Answer:
Slope of line A is 1/3
Equation of Line B is y = 2x + 4
Answer:
a = -1/4
Step-by-step explanation:
Substitute the given solution into the equations
2x + y = 8
2(2a) + (9) = 8
4a + 9 = 8
Rearrange to get a alone
4a = 8 - 9
4a = -1
a = -1/4
2a = 2(-1/4) = -1/2
Solution = (-1/2, 9)
Answer: r≈ 9.99ft
Using the formula
C=2 π r
Solving for r
r= C/2π = 62.8/2·π ≈9.99493ft
Answer:
Step-by-step explanation:
An equation in the vertex form is written as
Where the point (h, k) is the vertex of the equation.
For an equation in the form the x coordinate of the vertex is defined as
In this case we have the equation .
Where
Then the x coordinate of the vertex is:
The y coordinate of the vertex is replacing the value of in the function
Then the vertex is:
Therefore The encuacion excrita in the form of vertice is:
To find the coefficient a we substitute a point that belongs to the function
The point (0, -1) belongs to the function. Thus.
<em>Then the written function in the form of vertice is</em>
