The easiest way to solve this equation is to convert feet into inches, so lets just say the painting is 27 inches by 41 inches.
Next multiply the two numbers 27*41=1107
Finally multiply 1107*.35= 387.45
The painting would cost $387.45
Answer:
D .For every day the soap is used, the predicted mass of the soap will decrease by 1.8 grams.
Step-by-step explanation:
The given regression equation is
Predicted y = 78.5 – 1.8x where, y = mass of a bar of soap in grams and x = number of days soap has been used.
Here, slope=b=-1.8.
Slope depicts the unit increase in predicted variable due to change in independent variable.
The given slope -1.8 shows that due to change in number of days soap is used the predicted mass of the soap decreases by 1.8 units. So, we can say that "For every day the soap is used, the predicted mass of the soap will decrease by 1.8 grams".
To start you would count 140 miles and 90 miles and add that together because they are at least that far apart because they are in different directions with the measurement starting at the airport. So you have 230 miles. Then you would know that plan A is 3 miles up and plane B is only 2 miles up, so there's one more mile between them. So you can add that and say 231 miles.
Answer:
2nd one : y = -4/x
3rd one : y + x/2 = 9
4th one
5th one : y = x^2
6th : 5.8x - y = 2.3
