Answer:
the 3rd bcoz you look so good on it and te backround aswell
Step-by-step explanation:
Let the numbers be a and b, then ab=0.2 and a/b=0.8, so a=0.8b. Therefore, 0.8b^2=0.2 and b^2=0.2/0.8=2/8=1/4 and b=+1/2 or +0.5 and a=+0.8*0.5=+<span>0.4. The two numbers are therefore 0.5 and 0.4 or -0.5 and -0.4. The quotient is 0.4/0.5</span>
<em>example</em><em>:</em>
<em>=</em>root (-2-1)*all powr 2*+(-1-5)*all power 2* =<em>3</em><em> </em><em>root</em><em> </em><em>5</em>
<em>then</em><em> </em><em>make</em><em> </em><em>all</em><em> </em><em>this</em><em> </em><em>stepes</em><em> </em><em>with</em><em> </em><em>RT</em><em> </em><em>and</em><em> </em><em>QT</em><em>.</em>

<em>w</em><em>e</em><em> </em><em>write</em><em> </em><em>under</em><em> </em><em>the</em><em> </em><em>root</em><em> </em><em>(</em><em>X</em><em>-</em><em>X</em><em>)</em><em>all</em><em> </em><em>power</em><em> </em><em>2</em><em> </em><em>then</em><em> </em><em> </em><em>(</em><em>y</em><em>-</em><em>y</em><em>)</em><em>all</em><em> </em><em>power</em><em> </em><em>2</em>
Answer:
12x+5
Step-by-step explanation:
If each ride is x dollars, and you want 12 tickets, 12 times x is 12x. Then you add the original upfront cost of $5.
Answer:
- y = -6
- x=2 and x=6
- Greatest value of y is y=2 and it occurs when x = 4
- For x between x = 2 and x = 6, y > 0
Step-by-step explanation:
<u>Definition</u>
- A parabola is a curve where any point is at an equal distance from:
a fixed point (the focus ), and
a fixed straight line (the directrix )
From the graph we can see that this is indeed so. We can even calculate the parabola equation from the given graph but since that is not required, I am not illustrating the steps here to do that
- The y-intercept is the value of y where the parabola cuts the y axis and from the graph we see that this occurs at y = -6
- The x-intercepts are the x-values where the parabola crosses the x-axis and we can see that this occurs at x = 2 and x = 6
- The greatest value of y occurs at the vertex of the parabola and we see that the vertex is at (4,2) ie greatest value of y is at y = 2 and occurs at x=4
- Between x =2 and x = 6 we see that the y values greater than 0 ie y > 0
(Note on last question: If you exclude these two points then y > 0 between x=2 and x=6.Specifically it is 0 at x =2 and x=6 and > 0. So if you include these two points then y ≥ 0. I have taken it as excluding the two points, x = 2 and x =6)
