rusak2 [61]

Answer:

3. \displaystyle y = \frac{2}{5}x + 1\frac{2}{5}

2. \displaystyle y = -\frac{5}{7}x + 2

1. \displaystyle y = -2x + 4

Step-by-step explanation:

3. 2x - 5y = −7

- 2x - 2x

__________

\displaystyle \frac{-5y}{-5} = \frac{-2x - 7}{-5} \\ \\ y = \frac{2}{5}x + 1\frac{2}{5}

2. 5x + 7y = 14

- 5x - 5x

__________

\displaystyle \frac{7y}{7} = \frac{-5x + 14}{7} \\ \\ y = -\frac{5}{7}x + 2

1. 6x + 3y = 12

- 6x - 6x

__________

\displaystyle \frac{3y}{3} = \frac{-6x + 12}{3} \\ \\ y = -2x + 4

I am joyous to assist you anytime.

There are three squares inside the triangle . Find the area of the third triangle with steps , please
pogonyaev

Answer: 49 cm^2

Step-by-step explanation:

The length of the small pink square box will be:

L^2 = 9

L = sqrt( 9 )

L = 3

The length of the big pink square box will be:

L^2 = 16

L = sqrt( 16 )

L = 4

The length of the yellow square box will be:

4 + 3 = 7

The area of the third square box will be

A = 7^2

A = 49 cm^2
