Answer:

5

Step-by-step explanation:

Slope (m) =

ΔY

ΔX

=

5

1

= 5

θ =

arctan( ΔY )

ΔX

= 78.69006752598°

ΔX = 1 – -3 = 4

ΔY = 2 – -18 = 20

Distance (d) = √ΔX2 + ΔY2 = √416 = 20.396078054371

Equation of the line:

y = 5x – 3

When x=0, y = -3

When y=0, x = 0.6

(new - original)/original = mark up

(78.08-64)/64= mark up

14.08/64 =mark up

.22 = mark up

Please help with this inequalities problem attached below.
Snezhnost [94]

Answer:

1) A. 5 + 2.75 * S ≤ 21

2) 5

Step-by-step explanation:

Well there is an initial price of $5 and $2.75 per stop, and she can only spend less than or equal to $21 we can make the following inequality,

5 + 2.75 * S ≤ 21,

<em>Meaning, Q.1 is A</em>

<em />

Now #2 is 5 stops because if we plug in 5 for s we get 18.75.

<em>Thus, the most amount of stops she can afford is 5.</em>

<em />

<em>Hope this helps :)</em>
