Answer:
4% sales tax
Step-by-step explanation:
Take the original costs and subtract it from the price after sales tax.
$84.24-$81= $3.24
Divide 3.24 by 81
this gives you .04, now either multiply by 100 or move the decimal two places to the right to convert the decimal to a percentage.
Answer: B = (6,-8)
Step-by-step explanation:
first the midpoint formula is 
then you take the x co-ordinate of A and substitute it into one of the x values in the first part of the formula:
then solve it like an equation:
then you take the y co-ordinate of A and substitute it into one of the y values in the second part of the midpoint formula:
then solve it like an equation:
∴ the answer is x=6, y= -8
which is expressed as a point, B(6,-8)
Hello,
{x=y-3
{x+3y=13;
{x=y-3
{y-3+3y=13;
{x=y-3
{4y=13+3;
{x=y-3
{4y=16;
{x=y-3
{y=16:4=4;
{x=4-3=1
{y=4;
{x=1
{y=4
the solution to the system of equations is (1,4)
Bye :-)
First, you expand it.
2x - 6x + 3 = 3 - 4x
Now, simplify.
-4x + 3 = - 4x
Cancel out the double "4x"
3 = 3
Since both side have an equal answer, there in an infinite number of answers.
Hope this helps! ☺♥
