Answer:
The probability of rolling a factor of 9 is 1/2, or 50%.
Step-by-step explanation:
The number 9's factors are 1, 3, and 9. Three of the six sides of the cube have a factor of 9. Therefore 3/6 of the sides are factors of nine.
Simplify 3/6 to 1/2 to get a probability of 50%.
Answer:
y=12
Step-by-step explanation:
y=2x ,so 2x=8x-x^2
x^2=8x-2x
x^2=6x
x^2/x=6x/x
x=6
y=2x ,2(6)
y=12

Answer:
D. (-2, 1).
Step-by-step explanation:
y = 3x + 7
y = -2x - 3
AS the expressions on the right are both equal to y:
3x + 7 = -2x - 3
3x + 2x = -3 - 7
5x = -10
x = -2
Plug this into the first equation:
y = 3(-2) + 7
y = 1.
