Answer:

Step-by-step explanation:

-x-3=y, therefore x = -y-3

-3x - 8y = 4

Find the value of y

Substitute the x in -3x - 8y = 4 with -y-3

We get

-3·(-y-3) - 8y = 4

3y + 9 - 8y = 4

-5y = 4-9

-5y = -5

STEP BY STEP

Substitution:

-x-3=y

-3x-8y=4

Solve for X                Substitute for Y

-3x-8(-x-3)=4                     -(-4)-3=y

-3x+8x+24=4                        4-3=y

5x+24=4                                y=1

    -24

5x=-20

5/5 = -20/5

x=-4

Solution: (-4,1)

Answer:

Prism A

Step-by-step explanation:

formula for prism triangular prisms: V=1/2(bhl) so V=1/2(4 x 7 x 9) V=126 m

formula for rectangular prisms: V=b x h x l so V= 8 x 8 x 2 V=128

126 is less than (<) 128 so Prism A

Answer:

(x + 1)² + (y + 1)² = (√6)²

Step-by-step explanation:

Group the x- and y- terms together:

9x^2 + 18x + 9y^2 + 9y = 36

Factor out the coefficient 9:

x^2 + 2x + y^2 + y = 4

Complete the square of x^2 + 2x and then do the same for y^2 + 2y:

x^2 + 2x + 1 - 1 + y^2 + 2y + 1 - 1 = 4

Rewrite x^2 + 2x + 1 as the square of the binomial x + 1:

(x + 1)^2 + (y + 1)^2 - 2 = 4

Collect the constant terms on the right side:

(x + 1)^2 + (y + 1)^2 = 6

Rewrite 6 as (√6)^2:

(x + 1)² + (y + 1)² = (√6)² is the equation in standard form (x - h)² + (y - k)² = r²

Completing the square is done as follows:  x^2 + 2x

Start with x^2 + 2x

1.  Take half of the coefficient of x, which results in 2/2, or 1

2.  Square this result and add it to, and subtract it from x^2 + 2x

     x^2 + 2x + 1 - 1

3.  Rewrite the first three terms as the square of a binomial:  

     x^2 + 2x + 1 - 1 = (x + 1)² - 1.

Do the same for y² + 2y.

Simplifying Rational Expressions

The quotient of two polynomial expressions is called a rational expression. We can apply the properties of fractions to rational expressions, such as simplifying the expressions by canceling common factors from the numerator and the denominator. To do this, we first need to factor both the numerator and denominator. Let’s start with the rational expression shown.

Step-by-step explanation:

Use the identity :   a² - b² = (a + b )(a - b)

Answer:

x=85, y=45

Step-by-step explanation:

Answer:

x = 85 degrees

y = 45 degrees

Step-by-step explanation:

x = 180 - 95 (Angles on a straight line add up to 180 degrees.)

x = 85 degrees

y = 180 - 50 - 85 (Interior angles of a triangle add up to 180 degrees.)

y = 45 degrees

Answer:

See explanation

Step-by-step explanation:

Let the number of adults = a and the number of children = c.

Since the number of people using the pool is 288, we know that a + c = 288

Based on the price information, we know that 1.75c + 2.5a = 528

Combining these two equations allows us to solve for the values of a and c, the process for which follows

a = 288 - c

1.75c + 2.5(288 - c) = 528

c = 256

a = 288 - c = 288 - 256 = 32

a = 32

c = 256

Answer:

45.44units^3

Step-by-step explanation:

Volume of the shaded part = Volume of the triangular based prism - Volume of square based prism

Volume of prism = Base area * Height

Volume of the triangular based prism = (5 * 4 * 5.7)/2

Volume of the triangular based prism = 57units^3

Volume of square based prism = 1.7* 1.7 * 4

Volume of square based prism = 11.56units^3

Taking the difference

Volume of the shaded solid = 57 - 11.56
