Answer:
18.02
Step-by-step explanation:
Answer:
186 and 187
Step-by-step explanation:
Let n be the first integer.
Then n+1 is the next integer.
We are given their sum is 373.
n+(n+1)=373
Combine like terms:
2n+1=373
Subtract 1 on both sides:
2n=372
Divide both sides by 2:
n=186
So n+1=187.
187

use substitution method by using the x into for each equation.
Answer:
The vertex of the graph is:
- the minimum point for a parabola that opens upwards
- the maximum point for a parabola that opens downwards
As this parabola opens upwards, the vertex is the minimum point.
From inspection of the graph, vertex = (-3, -1)
<u>Equation of the graph</u>
From inspection we can see that the x-intercepts are when
x = -4 and x = -2
