4(0.5x + 2.5y - 0.7y - 1.3y + 4)
multiply 4 by all in parentheses
(4*0.5x)+(4*2.5y)+(4*-7y)+(4*-1.3y)+(4*4
=2x+10y-28y-5.2y+16
combine like terms
=2x-23.2y+16
ANSWER:
Expression simplified 2x-23.2y+16
Hope this helps! :)
This question is incomplete.
Its 25 because she learned the 10 recipes in 2 weeks so 4 weeks is 20 and 5 weeks is 25 if its wrong some how than I'm tired so don't blame me
Answer:
The equation for total cost function is
C(x)=100+270x
Step-by-step explanation:
Variable cost per per board =total cost per day-fixed cost per day/daily output
total cost per day is $5,500
fixed cost per day is $100
20 boards are produced per day
variable cost per board=($5,500-$100)/20=$270 per day
Total cost C(x)=fixed cost per day+ variable per board*number of daily output
Since daily output is represented also by x ,total cost function is given thus:
C(x)=100+270x
Given:
3,6,9,12,15,18...
We need to find the difference.
The difference between 3 and 6 is 6-3 =3.
The difference between 6 and 9 is 9-6 =3.
The difference between 9 and 12 is 12-9 =3.
The difference between 12 and 15 is 15-12 =3.
The difference between 15 and 18 is 18-15 =3.
Recall that linear have equal differences.
We get an equal difference between each value.
The form of the equation is

Hence the given is linear.
