Subsitution
2y-x=5
minus 2y both sides
-x=5-2y
times -2 both sides
x=2y-5
subsitute 2y-5 for x in other equation
(2y-5)²+y²-25=0
expand
4y²-20y+25+y²-25=0
5y²-20y=0
factor
5y(y-4)=0
set to zero
5y=0
y=0
y-4=0
y=4
subsitute back
for y=0
x=2y-5
x=2(0)-5
x=-5
one solution is (-5,0)
for x=4
x=2y-5
x=2(4)-5
x=8-5
x=3
one solution is (3,4)
the 2 soltuions are (-5,0) and (3,4)
Answer:
The answer is 13/52 which is 25%.
Step-by-step explanation:
Mapping T'U'V'W' onto TUVW is just the backwards translations of TUVW to T'U'V'W'.
The translation (x + 3, y - 3) moves all x-coordinates 3 units to the right and all y-coordinates 3 units down.
So if we want to move the figure back to its original position, we do the opposite: move all x-coordinates 3 units to the <em>left</em> and y-coordinates 3 units <em>up</em>.
This is expressed as (x - 3, y + 3).
Each point (x, y) is also (domain, range), so the x-values are the domain and the y-values are the range. This answer is A
