At first it was this. Then I think we got rid of the negatives and made it positive.
Therefore using the equations
2(a sub x) + b sub x
and
2(a sub y) - b sub y
Oh so you're saying what I should've done was
x: 14.82 - 77.7
y: 21.97 - 41.2
Is that so? And If you looked at the 26.5cos56. I thought it was -26.5cos56. But my teacher said the sign negative sign didn't matter or something. What does he mean?
Homework Statement
What is the magnitude and angle to
Vector B - 2(Vector A)?
Homework Equations
A sub x: 44cos28 = 38.85
A sub y: 44sin28 = 20.66
B sub x: 26.5cos56 = 14.82 <-- (Does the negative sign matter in 26.5? My teacher said it's not)
B sub y: 26.5sin56 = 21.97

I completely understand now. Thank you very much and sorry for such a late reply. What you did was work with each equation individually. Sorry fro not understanding so fast. My brain takes in things differently than most people. When using math terms, I'm not that well at interpreting it unless...
\frac{5x + 1}{x - 1} ≥ 7
That is what I meant. Sorry. My first time using the forums. I didn't know what I was doing. Now I am still confused on how to solve this. As I mentioned before, in my method of solving this I ended up with a one inequality solution: x ≥ 4
Why is that that's not the...
Homework Statement
Identify the solution set of the inequality.
Homework Equations
5x + 1 / x- 1 ≥ 7
The Attempt at a Solution
I multiplied both sides by x - 1 which gave me 5x+1 ≥ 7x - 7
Then I combined like terms together which gave me 8 ≥ 2x
I divided both sides by 2 which gave...
