Y=4 Because you divide 18 by 4.50 and then just put a point on positive four on your graph.

We are given x represent the number of pencils purchased, and let y represent the total cost.

We also given 18 pencils for $4.50.

Therefore, cost of each pencil = 4.50/18 = $0.25

Total cost (y) = cost of each pencil × number of pencils.

Therefore, equation would be

<h3>y = 0.25x.</h3>

In order to graph it, let us find some points for graph using table.

Plugging x=4, we get

y = 0.25(4) = 1.

Plugging x=8, we get

y = 0.25(8) = 2.

<h3>We got two coordinates, (4,1) and (8,2).</h3>

Plotting those points on the graph and joining the points.

We can see that graph represents the proportional relationship.

Determine the type and number of solutions of −4x^2 − 4x − 1 = 0
user100 [1]
The question is about types and number of soultions so you must use b^2-4ac which is the experssion under the root in the quadratic formula
so
if
b^2-4ac=0 then there is one real soultion
if
b^2-4ac<0 then there are two imaginary soultions that differ in the sign between them
if
b^2-4ac>0 then there are two real soultions
so a polynomial is written in the form
ax^2+bx+c=0
so a=-4
b=-4
c=-1
so b^2-4ac=16-16=0
so one real soultion is the answer you are looking
type:real
number:1

Answer:

1. (-6, -5) to (-5, -4)

2. (-3, -4) to (-1, -1)

Step-by-step explanation:

Increasing intervals include the x- and y- points increasing.

PS: I don't really know how to present the answer so if you're gonna submit it for a test or smth pls improve on the formatting yourself based on the question (So sorry I didn't really understand the question about writing a list of intervals and separating them with a comma :P)
