Guided Practice Find the midpoint of the segment with the given endpoints.

S(9, 12) and U(–9, –12)

A.
(10.5, 10.5)

B.
(9, 12)

C.
(0, 0)

i would think its C

Step-by-step explanation:

the other options dont make sense lol

hope this is correct and helps :)

c. (0,0)

Step-by-step explanation:

The midpoint between 9 and -9 is 0, because 9 to 0 is 9, and -9 to 0 is 9.

The midpoint between 12 and -12 is 0 as well, because 12 to 0 is 12, -12 to 0 is also 12.

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.
