J x j = j^2
j x -7 = -7j
7 x -7 = -49
j x 7 = 7j
j^2 - 7j + 7j - 49 = D = j^2 - 49

Trina's teacher asked her to explain the division problem 48 ÷ 12. Which choice gives the correct explanation?

saw5 [17]

Answer:

B). Break 48 into 4 groups of 12.

Step-by-step explanation:

Since 48 is divided by 12, you should break 48 into 12 different groups with 4 in each. All the other answer choices do not make sense because you cannot break 4 into 12 groups and get 48, same with 12.

Which expression is equivalent to y times y times y times z times z times z times z? y cubed z Superscript 4 12xy (y z) Superscr

Rina8888 [55]

Answer:

Option 1 - y cubed z superscript 4

Step-by-step explanation:

Given : Expression y times y times y times z times z times z times z.

To find : Which expression is equivalent to given expression ?

Solution :

Re-write the expression as,

$y \times y \times y \times z \times z \times z \times z$

Write the number of time value repeat itself as the power,

$y \times y \times y \times z \times z \times z \times z=y^3\times z^4$

$y \times y \times y \times z \times z \times z \times z=y^3z^4$

or we can say that the expression is y cubed z superscript 4.

Therefore, option 1 is correct.

M is the midpoint of AB and C is the midpoint of AM . Let the coordinate of A = 7y and the coordinate of B = 3x. Find the coordi

xz_007 [3.2K]

Answer:

The answer is below

Step-by-step explanation:

The coordinate of the midpoint of a line is gotten by adding the values of the two end points and then dividing the result by 2.

Given that M is the midpoint of AB, A = 7y and B = 3x, hence the coordinate of point M is given as:

M = (A + B)/2 = (7y + 3x)/2

Also, C is the midpoint of AM, hence the coordinates of point C is given as:

$C=\frac{A+M}{2}\\ \\C=\frac{7y+\frac{3x+7y}{2} }{2}\\ \\C=\frac{\frac{14y+3x+7y}{2} }{2}\\ \\C=\frac{21y+3x }{4}$

Hence the coordinates for point C is $C=\frac{21y+3x }{4}$
