The answer of the given equation is  -13y^{2} -11y+7

Step-by-step explanation:

The given equation can be written as,

(-8y^{2}+6y-1) +(-8y^{2}+8y+1)-(-3y^{2}+9y-9)

= -8y^{2} +6y-1-8y^{2}-8y -1+3y^{2}-9y+9

[Taking same powered variables together we get,]

=(-8y^{2}-8y^{2}+3y^{2}) +(6y-8y-9y)-1-1+9

= -13y^{2} -11y+7

Here the answer.

Select all statements that are true about the graph of ordered pair (5, −1) . The point is 5 units below the x-axis. The point i
seropon [69]
The -1 means that y = -1, so point is one unit below the x-axis.  In (5, -1), the x is positive, which could put the point in either the first quadrant or the fourth.  With the y being negative, however, it means that the point is in the fourth quadrant.  Those are your 2 true statements.

A taxicab charges $3.00 per person
Delicious77 [7]

Answer:

I believe the answer would be 20 miles max for one passenger.

Step-by-step explanation:

This is because if you create an equation out of this, knowing that only one passenger will be riding, you will get:

$3.00+$1.25x=$28       ($3 added too $1.25 times the number of miles (x) which equals the total amount you have ($28)).

x being the number of miles (so we need to calculate for x)

$3 + $1.25x = $28

-subtract 3 on both sides-

$1.25x=$28-$3

$1.25x=$25

-divide by 1.25 on both sides-

x=$25/$1.25

x=20 miles

Not sure if all calculations are correct, but I hope this helps :)!
