Answer:

a = - 1, b = - 3, c = - 5, d = - 6

Step-by-step explanation:

Substitute the appropriate values of x into the equation and evaluate

x = - 3 : y = - (- 3) - 4 = 3 - 4 = - 1 → a

x = - 1 : y = - (- 1) - 4 = 1 - 4 = - 3 → b

x = 1 : y = - 1 - 4 = - 5 → c

x = 2 : y = - 2 - 4 = - 6 → d

Step-by-step explanation:

The result after simplifying the expression is [tex]\frac{12}{x^2-2x-8}[/tex]

Given the difference of function expressed as:

[tex]\frac{x^2-3x+2}{x^2-5x+4} -\frac{x^2+10x+24}{x^2+8x+12} \\[/tex]

Factorize the quadratic equations:

[tex]=\frac{x^2-2x-x+2}{x^2-4x-x+4} -\frac{x^2+4x+6x+24}{x^2+6x+2x+12} \\=\frac{x(x-2)-1(x-2)}{x(x-4)-1(x-4)} -\frac{x(x+4)+6(x+4)}{x(x+6)+2(x+6)}\\=\frac{(x-1)(x-2)}{(x-1(x-4)} -\frac{(x+6)(x+4)}{(x+2)(x+6)}[/tex]

Cancel out the common terms:

[tex]\frac{(x-2)}{(x-4)} -\frac{(x+4)}{(x+2)}[/tex]

Find the LCM of the resulting expression

[tex]=\frac{(x-2)}{(x-4)} -\frac{(x+4)}{(x+2)}\\=\frac{(x+2)(x-2)-[(x-4)(x+4)]}{(x-4)(x+2)} \\=\frac{x^2-4-(x^2-16)}{(x-4)(x+2)} \\=\frac{x^2-4-x^2+16}{(x^2+2x-4x-8)}\\=\frac{12}{x^2-2x-8}[/tex]

Hence the result after simplifying the expression is [tex]\frac{12}{x^2-2x-8}[/tex]

Answer:

  x = 12

  perimeter = 124

Step-by-step explanation:

The midline RS is half the length of MN, so we have ...

  2×RS = MN

  2(x +3) = 5x -30

  2x +6 = 5x -30

  36 = 3x . . . . . . . . . add 30-2x

  12 = x . . . . . . . . . . divide by 3

__

The length RS is then ...

  RS = x +3 = 15

and the perimeter of QRS is ...

  P(QRS) = QR +RS +SQ = 25 +15 +22 = 62

The perimeter of QRS is half the perimeter of MNP, so ...

  P(MNP) = 2×P(QRS) = 2×62 = 124

The perimeter of ΔMNP = 124.

Answer:

{-1,7}

Step-by-step explanation:

1/2 | 5x-15| = 10

Multiply each side by 2

1/2 *2 | 5x-15| = 10*2

| 5x-15| = 20

Absolute value equations have two solutions, one positive and one negative

5x-15 = 20     5x-15 = -20

Add 15 to all sides

5x-15+15 = 20+15          5x-15 +15 = -20+15

5x= 35                                   5x=-5

Divide by 5

5x/5 = 35/5                              5x/5 = -5/5

Parallelogram EFGH  has vertices at E(-1, 4), F(-1, 6), G(3, 3) and H(3, 5)

Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, reflection, translation and dilation.

If point A(x , y) rotated about the origin by angle 90°, then its image is A'(-y , x).

The parallelogram ABCD has vertices at A(4,1), B(6, 1) C(3, -3) and D(5, -3).

Hence the transformation EFGH = Ro 90° ( ▱ ABCD), gives:

E(-1, 4), F(-1, 6), G(3, 3) and H(3, 5)

Use foil method

(10 - 3i) (2 -5i) = 10*2 + 10*(-5i)  +  (-3i)*2 + (-3i)*(-5i)

   = 20 - 50i -6i + 15i²

Answer:

y=-9x-10

Step-by-step explanation:

First, start by putting the first equation into slope intercept form:

y=-9x+5

We know that in the standard slope intercept formula (y=mx+b), m is the slope and b is the y intercept. Thus, line with the same slope as the one above would have a slope of -9.

To have the same y intercept as y=-8x-10, the y intercept would have to be -10.

Therefore, the formula would be y=-9x-10

Answer:

y = - 6/5x + 8/9

Step-by-step explanation:

For this case we have that by definition, the equation of the line of the slope-intersection form is given by:

Where:

m: It is the slope of the line

b: It is the cut point with the y axis

We have the following equations:

Equation 1:

By definition, if two lines are perpendicular then the product of their slopes is -1:

Equation 2:

Answer:

the answer to the first question is B.

Step-by-step explanation:

Answer:

  A: 2 1/2 ft^2/h

  B: 3 1/3 ft^2/h

  B has the greater rate

Step-by-step explanation:

The rate in square feet per hour is found by dividing square feet by hours.

Machine A:

  (5/8 ft^2) ÷ (1/4 h) = (5/8)×(4/1) ft^2/h = 5/2 ft^2/h = 2 1/2 ft²/h

Machine B:

  (2/3 ft^2) ÷ (1/5 h) = (2/3)×(5/1) ft^2/h = 10/3 ft²/h = 3 1/3 ft²/h

Machine B has the greater rate.

Answer:

0

Step-by-step explanation:

→ State the slope formula

( y₂ - y₁ ) ÷ ( x₂ - x₁ )

→ State each value

x₁ = 3, y₁ = 18, x₂ = 0 and y₂ = 18

→ Substitute in each value into the formula

( 18 - 18 ) ÷ ( 0 - 3 )

→ Simplify
