Answer:
D
Step-by-step explanation:
this is a "strategic" guess
1. f(x) = 1
2. f(x) = x
3. f(x) = 5 - x
4. f(x) = 3
Well if d= 20
d=2r
so 20 = 2r
r=10
is that what you wanted, or does this have to do with a circle
1 Expand
1.4t-0.4t+1.24=5.8
2 Simplify 1.4t-0.4t+1.241.4t−0.4t+1.24 to t+1.24t+1.24
t+1.24=5.8
3 Subtract 1.241.24 from both sides
t=5.8−1.24
4 Simplify 5.8-1.245.8−1.24 to 4.564.56
t=4.56
