Answer:
The pumpkin weight is 190.4 pounds
Step-by-step explanation:
We are trying to find the weight of the pumpkin
Let x be the weight of the pumpkin
We know the cost per pound = .45, the total cost 93.68 and the delivery fee =8
The total cost = the delivery fee plus the cost per pound * number of pounds
Substitute in what we know
93.68 = 8 + .45*w
Subtract 8 from each side
93.68-8 = 8-8 +.45w
85.68 = .45w
Divide each side by .45
85.68/.45 = .45w/.45
190.4 = w
The pumpkin weight is 190.4 pounds
Answer:
D. y=2x-2
Step-by-step explanation:
The format for the equation of a line is y=mx+b, where m is the slope and b is the y-intercept of the line.
The slope of this line is 2
The y-intercept of this line is -2
Therefore, the equation for this line should look like y=2x-2
