Answer:
Step-by-step explanation:
solve for v
-2v + v = 3
combine like terms
-v = 3
divide by -1
v = -3

Step-by-step explanation:
Answer:
(0,-8/3)
Step-by-step explanation:
2x-3y=8
x-3y=8
Multiply the second equation by -1 and add together
2x-3y=8
-x+3y=-8
---------------------
x +0y =0
x=0
Now we can find y
2x -3y =8
0-3y =8
Divide by -3
-3y/-3 = 8/-3
y = -8/3
(0,-8/3)
Answer:
x = 0, π/3, π, 5π/3
Step-by-step explanation:
sec(x)sin(x) - 2sin(x) = 0
factor out sin(x)
sin(x)[sec(x) - 2] = 0
then solve by splitting into two parts:
sin(x) = 0 and sec(x) - 2 = 0
x = 0, π and x = π/3, 5π/3 then plug in to original equation to check
Answer:32
Step-by-step explanation: First you do 4×4×4×
=64 then you divide by 2.. 64÷2=32
