What are the zeros of the function g(x) = (x + 6) (x – 4)(x + 2) ?
vitfil [10]

9514 1404 393

Answer:

  x in {-6, -2, 4}

Step-by-step explanation:

The zero product rule tells you that a product will be zero if and only if one of the factors is zero. These binomial factors are zero when x has a value that is opposite the constant of the binomial.

  x +6 = 0   ⇒   x = -6

  x -4 = 0   ⇒   x = 4

  x +2 = 0   ⇒   x = -2

The zeros of the function are the x-values -6, -2, and 4.

A 100 rupee note was changed to 10 and 5 rupee notes, 15 notes in all. How many of each notes?​
san4es73 [151]

Answer:

Total number of notes is 11.

Step-by-step explanation:

Value is 100 rupees…

5x + 20y = 100 and x + y = 11 are the two equations.

We can simplify…

5x + 20 y - 5x - 5y = 100 - 55 = 45

15y = 45 so y = 3

x = 11 - y = 8

So, we have 8 notes of 5 rupees denomination and 3 notes of 20 rupees denomination.

I hope it helps you.

What is the domain of the function<br> f(x) = 5x+2?<br> XS-6<br> 0 x&gt;6<br> 0x&lt;6<br> O x&gt;-6
Sholpan [36]
I think your equation is wrong. the domain of f(x)= 5x+2 is ALL REAL NUMBERS. That means it’s negative infinity to positive infinity.
