Answer:
3
Step-by-step explanation:
Arc length = radius × angle
s = r θ
60 cm = 20 cm × θ
θ = 3 radians
Let us always base on the present age. We denote this by x. Now, the age he had 2 years ago would then be denoted as (x-2). Let's equate this to 20 years old.
x - 2 = 20
x = 20 + 2
x = 22 years old
He should be 22 years old now.
Let's check the other condition. After 1 year, his age should be (x+1). Let's equate this to 23 years old.
x + 1 = 23
x = 23 - 1
x = 22
Thus, this is possible if Reuben is 22 years old as of the present.
Answer:
1 ) y = 2x - 1
slope = 2
y intercept is (0,-1)
2) y = -1/2x + 5
slope = -0.5
y intercept = (0,5)
Step-by-step explanation:
Answer:
m=2
Step-by-step explanation:
slope is the average rate of change in a specific interval
we can calculate slope in this case with Δy/Δx or (y2-y1)/(x2-x1)
m=(y2-y1)/(x2-x1)
=(-1-7)/(-3-1)
=-8/-4
=2
Answer:
48
Step-by-step explanation:
