Tell whether the side lengths 3, 9, and 15 form a triangle. answers: No, because 9 + 3 isn’t greater than 15. Yes, because 15 + 9 is greater than 3. Yes, because the sum of any two sides is greater than 30. No, because 15 + 9 isn’t less than 3.

The answer is no, because 9 + 3 isn't greater than 15. Remember, to form a triangle the sum of the 2 shortest sides must be greater than the longest side.

No, because 9 + 3 isn't greater than 15.

Step-by-step explanation:

The Triangle Inequality Theorem states that the 2 shorter legs of a triangle's sum must add up to be greater than the hypotenuse or the longest side. So 3, 9, and 15 don't make a triangle.

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.

f(x)=2/3x-8, which give g(x) the greatest value.
