Answer:
expression for total cost is given by
Step-by-step explanation:
Here we need to find the expression for the total cost
Let us find the cost for x pounds of peanut , y pounds of cashews and z pounds of almonds
cost of 1 pound of peanut = $3.95
cost of x pounds of peanut = $3.95x
cost of 1 pound of cashews = $4.25
cost of y pounds of cashews = $4.25y
cost of 1 pounds of almonds = $5.99
cost of z pounds of almonds = $5.99z
total cost = 
cost after 20% off = total cost - 20% of total cost
= 80% of total cost
cost after 20% off =80%
cost after 20% off =
now we can plug x= 2 , y= 3 and z=1
so we have
cost after 20% off =
=$ 21.31
Step 1: simplify the equation by using the distributive property where applicable and combining like trems
Step 2: Collect all the variables on one side by either adding or subtracting.
step 3:Using inverse operations for addition and subtraction can removecontants ,toget the vaiables and constants on opposite sides.
Step 4:Inverse operations, such as multiplying and dividing can be used to eliminate coefficients in front of variables to get the variables by themselves

Proportional Relationships
A proportional relationship is one in which two quantities vary directly with each other. We say the variable y varies directly as x if:
y=kx
for some constant k , called the constant of proportionality .
(Some textbooks describe a proportional relationship by saying that " y varies proportionally with x " or that " y is directly proportional to x .")
This means that as x increases, y increases and as x decreases, y decreases-and that the ratio between them always stays the same.
The graph of the proportional relationship equation is a straight line through the origin.
ans C. the average temperature at the two resorts is about the same, but the range of temperature is different
Answer:
12. h=3
13. h=-3
Step-by-step explanation:
12. Recall that 
is a horizontal shift since h is being applied within the operation to the input. This means that h will slide the function left or right. Since the function f has a point at (1,-2) and g has the same point at (4,-2) then the function has moved 3 units 1+3=4 to the right. h=3.
13. Once again, h is a horizontal shift meaning the graphs has moved left or right only. Looking at g it has a point at (-2,2) while f has the same point at (1,2). So the graph f has moved to the left 3 units. This is h=-3 since 1+-3 = -2.
