The exact value of sin (-270) is determined using the calculator in degrees mode. The answer is equal to 1. If the radians mode is used, -270 is equal to -2 pi/3. Hence using the calculator, we can verify that the answer is still 1. The value of -270 matters.
Answer:
Yes because the answer to both of them is 1
Step-by-step explanation:
Let's solve your equation step-by-step.
−2x+9=7
Step 1: Subtract 9 from both sides.
−2x+9−9=7−9
−2x=−2
Step 2: Divide both sides by -2.
−2x
−2
=
−2
