Answer: 2
Step-by-step explanation: add 10 to both sides so -10+10=0 and -6+10=4
then you have 2x=4 simplify
Answer:
x=30°
Step-by-step explanation:
3x-10=2x+20
3x-2x=20+10
x = 30°
just x, no y in the photo
r = sqrt ( (-2)^2 + (2sqrt3)^2)
= sqrt (4 + 12) = 4
tan theta = 2 sqrt 3 / -2 = -sqrt3
theta = 2pi/3
The correct option is C
Answer:
x²-7 = 0 part 1 and part 2 : x = sqrt(7) or x = -sqrt(7)
Step-by-step explanation:
Solve for x:
x^2 - 7 = 0
Add 7 to both sides:
x^2 = 7
Take the square root of both sides:
Answer: x = sqrt(7) or x = -sqrt(7)
