Answer:
y-6=1/2(x-4)
Step-by-step explanation:
y-y1=m(x-x1)
y-6=1/2(x-4)
Answer:
The first submarine needs to travel at a rate of [-180 – (-1,320)] ÷ 60 = 19 feet per minute. The second submarine needs to travel at a rate of [-180 – (-1,440)] ÷ 60 = 21 feet per minute.
Answer:
y =4/5x + 3
Step-by-step explanation:
−4x−6=−5y+9
Step 1: Flip the equation.
−5y+9=−4x−6
Step 2: Add -9 to both sides.
−5y+9+−9=−4x−6+−9
−5y=−4x−15
Step 3: Divide both sides by -5.
−5y/−5
=
−4x−15/−5
y=
4/5x+3
Answer:
y=
4/5x+3
The largest area that can be enclosed will be that of a square (140 ft)/4 = 35 ft on a side. Such a square has an area of (35 ft)² = 1225 ft², not enough for the garden to be 1300 ft². This tells us the solution to the equation you're being asked to write is non-real.
_____
Putting the given numbers in the area equation, you have
... 1300 = 70w -w²
Multiplying by -1 and completing the square, we have
... w² -70w +35² = -1300 +35²
... (w -35)² = 1225 -1300 = -75
Taking the square root shows us the solution is non-real.
... w - 35 = ±√(-75) = ±5i√3
... w = 35 ± 5i√3 . . . . . . . . . after adding 35. These are complex solutions.
