Answer: (-5,1)
Step-by-step explanation:
x=-2y-3
4y-x=9
4y-(-2y-3)=9
4y+2y+3=9
6y+3=9
6y=6
y=1
x=-2y-3
x=-2-3
x=-5
Answer:
Customer must pay a Total Amount of $240.
Step-by-step explanation:
Given:
Amount spent = $228
Sales tax = 5.25%
We need to find the Total Amount which need to be paid.
First we will find the amount paid in tax.
Amount paid in tax is equal to Percentage of sales tax multiplied with Amount spent and then divide by 100.
Framing the equation we get;
Amount paid in tax = 
Now Total Amount which need to be paid is equal to sum of Amount spent and Amount paid in tax.
Framing in equation form we get;
Total Amount which need to be paid = 
Rounding to nearest cent we get;
Total Amount which need to be paid = $240
Hence, Customer must pay a Total Amount of $240.

Answer:
x² - 4x + 3 = 0
Step-by-step explanation:
given roots x = a and x = b then the corresponding factors are
(x - a) and (x - b)
the equation is then the product of these factors , that is
(x - a)(x - b) = 0
given
roots x = 3 and x = 1 , then factors are (x - 3) and (x - 1) , then
(x - 3)(x - 1) = 0 ← expand factors using FOIL
x² - 4x + 3 = 0
