Invert the divisor and then multiply 7/9 by your result:
7 -7 -49
--- * ------ = ---------
9 11 99
Kate: Please, for clarity, use " ^ " to denote exponentiation: 2x^2 + x − 4 = 0
And please include the instructions.
2x^2 + x − 4 = 0 can be re-written: 2(x^2 + (1/2)x - 2) = 0
Dividing both sides by 2 results in x^2 + (1/2)x - 2 = 0
Let's "complete the square:" x^2 + (1/2)x + (1/4)^2 - (1/4)^2 = 0
Then (x+(1/4))^2 = (1/4)^2
Taking the sqrt of both sides: x+1/4 = plus or minus 1/4
Solving for x: x = -1/4 plus or minus 1/4
Solving for x (continued): x = 0 and x = -1/2
I think what you are looking for is to indicate an ecuation for this. So lets do the procedure:
First you need to find the slope of this line.
<span>(5 - 6)/(5 + 1) = -1/6 </span>
<span>So, The slope of the perpendicular line is the opposite reciprocal, which is </span>
<span>+6/1.</span><span>Now we know the slope of the line but still have to find the mid point of the line. </span>
That is why we are going to <span>use the mid point equation </span>
<span>x = (-1 + 5)/2 = 2 </span>
<span>y = (6 + 5)/2 = 11/2 </span><span> </span>
<span>(y - 11/2) = 6(x - 2) </span>
<span>The last thing you do is rearrange the equation to get y = 6x - 6.5
Hope this is what you were looking for </span>
Answer: is there supposed to be a picture for it?
