Answer:

one solution (0,-1)

Step-by-step explanation:

y=5x-1

-15x-3y=3

LEts solve for x  and y, Substitute  5x-1 for y in second equation

-15x-3y=3

-15x-3(5x-1)=3

-15x-15x+3=3

Combine like terms

-30x+3=3

Subtract 3 on both sides

-30x=0

Divide both sides by -30

x=0

Now plug in 0 for x in first equation

y=5x-1

y=5(0)-1=-1

So one solution (0,-1)

Answer:

<em>The second figure ( rectangle ) has a longer length of it's diagonal comparative to the first figure ( square )</em>

Step-by-step explanation:

We can't confirm the length of these diagonals based on the appearance of the figure, so let us apply Pythagorean Theorem;

This diagonal divides each figure ( square + rectangle ) into two congruent, right angle triangles ⇒ from which we may apply Pythagorean Theorem, where the diagonal acts as the hypotenuse;

5^2 + 5^2 = x^2 ⇒ x is the length of the diagonal,

25 + 25 = x^2,

x^2 = 50,

x = √50

Now the same procedure can be applied to this other quadrilateral;

3^2 + 7^2 = x^2 ⇒ x is the length of the diagonal,

9 + 49 = x^2,

x^2 = 58,

x = √58

<em>Therefore the second figure ( rectangle ) has a longer length of it's diagonal comparative to the first figure ( square )</em>

If he counts 76 feet, that means there’s 38 animals in total, because animals have 2 feet. 76/2=38
