First of all, we need to know what a function is.
A function is a binary relation between two sets that
Let z = 3x+2. Then, by substitution, your equation is
.. z^2 +7z -8 = 0
_____
This equation can be factored as
.. (z +8)(z -1) = 0
.. x = -8 or +1
Then
.. 3x +2 = -8 or +1
.. 3x = -10 or -1
.. x = -10/3 or -1/3
Simple interest is where 3% of the original value is added on each year
goal number = $102
original number = $680
3% of $680 can be found by getting 1% and multiplying by 3
100% = original number = $680
100% / 100 = 1% so $680 / 100 = $6.80 = 1%
3% = $6.80 * 3 = $20.40
so each year the money rises by $20.40
to find out how many years it would take to get to $102:
$102 / $20.40 = 5 years
Answer:
D (-3, 5)
Step-by-step explanation:
270 counter clockwise is the same as 90 clockwise.
For a 90° clockwise or 270° counter clockwise, take the opposite of the x coordinate then switch the coordinates.
(-5, -3) -----> (5, -3) ------> (-3, 5)
You can also rotate your screen 90° clockwise to see the new coordinates for A.
