Answer:

3/2

Step-by-step explanation:

Pick two points on the graph

(-1,2) and (3,8)

We can use the slope formula

m= ( y2-y1)/(x2-x1)

   = ( 8-2)/(3 - -1)

   = (8-2)/(3+1)

   = 6/4

  = 3/2

Annie says the two expressions are equalized. Is she correct? Explain using different strategies -3x+6 and 3(-x -2).
borishaifa [10]

Step-by-step explanation:

By using Distributive Property on 3(-x - 2),

3(-x - 2) = (3)(-x) + (3)(-2) = -3x - 6.

Since -3x - 6 =/= -3x + 6,

they are not equalized.

A scientist measures a substance to be 0.6 grams. Calculate the percent of error in the measurement. Show all work for full cred
Anni [7]
A measurement of 0.6 grams means that the 'true' answer lies between
<span>0.55 and 0.65 </span>

In general, the uncertainty in a single measurement from a single instrument is half the least precise decimal given for the instrument.
The precision for this measurement is in the tenths place.
so we take 0.1 /2 = 0.05, and divide by the measurement

<span>0.05 / 0.6 = 0.08333 = 8.3 %</span>
