The tax on the basket of watermelons is given by

Therefore, the total price Tiffany pays for the basket of watermelons is $9 + $0.81 = $9.81
Answer:
1000%
Step-by-step explanation:
c=10d,
3c will become 3*10d=30d
d is 10 times to c which converts to 1000%
The lines y=x+2 and y=x are parallel, because they have the same slope.
Answer:
The graph in the attached figure
Step-by-step explanation:
Let
x------> the number of times Emma mows the lawn
y------> the number of hours Emma babysits
we know that
------> inequality that represent the situation
The solution is the shade area above the solid line between the values of x and y positive
The equation of the solid line is equal to 
The slope of the line is negative 
The y-intercept of the line is the point
(value of y when the value of x is equal to zero)
The x-intercept of the line is the point
(value of x when the value of y is equal to zero)
so
The graph in the attached figure
