Simplify 4.3^2-7?
= 4 × 3^2 - 7
= 4 × 9 - 7
= 36 - 7
= 29

It is (positive) five. divide -1.25 by -0.25.
Answer:
Each side is going to be doubled in length considering the new one shows 24 cm where the original was 12 cm.
Step-by-step explanation:
Each side is going to be doubled in length considering the new one shows 24 cm where the original was 12 cm.
A) Look at the coordinates of the four dots:
(0,0) (150,50) (300,100) (450,150)
Divide the x's by the y's ( other than the (0,0) one:
150/50 = 3
300 / 100 = 3
450/150 = 3
The ratio is the same for all of them and the first set is (0,0) so it is a direct variation graph.
B) The constant of proportionality is the ratio found above by dividing the X values by the Y values, which is 3.
