WELL IN MATHEMATICAL TERMS IT WOULD BE 15.428
First we have to write these words in math. This now looks like 3x^2 = 15x. We can also write this as 3x^2 - 15x = 0. This looks like a quadratic, and it is! We can factor this quadratic into the product of two binomials, or (3x + 0)(x - 15).
In order to make (3x)(x - 15) equal to 0, either (3x) or (x-15) has to be equal to zero. This is because the product of a number and 0 always equals the number 0.
If 3x = 0, x needs to equal 0. But because x is a non zero number, x can't be zero.
Moving on to x-15 = 0, we see that x can equal 15. So the two possible values of x in our equation (3x)(x-15) are 0 and 15. We can eliminate 0 because x is a non zero number to get 15 as our final value for x.
Answer:
Substitution, but this system of equations has no solution.
Step-by-step explanation:
2x-4y=10
2y+6=x
----------------
2(2y+6)-4y=10
4y+12-4y=10
12=10
no solution.
Answer:
8.6667 or 8 4/6
Step-by-step explanation:
Answer:
Yes, no two ordered pairs in this list has the same second element.
Step-by-step explanation:
The function is a relation that associates to different elements and different elements and
Given K = {(-3, -3), (-4, -4), (-5, -5), (-6, -6)}
So,
Since different x have different image points y, this relation is the function. The correct answer is "Yes, no two ordered pairs in this list has the same second element."
