These figures are similiar. the area of one is given. find the area of the other

18 in²

Step-by-step explanation:

Given 2 similar figures then

linear ratio = 9 : 12 = 3 : 4

area ratio = 3² : 4² = 9 : 16

let the area of the other figure be x

= [ ]

cross- multiply

16x = 288 ( divide both sides by 16 )

x = 18

Area of other figure is 18 in²

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571

step-by-step explanation:

the equation is not included but the answer is (1.50, 2.00, 2.75)
