To find b you would be using the equation y=mx+b so to find be simply look at your equation and put your numbers in place so the answers so you would put your answers for the first one y=(m=-2)x(b=-3)
so easily the answers to these would be a=-3, b=-3 ,c=-4 ,d=-2
have a good night but definitly remeber the formula i told you for a test
Its (-10,-4) because when you graph it you get (-10,-4) straight through the orgin
Round to one decimal place
so you round the .8
look at the hundredth place and you see 6 so round up
38.9
Answer: 57.34
Step-by-step explanation:
Answer:
p=0.60w
Step-by-step explanation:
Let
p ----> the price of a watermelon in dollars
w ---> the weight of a watermelon in pounds
In this problem we have a proportional relationship
Remember that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form or
In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin
In this problem
p=kw
The value of the constant of proportionality k is the same that the unit rate
Find out the unit rate
Divide the total cost by the total weight
k=4.38/7.3=0.60per lb
substitute in the equation
p=0.60w
