question 2:
a.)+8

c.)+32.5
.5

y = 8x-32.50

Step-by-step explanation:

She makes 8 dollars an hour babysitting.  She will work x hours

She makes 8x

She owes 32.50 to her friend.  This will be subtracted because she owes it

The amount of money she has at the end, y, is given by

y =8x-32.50

tangent

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.
