Answer:
{-12,0}
Step-by-step explanation:
first to solve this can collect like terms and add
X² +12x=0
and solve it by factorization method
X² +12x=0
x(x+12)=0
it means x multiplied by x = X² then x multiplied by 12 = 12x
so this means x or (x+12) equals to zero
x=0 and (x+12)=0
x+12=0
x=-12
so the solution set is {-12,0}
but can also be done by formula method
Answer:
undefined
Step-by-step explanation:
The x value does not change, which means it is a vertical line
Vertical lines have an undefined slope
we can check using
m = (y2-y1)/(x2-x1)
=(2- -2)/( -3 - -3)
= (2+2)/( -3+3)
4/0
undefined
Answer:
b and c
Step-by-step explanation:
looking at the markings
Answer:
(-3,-10)
Step-by-step explanation:
Given part a, you seem to know the midpoint formula. We can easily edit that to figure out what an endpoint is. Say that a variable "a" represents the x coordinate of D, and b the y coordinate. As the x coordinate of M is 0.5, and the x coordinate of C is 2, we can use the midpoint formula to say that 
. Multiplying both side by 2, we get that a+2=-1, and subtracting both sides by 2, a=-3. Similarly, 
, b+7=-3, and b=-10, making our answer (-3, -10). Let me know if you have any questions.
