Describe how to solve d = rt for t
kotegsom [21]

Answer:

t = d/r

Step-by-step explanation:

Given the equation, d = rt for <em>t</em><em>:</em>

Switch sides:

rt = d

Divide both sides by r to isolate<em> t</em>:<em>  </em>

\frac{rt}{r} =  \frac{d}{r}

t = d/r

If √5 - x = 4,then x=<br>i need help on here how to solve it
Westkost [7]
Professor Dan Healy, one of my Engineering instructors back in prehistoric times,  had a favorite way of showing us how to do this kind of problem ... I mean the kind that's incredibly easy, but your own fear gets in the way and convinces you that you can't handle it.  Here is Prof. Healy's method.

For a few moments, call the square root of 5 by the name "cow".

cow - x = 4 .    Solve this equation for 'x' :

Add 'x' to each side of the equation:  cow = 4 + x

Subtract 4 from each side:                cow - 4 = x

Now, we can put the real value back in place of 'cow' :  <u>√5 - 4 = x</u>

That right there is a perfect solution.  But If you absolutely need to
know the number, then grab your calculator:

√5 = 2.2361 (rounded)

x = √5 - 4 = 2.2361 - 4 = <u>-1.7639</u> (rounded)

The slope of the line below is to use the corners of the labeled point to find a point slope equation of the line.
dexar [7]

Answer: Choice A)  y - 10 = 2(x - 3)

============================================================

Explanation:

We can rule out choices C and D because this diagonal line has a positive slope (as it moves uphill when moving to the right).

So m = 2 must be the slope.

---------

Recall that

y - y1 = m(x - x1)

represents the point slope form of a linear equation.

The point shown on this graph is (3,10) meaning that x1 = 3 and y1 = 10 pair up together.

So,

y - y1 = m(x - x1)

y - 10 = 2(x - 3)

which points to <u>choice A</u> as the final answer
