solve for b.
a−2b=−10
Add -a to both sides.
a−2b+−a=−10+−a
−2b=−a−10
Divide both sides by -2.
−2b/−2 = −a−10/−2
b=1/2a+5
Answer:
5i
Step-by-step explanation:
-25 can be written as 25 x -1
so root -25 is equal to root 25 x -1
root -1 can also be written as i
so root -25 is root 25 multiplied by i
simplifiying this to 5i
Answer:
