Step-by-step explanation:

A. part 1: $1.49 for 6 pencils

1 pencil would cost $1.49 / 6 = $0.24833(5s.f.) = $0.25 (nearest cent)

part 2: $4.60 for 20 pencils

1 pencil would cost $4.60 / 20 = $0.23

best value: part 2 (20pencil pack)

Which of the following is the graph of y=- square root x+1
maks197457 [2]

Answer:

The graph in the attached figure

Step-by-step explanation:

we have

y=-\sqrt{x+1}

Find the intercepts

<u>The y-intercept</u> is the value of y when the value of x is equal to zero

so

For x=0 -----> y=-\sqrt{0+1}=-1

The y-intercept is the point (0,-1)

<u>The x-intercept </u>is the value of x when the value of y is equal to zero

so

For y=0 -----> 0=-\sqrt{x+1} ----->x=-1

The x-intercept is the point (-1,0)

<em>Find the domain</em>

we know that

The radicand must be positive

so

x+1\geq0

x\geq-1

All real numbers greater than or equal to -1

The range is all real numbers less than or equal to -1

using a graphing tool

see the attached figure

Graph. y−2=23(x+4) Use the Line Tool and select two points to graph the equation. Use the slope and the point provided in the eq
sveticcg [70]

Answer:

See attached picture.

Step-by-step explanation:

The equation is in point slope form y - y_1 = m(x-x_1) where m is the slope and (x_1,y_1) is a point.

For the equation y-2 = 23(x+4), graph the point (-4,2). Then from this point count up 23 and over to the right 1.

This is the graph of the line.
