Answer:
x=30
Step-by-step explanation:
Sin = opposite/hypotenuse
Im not sure why you said ur wrong b/c i got the same answer
f(x) = -15+ 7
f(x) = -8
Answer:
Step-by-step explanation:
r=3 cos 5∅
change ∅ to -∅
r=3cos(-5∅)=3 cos (5∅)
so it does not change.
Hence it is symmetric to x-axis.
change r to -r
-r=3 cos 5∅
or r=-3 cos 5∅
so eq. changes .
Hence it not symmetric to y-axis.
Answer:
Step-by-step explanation:
Step 1: Subtract 3x from both sides.
5x−4−3x=3x+18−3x
2x−4=18
Step 2: Add 4 to both sides.
2x−4+4=18+4
2x=22
Step 3: Divide both sides by 2
2x/2= 22/2
x= 11
