F(6)=2/3(6)-5
f(6)=4-5
f(6)=-1
Final answer: f(6)= -1
Answer:
The second statement is true.
Step-by-step explanation:
Draw the corresponding parabola and use it to verify all statements.
Y=mx+b where m=slope which is change in y divided by change in x m=(-8-7)/(4-9)=-15/-5=3 so we have y=3x+b now we can use either point, I'll use (9,7), to solve for b or the y-intercept... 7=3(9)+b 7=27+b b=-20so our line is: y=3x-20
m∠C = (1/2)(m arc AB), because ∠C is an inscribed angle.
(5x-7) = (1/2)(2x)
5x-7 =x
4x = 7
x= 7/4 or 1.75
