all of your estimates and calculations.

y = 3x+4

step-by-step explanation:

to find the slope

slope = (y2-y1)/ (x2-x1)

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4

3

step-by-step explanation:

there should be an link icon on the bottom of the text box you get. it looks like a paperclip!

step-by-step explanation:

total income = price of one ticket   *   number of tickets sold

  y                 =     4                                   x

so the equation is y=4x     with x≥0   because number of tickets sold can not be negative

thus the equation is a semi -line with an end point at

(0,0)

passing through :

x=1     y=4(1) = 4   so through (1,4)
