Answer:

x=8

Step-by-step explanation:

30-3x=3x-24+6

-3x-3x= -24+6-30

-6x= -18-30

-6x= -48

x= -48/-6

x=8

10. from the question; the circle theorem obeyed is "angled formed by semi-circle"

The angle formed in a semicircle is 90 degrees, hence

m\angle XYZ=90^{\circ}

This gives

m\angle YXZ\text{ + m}\angle YZX\text{ = 90}

But

\begin{gathered} m\angle YXZ\text{ = 2x + 8} \\ m\angle YZX\text{ = 5X - 2} \end{gathered}

Substituting values we get

\begin{gathered} 2x\text{ + 8 + 5x - 2 = 90} \\ 2x\text{ + 5x + 8 - 2 = 90} \\ 7x\text{ + 6 = 90} \\ 7x\text{ = 90 -6} \\ 7x\text{ = 84} \\ \text{divide both sides by 7} \\ x\text{ = }\frac{84}{7} \\ x\text{ = 12} \end{gathered}

hence, x =12

What is the difference between 3/7 and 1/14<br> A 1/2<br> B 4/14<br> C 5/14<br> D 9/14
Cerrena [4.2K]
C. 5/14
You find the LCD. In this case it would be 14 since both 7 and 14 can go into 14. You have to multiply the top by the same number as the bottom. 2*7=14
2*3=6. You now have 6/14. 6-1=5 
The denominator stays the same. 5/14

The red square is the image of the blue square after a SINGLE transformation. Use two or more complete sentences to describe eac
Leni [432]

The transformations which can lead to the red square image of the blue Square are; Translation, Reflection, Rotation.

<h3>What transformations lead to the image?</h3>

  • Translation is when we slide a figure in any direction. The translation of the shape can be by moving the blue leftward or rightward and the then downward.
  • Reflection is when we flip a figure over a line. The reflection involves reflect the blue Square over the line; y = x.
  • Rotation is when we rotate a figure a certain degree around a point. The rotation is by rotating the blue Square over 180⁰.

Use the Rational Zeros Theorem to write a list of all possible rational zeros of the function.f(x) = 3x3 + 39x2 + 39x + 27
kramer

First, we can factor this to make it easier to solve:

3(x^3 + 13x^2 + 13x + 9)

Now, we can use the rational root theorem like so:

List factors of 9:

1, 3, 9.

List factors of 1:

1

Because of this, we know our possible rational roots are:

+/-1, +/-3, +/-9

If none of these zeros fit using the remainder theorem, then we know our roots will be irrational.
