Answer:
(1, 2) and (-1, -2)
Step-by-step explanation:
Since y = 2x, the first blank tells you
2x = 2
x = 1
____
Since the variables are squared, a negative solution is as good as a positive solution, so x = -1 and y = -2 will also work.
When they say to solve for c, they just want you to isolate it. We can start by subtracting b from both sides to give us:
x - b = cd
After this, we can divide both sides by -d to finish isolating the variable c; remember that -cd is -1(c)(d):
= c
Therefore, c = 
Answer:
option D is your right answer
Step-by-step explanation:
have a nice day ^_^
D^2 = (x2-x1)^2 + (y2-y1)^2
D =sqrt((10+5)^2 + (10-2)^2)
D P SQRT(15^2 + 8^2)
D = sqrt(225 +64)
D= sqrt(289)
D = 17
The distance is 17
Answer:
x=16 y=38
Step-by-step explanation:
x+y=54.......equation 1
x=y-22........ equation 2
substitute
y-22+y=54
2y-22=54
2y=54+22
2y=76
y=76/2
y=38''
x=y-22
x=38-22
x=16''
