Select the expression that is equivalent to (picture)

3 * 10^5  =  3 * 100,000 = 300,000
and
5 * 10^8 = 500,000,000

So the answer is B

3 x 10^5  + 5 x 10^8

300 000 + 500 000 000

Second option.

Abit confused about what you mean, but i think you might be referring to slope intercept form: y = mx + bin that case b, or the y intercept is already given.(0,-1)find the slope by using the formulay2 - y1/x2 - x1the final slope will be 4/2, equivalent to 2.now your equation should look like thisy = 4/2x -1sorry if this didn’t you out!

2160ft^3 i think you could use a formala to you out with this in the future
