<span>Let x=0.8888...
x=0.8888 Start with the given equation
10x=8.8888 Multiply both sides by 10. The goal is to move the decimal point to the next repeating portion (which is just one spot to the right)
Now subtract the equation x=0.8888 from 10x=8.8888 to get
10x-x=8.8888-0.8888
9x=8 Combine like terms. Notice how the decimal portions cancel out.
x=8/9 Divide both sides by 9 to isolate x
So the answer is x=8/9 which means that 8/9=0.8888 (where the 8's repeat)</span>
Answer:
y=-2
Step-by-step explanation:
y-y1=m(x-x1)
m=(y2-y1)/(x2-x1)
m=(0-(-2))/(-5-(-5))
m=(0+2)/(-5+5)
m=2/0
y-(-2)=0
y+2=0
y=0-2
y=-2

Answer:
, 
Step-by-step explanation:
The velocity function of the projectile is obtained by deriving the position function:
Now, the velocities after 3 and 15 seconds are, respectively:
12 times 2 + 9 times 2 = 24 + 18 = 42 divided by 16 = 2.625
