Answer: Directix= -1
Focus (11, 2)
Step-by-step explanation:
If you subtract 2x from each side you get 5x-0.15=0.6 because the subtraction of 2x on the right of the equal sign cancels out. Then, if you add 0.15 to both sides you will get 5x=0.75. Finally, if you divide both sides by 5 you get x = 0.15.
X2+4x−5<span>5<span>x2</span>−8x+3</span>×<span><span>20x−12</span><span><span>x2</span>−6x−55</span></span>
start by doing some factoring
<span><span><span>(x+5)(x−1)</span><span>(x−1)(5x−3)</span></span>×<span><span>4(5x−3)</span><span>(x−11)(x+5)</span></span></span>
cancel common factors and then see whats left...
So you cancel (x+5) and 4(5x-3)?
