It is the last choice. The root power becomes the denominator.
So, a^3/4b^1/4
You draw the reference angle of 45° but clockwise. The exact value of sin(-345°) is 1/√2.
Answer:
B
Step-by-step explanation:
y=sec(x+pi/2)
Took the test on e2020
Answer: x=-2
Y= -20
Step-by-step explanation
You replace the y in the second equation with 10x. This is because it says 10x=y
2x+10x=12x so you put that
12x=-24
To get x by its self you divide by 12.
-24 divided by 12 is -2.
Now you plug in -2 to either equation as y. I chose the first one because it's easier.
10(-2)=y
-20=y
