Studentka2010 [4]

Based on our conversation above, we can then easily find the missing x-coordinate. If the equation for line BC is y = 6*x - 11 and we know that the y-coordinate is 13, then

13 = 6*x - 11
24 = 6*x
4 = x

The x-coordinate is 4.

HELP ASAP<br> What is the solution to the system of equations?<br> y = x + 3<br><br> y = -x-1

ASHA 777 [7]

Answer:

(A) Is right

Step-by-step explanation:

$y = x + 3 \\ y = - x - 1 \\ substitute \: y = - x - 1 \: in \: above \: eq \\ weget \\ - x - 1 = x + 3 \\ 2x = - 4\\ x = - 2 \\ \\$

put X= -2. in y = X+3

to get y 's value

Y = -2+3

= 1

therefore, your solution is ( -2,1)
