First you write out your equation, which is 28x-42=154. Then you solve you equation. First, add 42 to each side, get 28x=196. Divide both sides by 28, get x=7.
Answer:

Step-by-step explanation:
We have:

And we want to find the value of x such that the expression is positive. So, we can write this as the following inequality:

Solve for the inequality. First, we can solve for the zeros like a normal quadratic. So, pretend the inequality is with an equal sign:

Zero Product Property:

On the left, subtract 5.
On the right, add 1.
So, our zeros are:

Since our inequality is a <em>greater than</em>, our answer is an "or" inequality with our answer being all the values to the <em>left</em> of our lesser zero and all the values to the <em>right </em>of our greater zero.
So, our solution is:

And we're done!
Answer:

Step-by-step explanation:
The slope-intercept form of an equation of a line:

<em>m</em><em> - slope</em>
<em>b</em><em> - y-intercept</em>
<em />
We have

Substitute:

I hope this helps I took both of the points and used the slope formula to get my slope which is 7/10 then I took any point from those two then I plugged it in to get the point slope form
Answer: y-3=7/10(x-6)
Answer:
Well, I'm not sure what you mean but Ptolemy's Theorem gives a relationship between the side lengths and the diagonals of a cyclic quadrilateral; it is the equality case of Ptolemy's Inequality. Ptolemy's Theorem frequently shows up as an intermediate step in problems involving inscribed figures.
