M = y2-y1/x2-x1
M = 3-10/7-4
M = -7/3
Step-by-step explanation:
x1 = -5, x2 =3 , y1 = -4 , y2=1
- formula = square foot of (x2 -x1)^2 + (y2 -y1)^2
- sqare root of (3 +5)^2 + (1 +4)^2
- square root of (8)^2 + (5)^2
- square root of 64 + 25
- square root of 89
- = 9.43
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.
Step-by-step explanation:
304
plug 4 in for x
3(4)^2 + 4(4)^3 = 304
48 + 256 = 304
