Answer:
Vertex: (-2, 2)
Step-by-step explanation:
The x-coordinate of the vertex would be as follows;
x = -b/2a = 8/2(-2) = -8/4 = -2
respectively the y-coordinate of the vertex would be y(-2) = -2(-2)^2 - 8(-2) - 6 = -2(4) + 16 - 6 = - 8 + 10 = 2
Your vertex would be a maximum of (-2, 2)
* I say maximum as the coefficient of x^2 is -2, and it is less than zero so the parabola opens downward
Answer:
15 is a "coefficient" or "scalar multiple" or "constant multiplier"
Step-by-step explanation:
15y - 3 = 25
15 is the "coefficient of y"
the "-3" is a constant.
the "25" is a constant
Answer:
1x +3= T

Answer:

Step-by-step explanation:
The given equation is:

To find the point where this line intersect the y-axis, we put x=0 into the given equation.
When x=0, we have
.
This implies that; y=5.
The y-intercept is (0,5).
Comparing (0,5) to (0,b), we can conclude that; b=5
