Answer:
Step-by-step explanation:
Given
--- The variation
Required
Determine the constant of proportionality (k)
Express as an equation
Multiply both sides by 
Make k the subject
Given that:
We have:
This can be represented as:
10 4/10 or 10 2/5 if you reduce it
Answer:
Equation is Y=mx+c (that's how I know it, it may differ)
Step-by-step explanation:
First get the slope which is M and you just gotta do the second y - the first y from the brackets and divide them by the second x - the first x
6-1 /-2-3 = 5/-5
= -1
So now u gotta find c, C= Y-mx
And u have got two brackets, which have an x and y, and u now have m.
Pick one of the brackets like (-2,6) and put them in the equation so it will be : C =6+1*-2
So C =4
The equation now is : Y = - 1x + 4
Answer:
CT= $950
Step-by-step explanation:
Dado la siguiente información:
Servicio= $300 primeros dos
Servicio adicional= $150
Descuento= $100
<u>Para calculate el costo total, tenemos que usar la siguiente formula:</u>
CT= 300x + 150y - 100
x= costo normal
y= costo promocional
CT= 300*2 + 150*3 - 100
CT= $950
N = 20 then when you add 7 it becomes 27 :) have a good day
