4 0

Answer:

(-3,8)

Step-by-step explanation:

7x+5y=19

y=8

Because we know y=8 we cane use 8 instead of y in the first equation.

   1) 7x+5(8)=19

   2) 7x+40=19

   3) 7x=-21

   4) x=-3

Checking the work)

   1) 7(-3)+5(8)=19

   2) -21+40=19

   3) 19=19

A circle is inscribed in a square with a side length of 144. If a point in the square is chosen at random, what is the probabili
____ [38]

Given :

A circle is inscribed in a square with a side length of 144.

So, radius of circle, r = 144/2 = 72 units.

To Find :

The probability that the point is inside the circle.

Solution :

Area of circle,

A_c = \pi r^2\\\\A_c = 3.14 \times 72^2\ units^2\\\\A_c = 16277.76 \ units^2

Area of square,

A_s = (2r)^2\\\\A_s = ( 2 \times 72)^2\ units^2\\\\A_s = 20736\ units^2

Now, probability is given by :

P = \dfrac{A_c}{A_s}\\\\P = \dfrac{16277.76}{20736}\\\\P = 0.785

Therefore, the probability that the point is inside the circle is 0.785 .

Simplify the following expression.
Sloan [31]

Answer: 3x^{2}+12x


Step-by-step explanation:

1. To solve simplify the expression given in the problem, you must apply a property of exponents called Quotient of powers, which states that when you divide two powers that have the same base, you must subtract the exponents.

2. Keeping this property on mind, you can rewrite the expression as following and simplify:

\frac{-12x^{3}}{-4x}-\frac{48x^{2}}{-4x}=3x^{2}+12x
