Answer:
y = -4/5x + 2 & y = -2/7x - 4/7
Step-by-step explanation:
(4x) - 5y = -10 (2x) - 7y = 4
Move 4x on the same side as -10 Move 2x on the same side as 4
-5y = 4x -10 -7y = 2x + 4
Divide -5 to both sides Divide -7 by both sides
That should isolate the y for both equations.
4x/-5 = -4/5x....-10/-5 = 2 2x/-7 = -2/7x....4/-7 = -4/7
y = -4/5x + 2 y = -2/7x - 4/7
If that wasn't the answer to your question, I'm sorry.
But if it did, then your welcome.
Answer:
A. 12 and 43
Step-by-step explanation:
Pythagorean theorem is given as = 
Where, a and b are the two legs of the right triangle, while c is the hypotenuse/longest leg of the triangle.
In the figure given, the side of the largest square = the hypotenuse of the triangle = c
While the side of the other squares = a and b respectively, of the triangle.
Area of square = s², where s is the side length of the square.
Since we are given that the area of the largest square = 55, this is also equivalent to c² in the Pythagorean theorem.
The side length of the largest square = √55 ≈ 7.4 = c
Therefore, to determine the area of the other squares, check the options given if they add up to give 55.
Option A: 12 + 43 = 55
Option B: 14 + 40 = 54
Option C : 16 + 37 = 53.
The correct possible areas of the smaller squares would be A. 12 and 43.
