If she read 52 pages in one hour, then she'll continue at a rate of 52 pages per hour.
Answer:
We can have two cases.
A quadratic function where the leading coefficient is larger than zero, in this case the arms of the graph will open up, and it will continue forever, so the maximum in this case is infinite.
A quadratic function where the leading coefficient is negative. In this case the arms of the graph will open down, then the maximum of the quadratic function coincides with the vertex of the function.
Where for a generic function:
y(x) = a*x^2 + b*x + c
The vertex is at:
x = -a/2b
and the maximum value is:
y(-a/2b)
Answer would be 35 as minus times minus is positive
Answer:
x=41
Step-by-step explanation:
x+x+2=-80
First add like terms: 2x+2=-80
Subtract 2 from 2 and -80.
2x=-80
Next divide 2 from both sides.
x=41
x+2=43
