I tried doing some equation hope it helps you a little
2-3(x+4)=8
2-3x+12=8
2-3x=-4
-3x=-6
x=2
Answer:
65.03 meters
Step-by-step explanation:
The line of best fit, for the distance of the winning throw, in x years after 1980 is:
![y = 0.34x + 44.63](https://tex.z-dn.net/?f=y%20%3D%200.34x%20%2B%2044.63)
Using the line of best fit, estimate what the distance of the gold medal winning discus throw was in 1980.
1980 - 1920 = 60, so this is y(60).
![y(60) = 0.34(60) + 44.63 = 65.03](https://tex.z-dn.net/?f=y%2860%29%20%3D%200.34%2860%29%20%2B%2044.63%20%3D%2065.03)
So the answer is 65.03 meters.
Cy +y=d - 4
y(c+1)=d-4
y=d-4/c+1
