It would be the first one (x,-y) because say for example you take the point of v1 (4,-1) and reflect across x axis you get (4,1) for v
Answer:
I think its D)
Step-by-step explanation:
7x−3y+2=0
Add -7x to both sides.
7x−3y+2+−7x=0+−7x
−3y+2=−7x
Add -2 to both sides.
−3y+2+−2=−7x+−2
−3y=−7x−2
Divide both sides by -3.
−3y
/−3 = −7x−2
/−3
which equals d)
I also use this app to convert equations to slope-intercept and it showed me this
Answer: C is the correct answer Lines r and s and lines t and u must be parallel.
Step-by-step explanation: the step by step explanation is the the lines that answer C says are parallel
Lines r and s are crossed by lines t and u to form 16 angles. Clockwise from top left, at the intersection of r and t, the angles are 1, 2, 3, 4; at the intersection of s and t, 5, 6, 7, 8; at the intersection of u and s, 9, 10, 11, 12; at the intersection of u and r, 13, 14, 15, 16.
Answer:
B
Step-by-step explanation:
=3+(-7)
=3-7
As 3 is a positive number(+), it is referred as it gained yards. 7 is referred as lost yards because it's a negative number(-).
Hope this will help ya!
