Answer:
YES
Step-by-step explanation:
A rational number is a number that can be expressed as the quotient or fraction p/q of two integers
- 23 and 100 are both integers
- 23 / 100 = 0.23 which is not a continious decimal
You plug -x+16 in for y in x+4y=37 to get x after you multiply x+4y=37 by -1.
-x-4(-x+16)=-37
-x+4x-64=-37
3x-64=-37
3x=27
x=9
Then you plug 9 into either equation to get y.
y=-x+16
y=-(9)+16
y=7
x=9 and y=7
Answer:
x and (x - 6)
Step-by-step explanation:
y = a(x - h)² + k
h = 3 k = -2
y = a (x - 3)² -2
For point (0 , 0) on the function
0 = a (0 - 3)² -2
0 = 9a - 2
a = 2/9
a (x - 3)² -2 = 2/9 (x² - 6x + 9) - 2 = 2/9 * x * (x - 6) + 2 - 2 = 2/9 * x * (x-6)
Only cabinet with two silver coins is cabinet B.
The chance of choosing cabinet B is 1/3.
Thus, there is a 1/3 chance of the two cabinets contain 2 silver coins.
