Answer:
{r,z}
Step-by-step explanation:
U = {r,s,t,u,v,w,x,y,z}
P = {s,t,u,v,w}
Q = {u,v,x,y}
P' means elements in the universe,U, that are not in P.
P'={r,x,y,z}.
Q' means elements in the universe,U, that are not in Q.
Q'={r,s,t,w,z}.
P' intersect Q' means what elements are in common in both lists.
{r,z}
<span>You do need the slope. It's not obvious in "Standard Form".
Ax + By = C ==> y = -(A/B)x + (C/B)
There's your slope to compare. Find -A/B for each.
3x + 2y = 4 ==> Slope = -3/2
6x + 4y = 5 ==> Slope = -6/4 = -3/2
3x + y = 4 ==> Slope = -3
The top two examples COULD be parallel. If the constant is the same, that's a bit sneaky because they are really the SAME line. That's not really parallel.</span>
Answer:
The sum of all the angles of any triangle is 180°
So, 180 - (53 + 48) = 180 - 101 = 79
<SRT = 79°
Answer:(-4,0)
Step-by-step explanation:
Given
Point A (6,-4)
Reflection of Point A about line y=-2 is
A' (6,0)
If any Point is reflected about any line y=constant then its x coordinate remains same
Now reflection of Point A' about x=1 is
A'' (-4,0)
If any point is reflected about line x=constant then its y coordinate remains same
