X(x+1) 1(x+4)
x^2+x+x+4
x^2+2x+4
The best definition for the term substitution would be...
the action of replacing someone or something with another person or thing.
1) true
2)false
Step-by-step explanation:
1) 5(3)+2(4) = 23
= 15+8=23
23=23
thus, (3,4) is solution for 5x + 2y = 23
2) 5(0)+2(4) =23
= 0+8 is not 23
thus, (0,4) is not solution for 5x + 2y = 23
For this you could name any positive number, 0, or -3,-2,-1.
ex.
2,3,-2
