Answer:
she was on a call for 36 minutes
Step-by-step explanation: 6.82-2.5= 4.32 4.32/.12= 36
Answer:
g = 3
Step-by-step explanation:
(x+7)(x-4) = x²+ gx -28
Multiply the two parenthesis
(x+7)(x-4)= x² -4x +7x -28
Combine like terms
(x+7)(x-4)= x²+3x-28
Compare the equations
x²+ gx -28 = x² +3x -28
g = 3
Remark
Watch out for the -4<=x<=6 thing. It causes lot's of problems if you are not careful.
Solution.
The second best answer is A and if that restriction, -4<=x<=6, wasn't there, the answer would be A.
When y = - 4, the x value falls outside the restricted domain ( -4<=x<=6) we have been given. so B is not the answer.
When x = - 4 you have to read straight down to see what the y value is. It is - 2. So this is your answer. Only exactly what is the answer. They ask for the minimum value and that is a y value in this case.
So the answer is C <<<<< Answer.
When y = 1 , x = - 2 1/2. That is within the domain, but it is not the minimum value so D is wrong.
