Answer:
Perpendicular lines have opposite-reciprocal slopes, so the slope of the line we want to find is 1/2. Plugging in the point given into the equation y = 1/2x + b and solving for b, we get b = 6. Thus, the equation of the line is y = ½x + 6.
Step-by-step explanation:
Answer:
64 feet.
Step-by-step explanation:
From the question given, we can see that the answer has been done half way.
Now, the concluding part can be obtained as follow:
52/78 = x/96
Cross multiply
78 × x = 52 × 96
78x = 4992
Divide both side by 78
x = 4992/78
x = 64 feet
Therefore, the distance 'x' between the lions and monkeys is 64 feet.
