Answer: y = 3/2x + 1
Step-by-step explanation: For a perpendicular line, take the reciprocal of "m" and reverse the sign.
- 2/3 becomes +3/2
Then substitute the y and x values of the given coordinate into the equation and solve for "b"
y = mx + b
-2 = 3/2(-2) + b
-2 = -3 + b
-2 +3 = b
+1 = b Substitute for b in y = (3/2)x + 1
That would be (126 - 120) / 120 = 5/120 = 5%
Its b
Answer:
The initial Carla's balance was $96
The equation is x-7=89
Step-by-step explanation:
Let
x ----> initial Carla's balance
we know that
The linear equation that represent this problem is equal to
x-7=89
solve for x
Adds 7 both sides
x=89+7
x=$96

I would love to help you...but where's the question?
Answer:
30 km/h
Step-by-step explanation:
usual speed= x km/h
increased speed= x +10 km/h
distance= 360 km
time difference= 3 h
- 360/x= 360/(x+10) +3
- 360/x= (360+ 3x+30)/(x+10)
- 360(x+10)= x(390+3x)
- 360x+3600= 390x+ 3x²
- 3x² + 30 x -3600=0
- x²+10x-1200=0
- x=30 km/h
