A.) Simplifying the equation would lead you to 15x^2-3x+9

b.) You know your answer is correct because you're adding the two polynomials together. 9x^2+6x^2 is 1tx^2. Now you have 2x-5x and since the negative is bigger, you get -3x. Then 5+4 is 9. You have no like terms therefore your answer is 15x^2-3x+9

6. Write the standard form of the line: y=2/5x-7
netineya [11]

The standard form for a linear equation is: ax + by + c = 0

Once we move all the variables and constants to one side, we get the standard form for a linear equation

y =  \frac{2}{5} x - 7\\y -\frac{2}{5}x = -7\\ y - \frac{2}{5}x + 7 = 0\\

Hope that helps!

Answer:

C. 75

Step-by-step explanation:

First, list the multiples of each numbers and stop when you reach the least common multiple (the smallest number the numbers can multiply up to):

5: 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75 . . .

25: 25, 50, 75 . . .

15: 15, 30, 45, 60, 75 . . .

5 times 15 is 75, 25 times 3 is 75, and 15 times 5 is 75. Their LCM is 75.
