Solve the equation for m. Show your work -40 - 6m + 1 = - 2
bekas [8.4K]

Answer:

\bold{m \ = \ \frac{-37}{6} \ Or  \ -6.16666666667}

Explanation:

-40 - 6m + 1 = - 2

  • Simplify Both Sides Of The Equation

−40 − 6m + 1 = −2

−40 + −6m + 1 = −2

(−6m) + (−40 + 1) = −2 (Combine Like Terms)

−6m + −39 = −2

= −6m − 39 = −2

  • Add 39 To Both Sides

−6m − 39 + 39 = −2 + 39

−6m = 37

  • Divide Both Sides By -6

-6m / -6 = 37 / -6

  • Simplify

\bold{m \ = \ \frac{-37}{6} \ Or  \ -6.16666666667}

A base ball diamond is square.The distance from home plate to first base is 90 feet.what is the distance from home plate to seco
Elena-2011 [213]

Because it is square, the distance from home to first base is the same as first base to second base.


Home to First is one side of a right triangle, first to second is the second side of the right triangle and then home to second base would be the hypotenuse of a right triangle.


Using the Pythagorean Theorem we can solve for the hypotenuse:

Let C = the hypotenuse:

90^2 + 90^2 = c^2

8100 + 8100 = c^2

16200 = c^2

c = √16200

c = 127.279 feet, round to 127 feet.

Graph the function y=<img src="https://tex.z-dn.net/?f=%5Csqrt%7Bx%7D%20-2-5" id="TexFormula1" title="\sqrt{x} -2-5" alt="\sqrt{
Rashid [163]

Answer:

(3, -4)

Step-by-step explanation:

The correct equation is:

y=\sqrt{x-2}-5

From the list of given points, we have to identify which point lies on the graph. This can be done by using the value of x-coordinates from the given points and see if they result in the corresponding y-coordinate:

For point (1, 4)

y=\sqrt{1-2}-5=\sqrt{-1}-5, This is not equal to 4, so it does not lie on the graph of given function.

For point (3, -4)

y=\sqrt{3-2}-5=\sqrt{1}-5=-4, The answer ans corresponding y-coordinate are the same. This means, (3, -4) point lies on the graph of given function.

Likewise, checking for 3rd and 4th point we find out that they do not lie on the graph.

So the correct answer is (3, -4)
