Answer:
Points of intersection: (1.225,-1.58) and (1.225,1.58)
Step-by-step explanation:
Given
Required
The region area
Plot the graphs of and
Make y the subject in both equations
Square both sides
Rewrite
Take square roots
So, we have:
Take square roots
So, we have:
The point of intersection is:
Square both sides
Collect like terms
Divide by 2
Take square roots
So, the point of intersection is at: (1.225,-1.58) and (1.225,1.58)

Answer:
7 inches
Step-by-step explanation: Every 1 inch = 50 miles. So every 50 miles of tunnel is 1 inch in a scale drawing. 350miles/50 miles=7 inches.
The scale drawing is 7 inches.
Answer:
y = 3/2x + 7
Step-by-step explanation:
y - 1 = 3/2 (x + 4)
y = 3/2x + b
1 = 3/2(-4) + b
1 = -6 + b
7 = b
Answer:
375 kilometers
Step-by-step explanation:
