Remark work with the two numbers that are 10^4 first. Then add in the one that goes to 10^3
Method one
You could change these all to integers and then take it back to scientific notation.
83 000
<u>-19 000</u>
64 000
<u>- 2 500
</u> 61 500 <u /><<<<<< answer
Method two
Keep the scientific notation.
8.3 * 10^4
<u>-1.9 * 10^4</u>
6.4 * 10^4
<u>- .25*10^4</u> Note the powers of ten must be the same.
6.15*10^4 <<<<<<<< answer
<u>
</u>Either method works.
<u>
</u>You could use your calculator to get the right answer. I'm not sure all calculators retain the scientific notation. Test yours to see what it does. Enter 8.3*10y^x 4 *1 =
<u>
</u>Your calculator might have x^y or ^ to record powers. You may also have EE and one of your keys.
<u>
</u>See if your calculator returns 8.3*10^4 or if it returns 83000<u>
</u>
Answer:
y=0.1x + 8.4
I hope it will be useful.
The new points will be A' (-6,9) B'(-6,-3)C'(6,-3) then graph them. REMEMBER: if the scale factor is greater than 1 the image will shrink. If the scale factor is less than one the image will enlarge
