Answer:
Step-by-step explanation:
Since y=y for a solution to the system of equations she should just solve
3x-12=-2x+8
Answer:
i think the answer is 7/3
Step-by-step explanation:
hope it helps hun :)
plz mark me brainliest <3
Answer:(d): y=ax+b (a≠0); (d1)y=-4x+13
because of (d)⊥(d1) --> a.(-4)=-1 --> a=
(d): y=
+b. (d) pass through P(-1;-2) so we have
-2=(1/4).(-1)+b ---> b=
(d) y= 
T=(60cos78, 60sin78)
T=(12.47, 58.69)
C=45
d=√((45-12.47)^2+58.69^2)
d≈67.1km
