Answer:
A. 49 + 16 (t - 1)
Step-by-step explanation:
Plug in t = 1 to test for the first hour:

Test as many values as you like, but testing t = 5:

You can see that plugging in just a few values confirms the answer.
 
        
             
        
        
        
Answer:

Step-by-step explanation:
The input it taken as the unknown base value, while the output here is the area of the trapezoid. b is therefore the base value, and A( b ) is the area of the trapezoid. Let's formulate the equation for the area of the trapezoid, and isolate the area of the trapezoid. To find the inverse of this function, switch y ( this is A( b ) ) and b, solving for y once more, y ➡ y ⁻ ¹.
y = height  ( ( unknown base value ( b ) + 7 ) / 2 ),
 ( ( unknown base value ( b ) + 7 ) / 2 ),
y = 10  ( ( b + 7 ) / 2 )
 ( ( b + 7 ) / 2 )
Now switch the positions of y and b -
b = 10  ( ( y + 7 ) / 2 ) or
 ( ( y + 7 ) / 2 ) or  - now that we are going to take the inverse ( y ⁻ ¹ ) or B( a ), b will now be changed to a,
 - now that we are going to take the inverse ( y ⁻ ¹ ) or B( a ), b will now be changed to a, 
 ,
,
 
 
Therefore the equation that represents the inverse function will be the following : B(a) = a / 5 - 7
 
        
             
        
        
        
Answer:
Multiply the top equation by -3 and the bottom equation by 2
Step-by-step explanation:
Given <u>system of equations</u>:

To solve the given system of equations by addition, make one of the variables in both equations <u>sum to zero</u>.  To do this, the chosen variable must have the <u>same coefficient</u>, but it should be <u>negative</u> in one equation and <u>positive</u> in the other, so that when the two equations are added together, the variable is <u>eliminated</u>.
<u>To eliminate the </u><u>variable y</u>:
Multiply the top equation by -3 to make the coefficient of the y variable 6:

Multiply the bottom equation by 2 to make the coefficient of the y variable -6:

Add the two equations together to <u>eliminate y</u>:

<u>Solve</u> for x:


<u>Substitute</u> the found value of x into one of the equations and <u>solve for y</u>:
