The ordered pairs of the solution to the system of equation are [(3, 6), (-3, 18)]
<h3>System of equations</h3>
Given the following system of equations expressed as:
f(x) = x² - 2x + 3 and f(x) = -2x + 12
Since they are both function of x, hence;
x² - 2x + 3 = -2x + 12
x² - 2x + 3 + 2x - 12 = 0
x² - 9 = 0
x² = 9
x = ±√9
x = ±3
If x = 3
f(x) = -2(3) + 12
f(x) = 6
If x = -3
f(x) = -2(-3) + 12
f(x) =18
Hence the ordered pairs of the solution to the system of equation are [(3, 6), (-3, 18)]

CALCULATE 5/8 + 3 1/4 x -3/6 - 2 5/12 = -3 5/12
Since the line is parallel, the same coefficients can be used for x and y. The constant on the right needs to change so that the given point will satisfy the equation.
... 5x - 4y = 5(-8) -4(2) = -40 -8 = -48
Your equation is
... 5x -4y = -48
Answer:
$331.25
Step-by-step explanation:
Given:
The jewelry center bought a pair of earrings for $250
They are going to mark the price of the earrings up 32.5%
Question asked:
How much will they sell the earrings for ?
Solution:
Cost price of a pair of earrings = $250
Mark up value = 32.5% of $250
= 
Now, we can find selling price of a pair of earring by simply adding the cost price and the mark up value.
Selling price = cost price + mark up value
= 250 + 81.25
= $331.25
Thus, they sell the earrings for $331.25
