Step-by-step explanation:
your starting point is -9 so if you find one of your points multiply that by 5 and you have found your y axis
Answer:
5(6)+3(4.5)- 6(2)= 31.5
Step-by-step explanation:
Answer:
1) x+10
2) 1/2
Step-by-step explanation:
The side that measures 12 cm corresponds to the side that measures 3 cm.
The side that measures 16 cm corresponds to the side that measures 4 cm.
The ratio of the side lengths is (12 cm)/(3 cm) = (16 cm)/(4 cm) = 4
Now let's calculate the two areas.
For the 3 cm by 4 cm rectangle:
A = LW = 3 cm * 4 cm = 12 cm^2
For the 12 cm by 16 cm rectangle:
A = LW = 12 cm * 16 cm = 192 cm^2
The ratio of the areas is (192 cm^2)/(12 cm^2) = 16
The ratio of the areas is 16.
The ratio of side lengths is 4.
Notice that 16 = 4^2.
The ratio of the areas is the square of the ratio of the side lengths.
