Answer:
−c=d−r−a
Step-by-step explanation:
if we move a value to the other side of the equal sign, the value switches positive and negative signs, in this case A moved to the right, which caused it to turn negative.
Answer: BOC is 80 COD is
60 (i think I’m not sure)
Step-by-step explanation:
DOF is 120 minus 40 (cuz it’s a vertical angle and is parallel from the other one) is 80 and I got 60 for COD because 80+80+40+40=240 a circle is 360 so 360-240=120 and since it’s two vertical angles you have to divide it by 2 to get 60. Again thts only what I think so Idk if it’s right or not this is what I think the answer is.
Answer:
The answer is option 1.
Step-by-step explanation:
Axis of symmetry means the middle x-coordinates of the parabola. So in order to find the x value, you have to find the TP which is Turning Point by using Completing the Square :
Let y = 0,
Next, you have to solve the x value :
x + 3 = 0
x = -3
