Jan is enlarging the sketch shown on a photocopier. which could be the dimensions of her enlargement?

the figure shows a rectangle. the horizontal length of the rectangle is labeled as 3 inches and the vertical length of the rectangle is labeled as 2 inches.

a.
4 inches × 5 inches

b.
5 inches × 6 inches

c.
7 inches × 10.5 inches

d.
8 inches × 9 inches

C. 7 inches × 10.5 inches

Step-by-step explanation:

Jan is enlarging the sketch shown on a photocopier. The figure shows a rectangle  3 inches long and  2 inches wide.

Hie enlarged rectangle must be similar to the given one. Similar rectangles have propotional sides, so

the width of the new rectangle = 2x inches

the length of the new rectangle = 3x inches.

Check all options:

A. If 2x = 4, then x = 2 and 3x = 6 - false

B. If 2x = 5, then x = 2.5 and 3x = 7.5 - false

C. If 2x = 7, then x= 3.5 amd 3x = 10.5 - true

D. If 2x = 8, then x = 4 and 3x = 12 - false

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
