Answer:
t= 67
Step-by-step explanation:
because you combine the terms and add it together
Answer: i can try
Step-by-step explanation:
F(x)=x²+3x ; [-2;3]⇒Δf/Δx=(f(3)-f(-2))/(3-(-2))=4 (A)
f(x)=3x-8 ; [4;5]⇒Δf/Δx=<span>(f(5)-f(4))/(5-4)=3 (B)
f(x)=x</span>²-2x ;[-3; 4]⇒<span>Δf/Δx=(f(4)-f(-3))/(4-(-3))= -1 (C)
f(x)=x</span>²-5 ;[-1; 1]⇒<span>Δf/Δx=(f(1)-f(-1))/(1-(-1))= 0 (D)
answer: A, B, D, C

Answer:
You start at -9
-Open circle
-shade towards the right (where all the positive numbers are)
Open circle - ones that don't have a greater than or equal to. If it does then it's a closed one.
Shade towards the right cause y is less than 9
9x-7=-7
+7 +7
___________
9x= 0
_ _
9 9
x=0
