What is the value of m in the equation 5m − 7 = 6m + 11?<br><br> A.18<br> B. 1<br> C. −18<br> D.−1
adoni [48]
Hello there ^ _ ^

5m - 7 = 6m + 11
Solve for M
5m - 6m = 11+ 7
-m = 18
Divide both sides by -1
-m/-1 = 18/-1
m = -18

Good luck!

Dexter has 83 tiles left over from tiling his bathroom floor and he would like to use them to tile the front entrance of his hou
creativ13 [48]

Answer: [0, 396]

Step-by-step explanation:

The domain is the acceptable values of x in the function.  In this case, x = t, the number of tiles.  If you think about it, the minimum number of tiles is 0 (you can't have a negative number of tiles), and the maximum number of tiles is 44 (you only have 44 tiles).  So, the domain for this function is from 0 to 44.

0 to 44 written in interval notation is [0,44].

The range is the acceptable values of y in the function.  In this case, y = A, the area given.  A(t) = 9t, so you can use the acceptable values of t to get the range.  Again, the minimum area is 0 because you can't have negative area. To find the maximum area, plug in the maximum number of tiles: 9.

A(t) = 9t

A = 9(44)

A = 396

With the maximum number of tiles, 44, the area you get is 396 cm².  Therefore, the acceptable values of A are from 0 to 396.

0 to 396 written in interval notation is [0, 396].

Fill in the missing term in the equation
Y_Kistochka [10]

Answer:

<u>x</u>

Step-by-step explanation:

Let's simplify the LHS so it can be equated to the RHS.

\frac{x}{x^{2} -4x+4} - \frac{x}{x^{2} -3x+2}

\frac{x}{(x-2)^{2} } - \frac{x}{(x-1)(x-2)}

\frac{x(x-1)-x(x-2)}{(x-2)^{2}(x-1)}

\frac{x^{2} -x-x^{2}+2x }{(x-2)^{2}(x-1)}

\frac{x}{(x-2)^{2}(x-1)}

Hence, the missing term in the numerator of the answer is <u>x</u>
