Answer:
a. 63k + 42m
b. -72 + 30c
c. 6e + 6f - 237
Hope this was helpful :-)
Slope point form is y2-y1 = m(x2-x1)
so in this case the left side is -4
m is rise/run (4/8)
and lastly the term for m is -8
seems that they want it in a diff form so well just ignore all of what i just did
(3-(-1)) = 1/2(-5-3)
When ANY number is multiplied by its own reciprocal, the product is ' 1 '.
Answer:
A and D are probably the answers
Step-by-step explanation:
Answer:
Correct option: first one -> 45°
Step-by-step explanation:
FC is a diameter, so the arc FBC measures 180°.
If we have that FBC = FB + BC, then we can find the value of BC:
FB + BC = 180
135 + BC = 180
BC = 45°
If we call the center of the circle 'O, we have that the central angle EOF and the central angle BOC are vertically opposite angles, so EOF = BOC.
The central angles have the same measure that the arcs they are related, so we have that:
angle BOC = arc BC = 45°
angle BOC = angle EOF
angle EOF = arc EF = 45°
Correct option: first one
