the equation is a quadratic one, and it has a positive coefficient on the leading term, meaning, is opening upwards, so it has a "burrow" for the vertex.
the minimum or lowest point for a quadratic opening upwards is, well, the vertex point :), the "x" value is the year, the "y" or f(x) value is the population, we're asked for the year, or the x-coordinate of the vertex
well
Answer:
x= 70
Step-by-step explanation:
The equation is: x/7-12= -2
First, do inverse operations. Do = +12 on each side to get rid of 12
Now: x/7=10
Multiply 7 on each side
Now: x=70
Hope this helped!!! :D
Answer:
900
Step-by-step explanation:
(n-2)*180
5*180=900
Let, that number = x
It would be: x * 0.65 = 52
x = 52 / 0.65
x = 80
So, that number and your answer is 80
Hope this helps!
The coordinate of point V is at (-16, 9)
If Point T(-9,5) lies on the perpendicular bisector of UV, this means that the point divides the line UV into two equal parts
Given the following coordinates
Midpoint T = (-9, 5)
U = (-2, 1)
Required
coordinate of point V
Using the midpoint formulas;
Get the value if x₂ and y₂
Similarly;
Hence the coordinate of point V is at (-16, 9)
