A/b times b/c is = ab/bc
which can be written as a/c times b/b
anything over itself is 1 so b/b is one
a/b times b/c = a/c
Answer:
are we suposed to pick one
Step-by-step explanation:
i would pick B aka 2
The second choice for the first problem and the third choice for the second problem
Answer: The answer is y=-1/3x+2.
Explanation:The slope equals,m=-1/3,when you do the rise over run method.Then the y-intercept equals,b=2,so that is how you get the answer y=-1/3x+2.
Solve for w over the real numbers:w (9 w^2 - 7) = 0
Split into two equations:w = 0 or 9 w^2 - 7 = 0
Add 7 to both sides:
w = 0 or 9 w^2 = 7
Divide both sides by 9:
w = 0 or w^2 = 7/9
Take the square root of both sides:
Answer: w = 0 or w = sqrt(7)/3 or w = -sqrt(7)/3
