Answer:
Step-by-step explanation:
<u><em># 21.</em></u>
÷ ( - 0.35 ) = - ÷ 
= - ÷ 
= - × 
= - 
<em>(B).</em>
<u><em># 22.</em></u>
( 
- 
) ÷ ( - 2.5 )
= 
= 3.5
= 
= 
= 9.75
( 3.5 - 9.75 ) ÷ ( - 2.5 ) = ( - 6.25 ) ÷ ( - 2.5 ) = 2.5 <em>(D).</em>
6/7 is not a whole number.
6/7=0.857
If you want, you can round 0.857 to a whole number.
0.857 as a whole number would be 1.
We need Vector ST which is just T - S
(7-3.4-2) = (4,2)
So now we need the perpindicular. The easiest way to do this, is to know that , in R2 that the perindicular is just the negatice inverse. So its (2,-4)
