I don't know the rest but good luck.
Answer: I would need a picture of the exact set up of the question but I think it would go.
T=4b
B= 9
Step-by-step explanation:
Answer:
1)2/3d0 Find the value of X satisfying the mean-value theorem. x?dx ...
1/(x+3) = 7/(4x+12) - 2
1/(x+3) = 7/(4(x+3)) - 2
1/z = 7/(4z) - 2 ..... let z = x+3
4z*[1/z] = 4z*[7/(4z) - 2]
4 = 7 - 8z
4-7 = 7 - 8z - 7
-3 = -8z
-8z = -3
-8z/(-8) = -3/(-8)
z = 3/8
x+3 = 3/8 .... replace z with x+3
x+3-3 = 3/8 - 3
x = 3/8 - 24/8
x = (3-24)/8
x = -21/8
The final answer, as a fraction, is x = -21/8
If you want the answer in decimal form, then using a calculator we can say -21/8 = -2.625
ok so we see that TR is 17 units, so RV is the same amount
3x+2 so 3x=15 so divide both sides by 3 we get x=5
now we know x=5 4x+1=21 and 9x-4=41
