Mr. porter owns a house. when he first bought the house it was valued at d dollars. since then, the value of the house has increased. mr. porter writes the equation below to express the current value of his house.

d+0.21d=1.21d

mr. porter claims that the value of his house has increased by 121%, since 1.21 is equal to 121%.

decide if mr. porter is correct. if he is correct, enter 121 below. if he is not correct, enter the correct percent increase.

answer:

what is your question that you ask

step-by-step explanation:

when rotating a figure 180 degrees, imagine that you are able to take the figure and turn it clockwise or counterclockwise around a center point. to rotate a figure 180 degrees, you will need to apply the rule (x, y) → (-x, -y). start by using a coordinate grid with coordinates for each vertex of the figure. the center point of the coordinate grid is located at (0, 0), which is what you will rotate the figure around. write down the original coordinates of the shape you are going to rotate. then, apply the rule. for example, coordinate (1, 2) becomes (-1, -2). another example would be, coordinate (-4, -2) becoming (4, 2). after you change each original coordinate to the rotated coordinate, you will draw your new figure.
