Answer:
Only the second equation is an identity
Step-by-step explanation:
<u>Note that </u>
<u>You can confirm it: </u>
<u>Therefore</u>
<h2>
It is not an Identity</h2>
<u>Let's the second one</u>
In this case, we already performed the calculations, so it is true. It is an Identity.
Answer:
x=1, y=2. (1, 2).
Step-by-step explanation:
-3x+10y=17
3x+7y=17
---------------
17y=34
y=34/17
y=2
3x+7(2)=17
3x+14=17
3x=17-14
3x=3
x=3/3
x=1
Answer:By 8(4)P.5, the slope of the line equally inclined to axes is tan(±45
o
)=±1. Hence by P+λQ=0,
5λ+3
2λ+4
=±1
⇒λ=
3
1
,−1. Putting for λ, the two lines are
x−y=0,x+y−2=0.
