Is This Substitution?
Cause if it is, then Y = 3x - 4
Y = 4 + x
= (4, 8)
Answer:
use photomath and if that dont work use m a t h w a y
Step-by-step explanation:
Answer:
2x^2-16x+34
Step-by-step explanation:
Since Y is equal to -5
And you substitute -5 in the equation.
You now have -5=2x^2-16x+29
Add 5 to both sides
5-5=2x^-16x+29+5
It CAN'T equal 21, since 9+10=19
BUT, if the 9 was changed to like, 11 - Then it would = 21, or if the 10 was changed to a 12, it would make 21 also,
Mhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh
