Acc. to midpoint theorem,
15={(2x+9) + (4x-15)}/2
⇒ 30=2x+9+4x-15
⇒ 30-9+15=6x
⇒ 36/6=x
⇒6=x
WZ= 4x-15
=4*6-15
=24-15=9
Answer:
√308 or 17.5
Step-by-step explanation:
c^2=a^2+b^2
c^2-a^2=b^2
Substitute
18^2-4^2=b^2
324-16=b^2
b^2=308
b=√308 or b=17.5
Answer:
For the given functions, the value of g(5)-f(5) = 17
Step-by-step explanation:
Here, the given functions are:
f(x) = -3x + 17

So, f(5) = -3(5) + 17
= -15 + 17 = 2
And 
So, f(5) = 2 and g(5) = 19
⇒g(5) - f(5) = 19 - 2 = 17
Hence, for the given functions, the value of g(5)-f(5) = 17
