Answer:
the first one
Step-by-step explanation:
if you do PEMDAS
then i guarantee that it equals to 10
Answer:
2. y=cos x is -pi/2,0 and pi/2/0
3. y= tan x is pi/2, 3pi/2
4. y=sin x is (0,0) and (pi/2,1)
5. y= csc x is (-pi/2,-1) and (pi/2,1)
Step-by-step explanation:
Answer:
DBE=50 degrees
ABD=140 degrees
Step-by-step explanation:
CA is a line which means that it equals 180 degrees total. Subtract the other angle measurements to find that DBE is 50 degrees. Then add the angles DBE, EBF, and FBA. Hope this helps!
Answer: X=1/4 or X=0.25
Step-by-step explanation:
-3+12x
Bring the 3 to the other side to isolate x
12x=3
Divide both sides by 12
x=0.25
-8 and 2
The expression is factorable and is equal to (x+8)(x-2). Using the zero product property, x=-8 because (-8)+8 equals zero and x=2 because 2-2 equals zero.
