M is the midpoint of line segment AB. If the coordinates of M are (2, 6) and the coordinates of B are (5, 10), which of the foll

timama [110]

Answer:

The coordinates of A would be (-1, 2)

Step-by-step explanation:

In order to find this, use the mid-point formula.

(xA + xB)/2 = xM

In this, the xA is the x value of point A, xB is the x value of point B, and xM is the x value of M. Now we plug in the known information and solve for xA.

(xA + 5)/2 = 2

xA + 5 = 4

xA = -1

Now we can do the same using the midpoint formula and the y values.

(yA + yB)/2 = yM

(yA + 10)/2 = 6

yA + 10 = 12

yA = 2

This gives us the midpoint of (-1, 2)

Find the quotient.<br><br>5 over 7 divided by 7 over 10

raketka [301]

Answer:

$\frac{5}{7}\div \frac{7}{10}=\frac{50}{49}$

Step-by-step explanation:

$\frac{5}{7}\div \frac{7}{10}$

$\mathrm{Apply\:the\:fraction\:rule}:\quad \frac{a}{b}\div \frac{c}{d}=\frac{a}{b}\times \frac{d}{c}$

$=\frac{5}{7}\times \frac{10}{7}$

$\mathrm{Multiply\:fractions}:\quad \frac{a}{b}\times \frac{c}{d}=\frac{a\:\times \:c}{b\:\times \:d}$

$=\frac{5\times \:10}{7\times \:7}$

$\mathrm{Multiply\:the\:numbers:}\:5\times \:10=50$

$=\frac{50}{7\times \:7}$

$\mathrm{Multiply\:the\:numbers:}\:7\times \:7=49$

$=\frac{50}{49}$

Therefore,

$\frac{5}{7}\div \frac{7}{10}=\frac{50}{49}$
