Answer:
Step-by-step explanation:
9x+5y=35
Step 1: Add -5y to both sides.
9x+5y+−5y=35+−5y
9x=−5y+35
Step 2: Divide both sides by 9.
9x9=−5y+359
x=−59y+359
Answer:
x=−59y+359
Let's solve for x.
2x+5y=0
Step 1: Add -5y to both sides.
2x+5y+−5y=0+−5y
2x=−5y
Step 2: Divide both sides by 2.
2x2=−5y2
x=−52y
Answer:
x=−52y
Answer:
f(3) = -1
Step-by-step explanation:
given f(x) = -x + 2
to find f(3), we have to replace x with 3
f(3) = -3 + 2
f(3) = -1
Then the total voltage is ...
The magnitude of the resultant voltage is √(.02²+.05²); the angle is arctan(.02/.05).
