Answer:
5
Step-by-step explanation:
4x-10=2x - Original equation
4x=2x+10 - Move constant to the right-hand side and change its sign
4x-2x=10 - Move variable to the left-hand side and change its sign
2x=10 - Combine like terms and divide both sides by 2
x=5 - Answer
Hope this helps!!!
Answer:
Step-by-step explanation:
Yes, because figure B can be obtained from figure A by a series of translations
Answer:
y - 4 = -(x - h)^2
Step-by-step explanation:
We begin with the stock function y = x^2. Its graph is a parabola with vertex at (0, 0) and opening up. The more general vertex form of the graph is
y - k = a(x - h)^2, where the point (h, k) is the vertex and 'a' determines the direction of opening as well as by how much the parabola is stretched vertically.
In this problem the vertex is (6, 4); that is, the vertex is shifted to the right by 6 units and upward from there by 4 units. The coefficient 'a' is -1, indicating that the graph opens downward.
So we have the equation y - 4 = -(x - h)^2. Without more information we cannot tell whether the graph is stretched vertically or not.
