Answer:
Zeros: 1/3 and -1/3
Step-by-step explanation:
You can solve this for the zeros by using the factoring method:
p(x) = (-3x-1)(3x-1)
Then, you take each factored equation and set it equal to zero:
-3x-1=0
3x-1=0
Then, solve for zero:
-3x=1 x=-1/3
3x=1 x=1/3
Your zeros are 1/3 and -1/3.
Answer:
160 dollars
Step-by-step explanation:
So you would add 6.19 and 9.81 together. Then divide it by 2. You would get 8. Then multiply it by 20 and you would get 160 dollars
Given that the function f(x)=1/2x-6 was replaced with f(x+k)=1/2x-4, then the value of k we be as follows:
f(x)=1/2x-6
replacing x1=x+k
f(x+k)=1/2(x+k)-6
equating the above to 1/2x-4 we shall have:
1/2(x+k)-6=1/2x-4
simplifying we obtain:
1/2x+1/2k=1/2x-4
1/2k=-4
hence
k=-8
Answer:
$40
Step-by-step explanation:
If you were to purchase 7 picture frames, you would replace x in the equation with 7, this is shown below.
<u>f(x)=9x-23 ---> f(x)=9(7)-23</u>
Now we can solve for f(x). First start with 9(7).
<u>f(x)=9(7)-23 ---> f(x)=63-23</u>
Now finish the last part by subtracting 23 from 63.
<u>f(x)=63-23 ---> f(x)=40</u>
This means that you would have to pay $40 dollars to purchase the 7 picture frames.
First, you would multiply 12 by two. Then, when you get that answer, subtract 5 and you will find Greg's age.
Hope this helps!:)
