Answer:
12 integers
Step-by-step explanation:
We want two-digit numbers, so let's provide two spaces:
__ __
In the first space, any of the four given numbers (1, 3, 5, and 9) can go there, so we have 4 numbers to choose from for that.
In the second space, because no digit can be repeated, we're only down to 3 possible choices. Think about it this way: if 1 was the first digit, then it can't be the second digit, so we now only have the numbers 3, 5, and 9 to put as the second digit; it's the same situation for any of the 4 numbers you put into the first digit place.
Now, multiply these two:
4 * 3 = 12
There are 12 such numbers.

Answer:
See answer below
Step-by-step explanation:
y + 2 = 2/3(x - 4)
y + 2 = 2/3x - 8/3
y = 2/3x - 8/3 - 2
y = 2/3x - 2 2/3 - 2
y = 2/3x - 4 2/3 or y = 2/3x - 14/3
Slope = 2/3
Answer:
Step-by-step explanation:
Let d and r be the diameter and radius, respectively.
d² + 12² = 15²
d² = 15² - 12² = 81
d = √81 = 9
r = d÷2 = 4.5 mm
