Answer:
Put an open dot on -10 and an open dot on 1 and draw a line between them
Step-by-step explanation:
Answer: I think the answer would be nine. Hear me out
Step-by-step explanation: The left triangle has the angles 5 and 4, so the right answer for the other side would be the angles 8 and x=9.

take the derivitive to find the slope


so at x=1, the slope is f'(1)=6(1)^2-4=6-4=2
y=mx+b
y=2x+b
find b
at x=1, f(1)=2(1)^3-4(1)=2-4=-2=y
-2=2(1)+b
-2=2+b
-4=b
equation is y=2x-4
