hope this helped, im better at algebra tho :)
Answer:
y - 2 = 1/2(x - 3)
Step-by-step explanation:
In this question, we need to write the given information in point-slope form.
Point-slope form: y - y1 = m(x - x1)
We know that our slope is 1/2
We are also given a coordinate: (3, 2)
Plug in the information to its correct spot in the equation:
y - 2 = 1/2(x - 3)
Your point-slope form would be: y - 2 = 1/2(x - 3)
If an adult blinks 450 times in 30 minutes, then he will blink 900 times in 60 minutes.
A 12-year old blinks 150 times in 15 minutes, so he will blink (150 x 4) in 60 minutes, which comes out to: 600.
so 900-600
An adult blinks 300 times more in 60 minutes than a 12-year old.
Answer:
c = b -d/a
Step-by-step explanation:
a(b-c)=d
Divide each side by a
a(b-c)/a = d/a
b-c = d/a
Subtract b from each side
b-c-b = d/a -b
-c = d/a -b
Multiply each side by -1
c = -d/a+b
c = b -d/a
Answer:
Step-by-step explanation:
To overestimate the area would mean that you completely enclose the circle in squares; an 8 x 8 square to b exact. The area of a square with sides measuring 8 is 64. The overestimation is 64.
To underestimate the area would mean that you only count the squares that are completely inside the circle. That would be a 6 x 6 square (even though the 6th squares are a tiny bit outside the circle). A square with sides of 6 has an area of 36. The underestimation is 36.
