If x = −4 is a zero of the polynomial function f(x) = 2x3 + 13x2 + 23x + 12, which of the following is another zero of f(x)?  x
Talja [164]

Answer:

x= -1 is the another zero of the given function.  

Step-by-step explanation:

We have been given a function:

f(x)=2x^3+13x^2+23x+12

The zero of the function is that point where the function vanishes or the value of the function becomes zero.

From the given four values we will put the values in the function and wherever we get zero is the zero of the function.

put x= -1 we get:

f(-1)=2(-1)^3+13(-1)^2+23(-1)+12

f(-1)=-2+13-23+12=0

Hence, x= -1 is the another zero of the given function.

When Josh babysits, he chargers a flat fee of $14 plus an hourly rate of $9. How long would Josh need to babysit if he wants to
SpyIntel [72]

Answer:

\frac{36}{7}hours

Step-by-step explanation:

First let's get the flat fee of 14 out of the way, because he wants to earn 86 dollars and the 14 dollar fee is the y intercept.

86-14 = 72

We would then divide 72 by the slope (14 per hour) to see how many hours he has to work:

72/14 \approx5.14285714286

I would just simplify because this decimal isn't exact

72/14 = 36/7

So 36/7 hours
