Answer:

Yes, no verticle line passes through two graphed points

Step-by-step explanation:

A function is when 1 input only has 1 output. None of the inputs have different outputs. So, this is a function.

Aldos coffee shop makes a blend that is a mixture of two types of coffee. Type A coffee costs Aldo $5.80 per pound, and type of
LuckyWell [14K]
Let A represent amount of Type A coffee pounds used. 
Let B represent amount of Type B coffee pounds used

A + B = 156 
B = 156 - A 
A = 156 - B

5.80A + 4.65B = 826.60 
580 (156 - B) + 4.65B - 826.60 = 0 
904.8 - 5.80B + 4.65B - 826.60 = 0
904.8 - 1.15B - 826.60 = 0 
78.2 - 1.15B = 0 
78.2/1.15 = 1.15B/1.15
68 = B
B = 68 pounds of Type B coffee

There's many more steps you can take to check and etc but am too lazy to put down sorry.

What is the equation of the line best fit for the following data? Round the slope and y-intercept of the line to three decimal p
kari74 [83]

Answer:

y=1.383x-1.526

Step-by-step explanation:

The given data table is

x :        4       7       10       12       13

y :        5       7       12       14       18

We need to find the equation of the best fit line.

The general form of a best fit line is

y=mx+b         .... (1)

where, m is slope and b is y-intercept.

m=\frac{\sum_{i=1}^nx_iy_i-n\overline{x}\overline{y}}{\sum_{i=1}^nx_i^2-n\overline{x}^2}

b=\overline{y}-b\overline{x}

Using the graphing calculator we get

m=1.38321\approx 1.383

b=-1.52555\approx -1.526

Substitute m=1.383 and b=-1.526 in equation (1).

y=1.383x-1.526

Therefore, the equation of best fit line is y=1.383x-1.526.
