Answer:

Step-by-step explanation:

Solution,

For the midpoint of AB

x=\frac{x_1+x_2}{2} ,y=\frac{y_1+y_2}{2} \\\\x=\frac{1+3}{2} ,y=\frac{4+0}{2} \\\\x=2,y=2

Hence, co-ordinate of D is D(2,2)

For the midpoint of AC

x=\frac{x_1+x_2}{2} ,y=\frac{y_1+y_2}{2} \\\\x=\frac{1-3}{2} ,y=\frac{4-2}{2} \\\\x=-1,y=2

Hence coordinate of E is E(-1,2)

Now find the slope of DE and BC if they are equal they are parallel

The 20th expression would be 80. Counted on my fingers xD hit 80 when i did 20 fingers. which means that if you put 20 as n, it should come out to 80, but it comes out to 84 by the answer you chose, so I'm wondering if the answer you chose was right, or if it was A

Which statement about the system of equations is true?
vagabundo [1.1K]
8x + 6y = 10 ----------- (1)
5x - 3y = 2.2 ---------- (2)

(2) x 2:
10 x - 6y = 4.4 --------(2a)

(2a) + (1)
18x = 14.4
x = 1.8 ------- sub into (1)
8 (1.8) + 6y = 10
14.4 + 6y = 10
6y = 10 - 14.4
6y = - 4.4
y = - 0.73

There is 1 set of solution to it. (Answer C)
