From the graph, we can see that the graph has bumps on (0,25) and (5.1, -7) coordinates.
The higher point is (0,25) and lower one is at (5.1, -7).
We need to find to find the interval of the local minimum and value of local minimum.
<em>From the graph, we can see that graph has local minimum is -7 in the interval [4,7].</em>
Therefore, correct option is 4th option.
<h3>Over the interval [4,7], the local minimum is -7.</h3>
M equals 3x+21 because you add 2x+1x=3x.then you add 14+7=21.then you combine them together to get 3x+21
This is distributive property and to do distributive property, you distribute what is outside of the parenthesis to the numbers inside the parenthesis.
How-to-do:
2(8x-7)
2(8x) - 2(7)
16x-14
49-28=21
51-32=19
23x7=161
14x5=70
79.50 x .06 = 4.77
79.50 + 4.77 = $84.27
The total cost was $84.27
