The point M is the bisector of the line RS

<h3>Bisector of a line</h3>

A bisector is a point or line that divides another line or segment into two equal parts

A line is the shortest distance between two points. From the line given, there are 3 points on the line which are R, M and S. Since the point M is located in the middle of RS, hence the point M is the bisector of the line RS

Which point lies on a circle that is centered at A(-3, 2) and passes through B(1, 3)?

My name is Ann [436]

The equation of a circle:
$(x-h)^2+(y-k)^2=r^2$
(h,k) - the coordinates of the center
r - the radius

$\hbox{the center: } A(-3,2) \\
h=-3 \\ k=2 \\ \\
\hbox{the equation:} \\
(x+3)^2+(y-2)^2=r^2 \\ \\
\hbox{the circle passes through B(1,3)} \\
x=1 \\ y=3 \\ \Downarrow \\
(1+3)^2+(3-2)^2=r^2 \\
4^2+1^2=r^2 \\
16+1=r^2 \\
17=r^2 \\ \\
\hbox{the equation is:} \\
(x+3)^2+(y-2)^2=17$

Plug the coordinates of the points into the equation and check:
$C(-1,-2) \\
(-1+3)^2+(-2-2)^2=17 \\
2^2+(-4)^2=17 \\
4+16=17 \\
20=17 \\
not \ true \\ \\
D(-6,3) \\
(-6+3)^2+(3-2)^2=17 \\
(-3)^2+1^2=17 \\
9+1=17 \\
10=17 \\
not \ true$

$E(-3,-3) \\
(-3+3)^2+(-3-2)^2=17 \\
0^2+(-5)^2=17 \\
25=17 \\
not \ true \\ \\
F(-2,6) \\
(-2+3)^2+(6-2)^2=17 \\
1^2+4^2=17 \\
1+16=17 \\
17=17 \\
true$

The answer is F(-2,6).

Which of these is a algebraic expression for five times the sum of two And Y?

andre [41]

Hey there!

The correct choice is D. 5(2 + y)

As you can see, the expression matches the description

5 times = 5( The parentheses directly next to the 5 means to multiply what is inside the parentheses by that number, in this case, 5

The sum of 2 and y = (2 + y)

Therefore, that makes D the CORRECT option

Hope this helps you!

God bless ❤️

How would I do this?

Answer:

A triangle is normally 180 degrees only.

Step-by-step explanation:

So, you have one 90 degree angle, and on 42.7 degree angle. Add those up to 132.7. Now, you would subtract that from 180, meaning that the answer is A, 47.3.

Good luck :DD
