Check if (1,6) is the solution to the system shown below

Andre45 [30]

Answer:

Step-by-step explanation:

To determine if (1, 6) is a solution, substitute x = 1, y = 6 into the left side of both equations and if the value obtained equals the right side then it is a solution.

10(1) - 6 = 10 - 6 = 4 ≠ - 6

- 10(1) + 5(6) = - 10 + 30 = 20 ≠ 30

Then (1, 6 ) is not a solution to the system

The polygons are similar. The area of one polygon is given. Find the area of the other polygon.

kap26 [50]

Answer:

90 cm²

Step-by-step explanation:

Given that both triangles are similar, it follows that the ratio of their area equals the square of their corresponding sides.

Let the area of the other triangle be x. Therefore:

$\frac{10}{x} = \frac{4^2}{12^2}$

$\frac{10}{x} = \frac{16}{144}$

Cross multiply

$10*144 = 16*x$

$1440 = 16x$

Divide both sides by 16

90 = x

Area of the other polygon = 90 cm²
