Y=x2
Step-by-step explanation:
Answer:
Option 1 is correct.
Step-by-step explanation:
Given two linear equations to us are ,
And we have to find which system of linear equations have same answer .
On considering option (1) which is ,
On taking the second equation in this ,
This is same as the second one given in the Question . And the first one is already same .
<u>Hence</u><u> </u><u>option</u><u> </u><u>(</u><u>1</u><u>)</u><u> </u><u>is</u><u> </u><u>corre</u><u>ct</u><u> </u><u>.</u><u> </u>
Answer:
(2,6)
Step-by-step explanation:
Substitute y=3x into y=x+4 to get 3x=x+4. Solve for x.
x=2
Put x into either equation to get y=3(2) or y=(2)+4
y=6

(2x+8x2+3x−4x(x−4)(x−1)(20)x+4)(2)(x+4)(x−4)(2)x(x−1)(2)x(x+4)
=((2x+8x2+3x−4x(x−4)(x−1)(20)x+4)(2)(x+4)(x−4)(2)x(x−1)(2)x)(x+4)
=((2x+8x2+3x−4x(x−4)(x−1)(20)x+4)(2)(x+4)(x−4)(2)x(x−1)(2)x)(x)+((2x+8x2+3x−4x(x−4)(x−1)(20)x+4)(2)(x+4)(x−4)(2)x(x−1)(2)x)(4)
