Answer:
x = y = - 1
Step-by-step explanation:
y = - 2x - 3
y = 7x + 6 -----> equation 1.
So,
7x + 6 = - 2x - 3
7x + 2x = - 3 - 6
9x = - 9
Divide 9 on both sides,
9x / 9 = - 9 / 9
x = - 1
Substitute x = - 1 in equation 1,
y = 7x + 6
= 7 ( - 1 ) + 6
= - 7 + 6
= 6 - 7
y = - 1
Therefore,
x = y = - 1
If you think about how 5 exponentially grows when you make the exponent larger, it gets easier. Since
is 25, and
is 125, then
must equal 625, right? Because 5*5*5*5=625. Hope I made sense!

<h2>
C. { HH, HT , TH, TT}</h2>
Step-by-step explanation:
Sample Space of any event E is the set of all possible outcomes whenever that event takes place.
Here, event E : Tossing 2 coins
Now, as we know, when an unbiased coin is tossed,
The total outcomes = {Head, Tail}
So, when two coins are flipped, the total outcomes are 2 x 2 = 4.
Sample space = { Head Head, Head Tail, Tail Head, Tail Tail}
or, S = { HH, HT , TH, TT}
