Answer:

Solution: (1,-2)

Step-by-step explanation:

System of Equations

Given the equations:

[tex]-7x-8y=9\qquad\qquad [1][/tex]

[tex]-4x+9y=-22\qquad\qquad [2][/tex]

We'll solve it by elimination. It means eliminating one of the variables by equating their coefficients. We select the variable y. To eliminate it, multiply the equation [1] by 9 and the equation[2] by 8:

-63x-72y=81

-32x+72y=-176

Adding up both equations:

-95x=-95

Solving:

x=-95/(-95)=1

x=1

Now to eliminate x and find y, multiply [1] by 4 and [2] by -7:

-28x-32y=36

28x-63y=154

Adding up both equations:

-95y=190

Solving:

y=190 / (-95) = -2

y=-2

Solution: (1,-2)

Answer:

k = -8

Step-by-step explanation:

-2k+13=-8k-35

Add 8k to each side

-2k+8k+13=-8k+8k-35

6k +13 = -35

Subtract 13 from each side

6k+13-13 = -35-13

6k = -48

Divide by 6

6k/6 = -48/6

k = -8

Answer:

The Answer is 1 over 7 times 7 times 7 times 7 times 7 times 7

Step-by-step explanation:

All you have to do is multiply the exponents.

[tex]7^{3*(-2)} =7^{-6}[/tex]

and the rule says :

[tex]x^{-a} = \frac{1}{x^{a} }[/tex]

So that means :

[tex]7^{-6} =\frac{1}{7^{6} } =\frac{1}{7*7*7*7*7*7}[/tex]

1 over 7 times 7 times 7 times 7 times 7 times 7  is equivalent to (73)−2.

In mathematics, multiplication is a method of finding the product of two or more numbers. It is one of the basic arithmetic operations, that we use in everyday life.

Here we have,

(7^3)(−2)

=7^(-6)

=1/7^6

=1/7*7*7*7*7*7

Hence, 1 over 7 times 7 times 7 times 7 times 7 times 7  is equivalent to (73)−2.

The length of the longer diagonal of this parallelogram is 10.8.

A parallelogram is a rectangle with two pairs of parallel sides. The lengths of the opposite sides of the parallelogram are equal, and the angles of the opposite sides are the same. Also, the internal angles on the same side of the transversal are complementary. The sum of all internal angles is 360 degrees.

A parallelogram is a simple (non-self-intersecting) quadrilateral with two pairs of parallel sides. The lengths of the opposite or opposite sides of the parallelogram are equal, and the angles of the opposite sides of the parallelogram are equal.

The expression that represents the perimeter in centimetre of the triangle is  4r - 16s + 4t

Perimeter of a triangle is the sum of the whole sides. The triangle has three sides. Therefore, the perimeter is the sum of the three sides.

The side length are as follows;

Therefore,

perimeter = r - 10s + 3r + 2t + 2t - 6s

combine like terms

perimeter = r + 3r - 10s - 6s + 2t + 2t

perimeter = 4r - 16s + 4t

each point of the given figure has to be changed from (x, y) to (y, -x)

Answer:

Step-by-step explanation:

c.  y = (x^2 + 3)(x + 4)

y = x^3 + 4x^2 + 3x + 12

d. y = (x^2 + x) / √x

y =   (x^2 + x) /  x^1/2

y = x^2/ x^1/2  +  x / x^1/2

y = x^(2 - 1/2) + x(1 - 1/2)

y = x^3/2 + x^1/2

or x =  √(x^3) + √x

e.   y = 5 /x^2

y = 5x^(-2)

Answer:

x ≈ 11.6 m

Step-by-step explanation:

using Pythagoras' identity in the right triangle

the square on the hypotenuse is equal to the sum of the squares on the other 2 sides , that is

x² + 10.7² = 15.8²

x² + 114.49 = 249.64 ( subtract 114.49 from both sides )

x² = 135.15 ( take square root of both sides )

x = [tex]\sqrt{135.15}[/tex] ≈ 11.6 m ( to the nearest tenth )
