The tangent line is perpendicular to the radius, so will have slope
.. -1/2.5 = -0.4 . . . . . . corresponding to the 3rd selection
<span>6-t/2t+9 = -2
multiply both sides by 2t+9
which will give you
6-t= -2(2t+9)
6-t = -4t + 18
now add 4t to both sides
6 -t + 4t = -4t -18 + 4t
6 + 3t = -18
6-6 + 3t = -18 -6
3t = -24
t = -24/3
t= -8 (negative 8)

Answer:
y=8x+7
Step-by-step explanation:
Use the form y=mx+b
M= the slope
B= the y-intercept
y=8x+?
Since the y coordinate of (0,7) is 7
b=7
So y=8x+7
What we are going to do in this case is to calculate the number of races allowed per inning.
We have then:
Randy pitched 3 innings and allowed 2 runs:
(2/3) = 0.666666667
Felix pitched 5 innings and allowed 4 runs:
(4/5) = 0.8
Johan pitched 7 innings and allowed 5 runs:
(5/7) = 0.714285714
Answer:
Randy has the lowest number of runs allowed per inning
