Answer:
Approximately 163 seconds (A)
Step-by-step explanation:
Line up 192 months on the x-axis with the line of best fit then run it across to the y-axis and it should be around 163 seconds.
The correct answer to your problem is B.
y-4 = 3(x-2)
We have that
<span>f(x) = x/4 -3
g(x)= 4x</span>²<span>+2x-4
find (f+g)( x)
step 1
adding the two functions together to create a new function.
[x/4 -3]+[4x²+2x-4]
step 2
making everything have a common denominator of 4 we get:
[(x-12+16x²+8x-16)]/4
step3
combine like terms in numerator
(16x²+9x-28)/4-----------> 4x²+(9/4)x-7
the answer is </span>4x²+(9/4)x-7
Answer:
C) 5.5 h
Step-by-step explanation:
Plug in the values
253.55 = 46.1 * t
Then solve for t by dividing both sides by 46.1 to get: C) 5.5 h
<em>The point where a function (for our problem its the cubic function shown)</em>
<u>and/or</u>
<em>is a zero of the function.</em>
From the graph shown, we can clearly see that it cuts the x-axis at -1 and touches the x-axis at 2.
So the zeros are at -1 and 2.
