Given the points A and B

The coordinates of point A = ( 3 , 1 )

The coordinates of point B = (-1 , -1)

The midpoint of AB, is the point C

C will be calculated as following :

C=\frac{A+B}{2}=\frac{(3,1)+(-1,-1)}{2}=\frac{(3-1,1-1)}{2}=\frac{(2,0)}{2}=(1,0)

so, the midpoint of AB = (1 , 0 )

3x + 5 = x - 3
dusya [7]

Answer:

x = -4

Step-by-step explanation:

3x + 5 = x - 3

Subtract x from each side

3x+5-x = x-3-x

2x+5 = -3

Subtract 5 from each side

2x+5-5 = -3-5

2x = -8

Divide each side by 2

2x/2 = -8/2

x = -4

Can someone plz answer B and C
Shkiper50 [21]

B. 
When two lines intersect they form two pairs of opposite angles.
Vertical angles are always congruent, which means that they are equal.
so  m<7 = m<8 or m<3y + 19 = m<5y-29


C. solve for y and measure <7 and <8

 3y + 19 = 5y-29
5y - 3y = 19+29
2y = 48
y = 24

so
5y-29 = 5(24) - 29 = 91
3y + 19 = 3(24) + 19 = 91

so <7 = 180 - 91 = 89
<7 = <8 = 89

PLEASE HELP!!!!!
Archy [21]
The first thing to do in this case is to perform the division and then compare with the simplified expression to determine the values of a, b, c and d.
 We have then:
 (12xy ^ 3 + 4x ^ 2y ^ 5) / (4xy ^ 2) =
 3x (1-1) and ^ (3-2) + x ^ (2-1) and ^ (5-2) =
 3x (0) and ^ (1) + x ^ (1) and ^ (3)
 Then, comparing with the simplified expression:
 3x ^ ay ^ b + 1x ^ cy ^ d
 The value of a is
 a = 0
 answer
 the value of a is 0
