When do you use a solid line for graphing a linear inequality?

When the equation your graphing is either less than or equal too or greater than or equal too

Step-by-step explanation:

When the line is dotted, the equation graphed was either less than or greater than

So then the line is solid, it mean the equation graphed was either greater than or equal too or less than or equal too

I hope this helps!

there is no grid

step-by-step explanation:

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.
