Me calculate the proper number of significant figures, i would like to check my answers to see if this is correct based on the significant figure rules
a.) 320.80−(6101.3/1.8)320.80−(6101.3/1 .8)=
b.) [(286.4×105)−(1.300×103)]×2.8951= c.) (0.0041×26000.0)+(2811×15)=
d.) 863×[1251−(3.11×109)]=

I

don't know

Step-by-step explanation:

i have no I dea

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
