Divide 22 by 2 to get "c" isolated.
The length of AA' is the squareroot of 29.
K= -3
3y = x+6 can be rewritten as y = 1/3x + 2
a perpendicular slope is the opposite reciprocal of the original slope
so instead of 1/3 it would be -3
therefore. k must equal -3 to be perpendicular to 3y = x+6
Answer:
27.74 is the difference
Step-by-step explanation:
23.3° C - (-4.44° C)
23.3 + 4.44
27.74
