Answer 1

Answer:

7.5

Step-by-step explanation:

a - (2a-1)/a

--------------------

(1-a)/3a

Multiply the top and bottom by 3a

a - (2a-1)/a              3a

-------------------- * ---------------

(1-a)/3a                     3a

3a *a - (2a-1)*3a/a

------------------------

          (1-a)/3a *3a

Simplify

3a *a - (2a-1)*3

------------------------

          (1-a)

3a^2 - 6a+3

------------------------

          (1-a)

Factor

3( a^2 -2a+1)

-----------------------

-(a-1)

3(a-1)^2

---------------

-(a-1)

Cancel like terms

-3(a-1)

Letting a = -1.5

Where would it go I know how to do X axis but not Y

Answers

Answer: (-1,2) and (2,2) Make sure to see explanation!

Step-by-step explanation:

Well you need to remember the Y reflection rule!

To reflect over the Y axis you must do this:

Take the points in this case

(1,2) and (-2,2)

And you need to use the equation (x,y) --> (-x,y)

So the new points you NEED TO GRAPH ARE

(-1,2) and (2,2)

Hope this helped!

Answer: (-1,2) and (2,2)

Step-by-step explanation:

reflection over the y axis, take the point (x,y) and change the sign of the X-value (-x,y). When You reflect over the y-axis, the y remains the same.

point (1,2) would become (-1,2) reflected over the Y

and (-2,2) would become (2,2)

Let $f(x) = x^3 + 3x ^2 + 4x - 7$ and $g(x) = -7x^4 + 5x^3 +x^2 - 7$. What is the coefficient of $x^3$ in the sum $f(x) + g(x)$?

Answers

Answer:

6

Step-by-step explanation:

Adding the two polynomials gives

(x^3 + 3x^2 + 4x - 7) + (-7x^4 +5x^3 + x^2 - 7) =

-7x^4 + (x^3 + 5x^3) + (3x^2 + x^2) + 4x + (-7-7) =

- 7x^4 + 6x^3 + 4x^2 + 4x -14

The x^3 term is 6x^3, so the desired coefficient is 6.

What is cosine rule?

In trigonometry, the Cosine Rule says that the square of the length of any side of a given triangle is equal to the sum of the squares of the length of the other sides minus twice the product of the other two sides multiplied by the cosine of angle included between them.

therefore m² = k²+l²+2klCos M

m² = 4.4²+3.1²+ 2× 3.1×4.4cos 150

m² = 19.36+9.61+27.28(-0.8660)

m² = 28.97-23.62

m² = 5.35

m = √5.35

m = 2.31 cm( nearest tenth)

Therefore the measure of length m is 2.31 cm

Identify each pair of angles as corresponding, Alternate interior, alternate exterior, or consecutive interior and solve for X

Answers

Answer:

Step-by-step explanation:

19). Angles measuring 90° and (21x + 6)° are Alternate exterior angles.

     Therefore, 21x + 6 = 90

     2x = 90 - 6

     2x = 84

      x = 42

21). Angles measuring 60° and (8x - 4)° are Alternate interior angles,

      8x - 4 = 60

      8x = 60 + 4

      x = [tex]\frac{64}{8}[/tex]

      x = 8

23). Since, angles measuring (-1 + 14x)° and (12x + 17)° are Alternate exterior angles

    Therefore, (-1 + 14x) = (12x + 17)

     14x - 12x = 17 + 1

     2x = 18

      x = 9

25). Both the angles (x + 96)° and (x + 96)° are consecutive interior angles.

      Therefore, (x + 96)° + (x + 96)° = 180° [Property of consecutive interior angles]

      2x + 192 = 180

      2x = 180 - 192

      2x = -12

       x = -6

       Now measure of (x + 96)° = -6 + 96

                                                = 90°

26). Both the angles (20x + 5)° and (24x - 1)° are consecutive interior angles.

      Therefore, (20x + 5)° + (24x - 1)° = 180°

       44x + 4 = 180

       44x = 176

        x = 4
