Answer:
x = 0.36
Step-by-step explanation:
5x/3 + 2/5 = 1
5x/3 + 2/5 - 2/5 = 1 - 2/5
5x/3 × 3 = 0.6 × 3
5x = 1.8
5x ÷ 5 = 1.8 ÷ 5
x = 0.36
Answer:
1.6
Step-by-step explanation:
Lets count how many points are x and y away from each other since we dont have a graph.
X and Y points:
35-15=20
56-24=32
Use the formula:
32/20 = 1.6
In this problem, it will be helpful to know the vertex form of a parabola, which is listed below:
is a constant which helps to determine whether the parabola opens up or down. If
, then the parabola opens downward and if
, the parabola opens upwards
is the vertex of the parabola
By looking at the graph, we can first see that the graph opens downwards, meaning that . Thus, choices C and D are not valid. Now, let's use the vertex of the parabola to complete the equation.
The vertex of this parabola is (-1, 3), as shown by the graph. When we substitute this into our formula, we get:
The answer is a, .
