Answer:
5. It's halfway between the x-intercepts.
Step-by-step explanation:
The vertex is halfway between the two x-intercepts when parabola is coordinate of the vertex. The points and x and y intercept crosses the x-axis vertically so that a u shaped lines are formed. The quadratic equation is used to find the points on the parabola.
Answer:
Now, the father is 60, and the son is 24.
Step-by-step explanation:
Now:
Father's age = f
Son's age = s
4 years ago:
Father's age = f - 4
Son's age = s - 4
In 12 years:
Father's age = f + 12
Son's age = s + 12
Now:
f = 3(s - 4)
In 12 years:
f + 12 = 2(s + 12)
We have 2 equations that we can solve in a system of equations.
f = 3(s - 4)
f + 12 = 2(s + 12)
f = 3s - 12
f + 12 = 2s + 24
f = 3s - 12
f = 2s + 12
Since above both equations are in terms of f, set the right sides equal and solve for s.
3s - 12 = 2s + 12
s = 24
f = 3(s - 4)
f = 3(24 - 4)
f = 3(20)
f = 60
Now, the father is 60, and the son is 24.
16, 36, 40
Set the problem up as 4x+9x+10x= 92
26x= 92
X= 4
Plug back in to get the lengths of the sides (shown above)
