This too pls pls pls

0.333n + 28 ; 33.3 ; $41.653

Step-by-step explanation:

For the best fit line :

The slope of the graph :

Drawing a right angled triangle at any point on the best fit line :

Gradient = (y2 - y1) / (x2 - x1)

Gradient = (45 - 30) / (50 - 5)

Gradient = 15 / 45

Gradient = 0.333

Intercept :

Where best fit line crosses the y - axis = 28

b = 0.333n + 28

The extra cost of each extra call made made is the slope of the graph :

$0.333 = 33.3 cents

Estimated cost of 41 calls

b = 0.333(41) + 28

b = $41.653

Kindly note that, the values used were obtained from a graph which isn't lined, therefore values taken may not be very accurate.

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1

5/12, or 5: 12
