<span>Let the number be x.
The quotient of negative 1 and the product of a number and 21 is -1/21x</span>
For the various values of X the values of Y are given as follows
X=-1; Y=3
X=0; Y=2
X=1; Y=3
X=2; Y=6
X=3; Y=11
Step-by-step explanation:
Step 1:
Let us consider the given expression as

Step 2:
Let us discuss the value of Y for the various values of X
If X = -1, Y = (-1)² + 2 = 3
If X = 0, Y = (0)² + 2 = 2
If X = 1, Y = (1)² + 2 = 3
If X = 2, Y = (2)² + 2 = 6
If X = 3, Y = (3)² + 2 = 11
Answer:
x = 2, x = -6
Step-by-step explanation:

Subtract 8 from both sides.

Simplify.

Solve with quadratic formula.
a = 1
b = 4
c = -12
I do not have time to show work for quadratic formula parts.
I am so sorry for this inconvenience.
Answer:
13 years old
Step-by-step explanation:
2x - 4
11-5=6
6 x 2 = 12
12 - 4 = 8
8 + 5 = 13
CHECKING JUST TO MAKE SURE:
13 - 5 = 8
11 - 5 = 6
6 x 2 = 12
12 - 8 = 4
You can now tell that it is correct.
