Mathematics worksheet

Image attached since I can't type it out

(Btw forgive me for my horrible handwriting D: )

Reasoning:

#4 is a segment which is why it's written like that in the image.

#5 is an angle which is why there is the angle symbol before the PQR

#6 is a line which is why there is a line on top of BY

#7 is an angle which is why there is an angle symbol before LMN

Hope this helped! <3

-14

step-by-step explanation:

2x2 – 2(x+4)

=2x2-2（5+4）

=4-2×9

=4-18

=-14

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50
