Answer:
x1= -4
x2 = 4
Step-by-step explanation:
Set the equation equal to zero
x2 − 16 = 0
then
(x + 4)(x − 4) = 0
(x+4)= 0 which is equal to -4
and
(x-4)= 0 equals 4
Answer:
x = -1
y = -2
Step-by-step explanation:
To get y by itself:
3x - y = -1
-y = -1 - 3x
y = 1 + 3x
Solve for x with substitution:
2x = 4(1 + 3x) + 6
2x = 4 + 12x + 6
2x = 10 + 12x
-10x = 10
x = -1
Plug the x value into 3x - y = -1
3(-1) - y = -1
-3 - y = -1
-y = 2
y = -2

Answer:
1,716
Step-by-step explanation:
I just took the quiz.
Remember that percent means parts out of 100
x/100
discount is the decrease
so we divide the decrease by the original total and get
100/5775=0.0173
convert to fraction
0.0173/1
make bottom number 100
multiply by 100/100
1.73/100=1.73%
round
2%
