Answer: 65 degrees

Step-by-step explanation:

If you learned angles, you would know that m∠2 and m∠6 are corresponding angles since it was already given that a║b.

Reasoning: m∠2=m∠6; if m∠2=65, then m∠6=65 as well.

Have a nice day! :D

The midpoint of \overline{\text{AB}} AB is M(-3, -3)M(−3,−3). If the coordinates of AA are (-5, -1)(−5,−1), what are the coordin

astraxan [27]

The coordinates of point B are (-1,-5)

Step-by-step explanation:

The formula for mid-point is given by:

$M = (\frac{x_1+x_2}{2} , \frac{y_1+y_2}{2})$

Given

M(x,y) = (-3,-3)

A(x1,y1) = (-5, -1)

We have to find the coordinates of B(x2,y2)

So,

$M(x,y)= (\frac{x_1+x_2}{2} , \frac{y_1+y_2}{2})\\(-3,-3) = (\frac{-5+x_2}{2} , \frac{-1+y_2}{2})\\putting\ respective\ coordinates\ equal\\-3 = \frac{-5+x_2}{2}\\-3 * 2 = -5+x_2\\-6 = -5+x_2\\-6+5 = x_2\\x_2 = -1\\And\\-3 = \frac{-1+y_2}{2}\\-3*2 = -1+y_2\\-6 = -1+y_2\\-6+1 = y_2\\y_2 = -5$

Hence,

The coordinates of point B are (-1,-5)

Answer:

x = 18

Step-by-step explanation:

Add the opposite of the constant (-5), and multiply by the inverse of the coefficient of x (2/3).

$\dfrac{2}{3}x -5=7\\\\\dfrac{2}{3}x=12 \qquad\text{add 5}\\\\x=\dfrac{3}{2}\cdot 12 \qquad\text{multiply by $\dfrac{3}{2}$}\\\\ \boxed{x=18}$
