Graph the piecewise function (20 points!) (image provided below)
1 answer:
check the picture below.
notice, the hollow dot endpoints, is where the subfunction does not include that value of "x", and where the dot is a solid dot, that value is included in the subfunction.
so the piece-wise is simply the composition of all its subfunctions, in this case 3 subfunctions, within their range, notice the lines continue on the dashed line part, but that part is not included in the piece-wise because is outside the range provided for "x".

Answer: Brian gets $39.2 more over Colin.
Step-by-step explanation:
Given: Total tip amount = £78.40
The ratio of the share of tips for Pawl, Colin and Bria is 2:1 :5.
Let tip amount for Pawl = 2x, tip amount for Colin = x , tip amount for Bria = 5x
Then, 2x+x+5x= 78.40
Tip for Colin = $ 9.8 , Tip for Bria = 5($9.8)= $49
Difference = $(49-9.8) = $ 39.2
Hence, Brian gets $39.2 more over Colin.
