8 is in the tenth position.

In order to round up, the number behind it (in this case. 9) must be one of the numbers of 5-9. Because 9 meets this requirement, you can round 8 to 9 and this will make 9 to 0.

Your answer is 490

Help please when I do the guadratic equation I’m doing something wrong
AnnZ [28]

Answer:

Graph A

Step-by-step explanation

The problem: y=2x^2+8x+3

1) You will need to determine the direction of the parabola, If a > 0 then the parabola opens upward, if a < 0 then the parabola opens downward.

2) If when doing this you get an imaginary solution, you would have no x intercepts. The first thing you need to do is find the x intercepts, you can do this by plugging in 0 for y, so this would give you 0=2x^2+8x+3. Once you have this you start by subtracting 3 from both sides, dividing 8 from both side, etc. (If you would like me to elaborate don't hesitate to ask!)

3) To find the graphs y intercept you plug in 0 for x, which gives you y=2(0)^2+8(0)+3, you do the same thing you did during the previous step for y. (Once again, I am willing to elaborate further if you need!)

4) You then need to find the vertex (h,k)

To find h: h= -b/2a

To find k: k = a(h)2 + b(h) + c

5) Once you've worked through this you can graph the point!

Hope this helped!

Maxwell House Coffee contains 13% Columbian coffee beans by volume while
user100 [1]

<em>x</em> kg of Maxwell House coffee contains 0.13<em>x</em> kg of Columbian beans.

<em>y</em> kg of Folgers contains 0.21<em>y</em> kg of beans.

You want a mixture weighing 70 kg, so

<em>x</em> + <em>y</em> = 70

You also want this blend to consist of 19% Columbian beans, or 0.19 (70 kg) = 13.3 kg, so

0.13<em>x</em> + 0.21<em>y</em> = 13.3

Solve for <em>x</em> and <em>y</em> :

<em>x</em> + <em>y</em> = 70   ===>   <em>y</em> = 70 - <em>x</em>

0.13<em>x</em> + 0.21<em>y</em> = 13.3   ===>   0.13<em>x</em> + 0.21 (70 - <em>x</em>) = 13.3

0.13<em>x</em> + 14.7 - 0.21<em>x</em> = 13.3

14.7 - 13.3 = 0.21<em>x</em> - 0.13<em>x</em>

1.4 = 0.08<em>x</em>

<em>x</em> = 17.5

<em>y</em> = 52.5
