Which ordered pair is the solution to the system of equations below when
using the matrix tool?
9x - 3y = 54
9x +1 ly = 12

Answers

Answer 1

Answer:

(7, -3)

Step-by-step explanation:

9x - 3y = 54

9x +1 ly = 12

Subtract both expresion

-3y - 11y = 54 - 12

-14y = 42

y = 42/-14

y = -3

Substitute y = -3 into 1;

From 1, 9x - 3y = 54

9x - 3(-3) = 54

9x - 9 = 54

9x = 54 + 9

9x = 63

x = 63/9

x = 7

Hence the solution to the system of equation is (7, -3)

Given:

The function is:

[tex]f(x)=-4x^9[/tex]

To find:

The end behaviors of the given function.

Solution:

We have,

[tex]f(x)=-4x^9[/tex]

The leading coefficient is -4 which is a negative value and the degree of the leading coefficient is 9 which is an odd number. So,

[tex]f(x)\to \infty[/tex] as [tex]x\to -\infty[/tex].

[tex]f(x)\to -\infty[/tex] as [tex]x\to \infty[/tex].

Hence, as [tex]x\to -\infty[/tex], [tex]f(x)\to \infty[/tex] and as [tex]x\to \infty[/tex], [tex]f(x)\to -\infty[/tex].

The top numbers have a scale of 1.5 so the bottom numbers also have a scale of 1.5

Multiply the known bottom number by the scale:

[ ? ]%

Answers

Answer:

78.5%

Step-by-step explanation:

the percent of time the point will land in the square can be determined by dividing the area of the square by the area of the circle

A(circle) = 3.14(1)²

A(circle) = 3.14

A(square) = side squared

if radius of square is 1 inch then each side is 2 inches

A(square) = 2²

A(square) = 4 inches

3.14/4 = 78.5%

The flounder is a type of marine flatfish. Flounders lurk on the ocean floor to ambush smaller fish and other prey. When flounders are born, their eyes are located on each side of the head, but as the flounder grows, one of its eyes migrates to the other side so that both eyes are on the same side of its body. As the fish lies on the seafloor, both eyes look upward, alert for prey or predators. To protect itself, the flounder also uses camouflage, changing its color to match its surroundings. For example, the flounder appears a dull, spotted color when lying on the seafloor but turns almost transparent when swimming near the surface. What is the purpose of the underlined sentence?
