The slope is 1

Difference between the first and second y is 8
Difference between the first and second x is also 8

(8,8) simplifies to 1

Hope this helps!

Please crown;)

B) The perimeter of a squared field is 60 m. Find its area.

Pani-rosa [81]

$\qquad\qquad\huge\underline{{\sf Answer}}♨$

Let's solve ~

Perimeter of square is :

$\qquad \sf \dashrightarrow \:4 \times side \: length$

so, we can take side length as a, and solve for a ~

$\qquad \sf \dashrightarrow \:4a = 60$

$\qquad \sf \dashrightarrow \:a = 60 \div 4$

$\qquad \sf \dashrightarrow \:a = 15$

Now, since we know the side length. let's find Area of square :

$\qquad \sf \dashrightarrow \: {15}^{2}$

$\qquad \sf \dashrightarrow \:area = 225 \: m {}^{2}$

Please help me with this problemplssssssssssss

Answer:

The solution is: x = -5.2, y = 11.2

Step-by-step explanation:

We are given the following system of equations:

-7x-2y = 14

6x + 6y = 18

Simplifying the second equation by three, we have that:

x + y = 6

y = 6 - x.

Replacing in the first equation:

-7x - 2(6 - x) = 14

-7x - 12 + 2x = 14

-5x = 26

5x = -26

x = -5.2

y = 6 - x = 6 - (-5.2) = 6 + 5.2 = 11.2

The solution is: x = -5.2, y = 11.2

Whats the answer to this equation 10-4=9-[]

V125BC [204]

We can write this expression as 10 - 4 = 9 - x

10 - 4 = 9 - x

6 = 9 - x

6 - 9 = 9 - x - 9

-3 = -x

-3/-1 = -x/-1

3 = x

Hope This Helped! Good Luck!
