Answer:

y=\frac{4}{3}x+7

Step-by-step explanation:

y=-\frac{3}{4}x+1

Points: (12, 9)

Slope (m⊥): \frac{4}{3}

y=\frac{4}{3}x+b

9 = \frac{4}{3}(12)+b

9 = 16 + b

b = 7

y=\frac{4}{3}x+7

The combined area of two squares is 80 square centimeters. Each side of one square is twice as long as a side of the other squar
o-na [289]

The length of each side of the larger square is 8 cm.

<u>Step-by-step explanation</u>:

Step 1 ;

  • The combined area of two squares = 80 sq.cm
  • The side of small square = x
  • The side of larger square = 2x

Step 2 :

Area of the square = a^2

Area of small square + area of large square = 80

x^2 + (2x)^2 = 80

x^2 + 4x^2 = 80

5x^2 = 80

x^2 = 80/5

x^2 = 16

x = ±4

Step 3 :

Since length cannot be negative, the value of x= 4

∴ The length of the side of small square = 4cm

The length of the side of larger square = 2x = 8cm
