Answer:
<h2>The number of the books is 4384.</h2>
Step-by-step explanation:
Let, the number of the books will be x.
With the first method, the total cost will be, $(19521 + 21x) and with the second method, the total cost will be $(62265 + 11.25x).
As per the given condition it is told that the costing should be equal.
Hence, 
.
Answer:
Axis of Symmetry is x = 2
Vertex is (2, -9)
X Intercepts are (5, 0) and (-1, 0)
Step-by-step explanation:
Quadratic Equation is in standard form. Formula find the x value of the vertex in standard form is -b/2a
a=1
b=-4
c=-5
--4/2(1) = 2
Plugin to find the y value of the vertex.
2^2-4(2)-5=y
4-8-5=y
y = -9
The x value of the vertex (in this case is 2) is the axis of symmetry. Therefore the axis of symmetry is x=2
Factor the equation to put into intercept form.
(x-5)(x+1) = y
The equation can be FOIL-ed to get back to standard form.
Separate the 2 parentheses and whatever can cancel the parentheses are your intercepts.
For (x-5) your intercept is (5, 0)
For (x+1) your intercept is (-1, 0)
The x intercepts are where the parabola will cross the x axis on the graph.
The correct answer is C) the function represented by the graph has a steeper slope and the function represented by the equation has a larger y-intercept.
The equation is written in slope-intercept form, y=mx+b. m is the slope and b is the y-intercept. In this function, the slope is 2 and the y-intercept is 2.
Looking at the graph, the y-intercept is 1. Going from the y-intercept, if we go up 2, it does not go over quite 1 unit. Therefore the slope is steeper on the graph.
The answer is going to be D
Answer:
5y^2(4y^4 - 3y^2 +8)
Step-by-step explanation:
20y^6 - 15y^4 + 40y^2
5y^2(4y^4 - 3y^2 +8)
