Answer:
The coordinates of H′ are (-2,0).
Step-by-step explanation:
It is given that square EFGH stretches vertically by a factor of 2.5 with respect to the x-axis to create rectangle E′F′G′H′.
If a figure stretches vertically by a factor of 2.5 with respect to the x-axis, then the x-coordinates remains same and the points which lie on the axis are also remains the same after stretch.
It is given that the coordinates of H are (-2,0). This point lie on the x-axis, therefore it will remains the same after stretch.
Therefore the coordinates of H′ are (-2,0).
If you add them all together, you'd get 157. Then you divide by 7 and you'd get 31.4
If your asking what d equals, then it’s 10
Answer: The sum is 3.
Step-by-step explanation:
If we have a parabola, y = a*x^2 + b*x + c
We want to find the point (x, y) that corresponds to the vertex of that parabola.
The vertex of the parabola is at x value:
x = -b/2a
in this case
a = 1, b = 0, c = 3
then our vertex is at:
x = -0/2*1 = 0
Now we evaluate y(x) in this value and get:
y(0) = a*0^2 + 3 = 3
Then the vertex is at the point (0, 3)
the sum of the coordinates of the vertex is:
S = 0 + 3 = 3
