The graph of the equation is Ax+2y =-2 is the line that passes through (2,-2) what is value A
1 answer:
Answer:
The value of A in the given graph of the equation is 1
That is A=1
Step-by-step explanation:
Given graph of the equation is Ax+2y=-2
Given that the equation of line Ax+2y=-2 passes through the point (2,-2)
Let (x,y) br the point (2,-2)
Therefore we have that
A(2)+2(-2)=-2
2A-4=-2
2A-4+2=-2+2
2A-2=0
2A=2
Therefore A=1
Therefore the value of A in the given graph of the equation is 1

Answer:
Outside temperature at 2 A.M = -33.2°C
Step-by-step explanation:
Given:
Temperature at 12:00 midnight (outside) = -30.9°C
Rate of decreases = - 2.3°C per two hour
Find:
Outside temperature at 2 A.M
Computation:
Outside temperature at 2 A.M = Temperature at 12:00 midnight (outside) + Rate of decreases
Outside temperature at 2 A.M = -30.9°C + (- 2.3°C)
Outside temperature at 2 A.M = -33.2°C
