The number of different types of drinks that a barista makes in one week is related to the cost of the drink. A collection of data on the cost of a particular drink and the number of that drink made over the course of the week is shown in the table below where x represents the cost of the drink in dollars and y represents the number of drinks made at each cost . Using a residual plot determine if the following model is a good fit for the data y= -11.5x + 120.45

Step-by-step explanation:

well it would be The answer would be A. 1 1/5

48/40 = 1 8/40

1 8/40 Simplify to 1 1/5

Hope this helps!

3.how is solving radical equations different than solving linear equations?

step-by-step explanation:

37/3

step-by-step explanation:

step 1: simplify both sides of the equation.

7x+8(x+

4

)=3(6x−9)−8

7x+(8)(x)+(8)(

1

4

)=(3)(6x)+(3)(−9)+−8(distribute)

7x+8x+2=18x+−27+−8

(7x+8x)+(2)=(18x)+(−27+−8)(combine like terms)

15x+2=18x+−35

15x+2=18x−35

tep 2: subtract 18x from both sides.

15x+2−18x=18x−35−18x

−3x+2=−35

step 3: subtract 2 from both sides.

−3x+2−2=−35−2

−3x=−37

step 4: divide both sides by -3.

−3x

−3

=
