Answer:
e) 1 / 2
f) -3 / 2
Step-by-step explanation:
e) line passing through points (1,1) (3,2)
you can count coordinates by blocks
slope = (y2 - y1 ) / (x2 - x1)
= (2 - 1) / (3 -1 )
= 1 / 2
f) line passing through points (0,0) (-2,3)
slope = (y2 - y1 ) / (x2 - x1)
= (3 - 0) / (-2 - 0)
= 3 / -2
= -3 / 2
Answer:
His answer is wrong.
Step-by-step explanation:
-4(6-R)=12 <-- Since R is negative, -4 times -R results in a positive so, 4R.
-24+4R=12
+24 +24
--------------------
4R = 36
R= 9
Answer:she had it 3 hours
Step-by-step explanation:
The integer that represents the change in temperature from 8:00 am, to 8:00 pm would be 11. Change in temperature would mean the difference between T2 and T1 and this would be 3-(-8) = 11. Hope this answers the question. Have a nice day.
