<h3>Answer:</h3>

[5] <u>By central angle property</u>,

  • x = 6x - 290
  • x - 6x = - 290
  • - 5x = - 290
  • x = 290/5
  • x = 58.

[6] <u>By same arc property</u>,

  • 8x + 4 = 9x - 11
  • 8x - 9x = - 11 - 4
  • - x = - 15
  • x = 15.

[7] <u>By central angle property</u>,

  • 7x + 4 = 2x + 49
  • 7x - 2x = 49 - 4
  • 5x = 45
  • x = 45/5 = 9.

[8] <u>As they are radius i.e, equal</u>,

  • x + 9 = 2x + 6
  • x - 2x = 6 - 9
  • - x = - 3
  • x = 3.

[9] <u>By central angle property</u>,

  • 9x = 12x - 21
  • 9x - 12x = - 21
  • - 3x = - 21
  • x = - 21/- 3
  • x = 7.

[10] <u>They are radius so equal</u>,

  • 8x + 2 = 10x - 20
  • 8x - 10x = - 20 - 2
  • - 2x = - 22
  • x = -22/-2
  • x = 11.

How do the graphs of the functions f(x) = (Three-halves)x and g(x) = (Two-thirds)x compare?
miss Akunina [59]

Answer:

The answer to this question can be defined as follows:

Step-by-step explanation:

Given:

\bold{f(x)= (\frac{3}{2})^x}\\\\\bold{g(x)= (\frac{2}{3})^x}\\

Following are the graph attachment to this question:

The second function, that is g(x)= (\frac{2}{3})^x is not even a function.

Remember that g(x) function is the inverted f(x) function. And when you see this pattern, a reflection on the Y-axis expects you.

Reflection in the axis.

In x-axis:

Increase the function performance by -1 to represent an exponential curve around the x-axis.

In y-axis:

Increase the input of the function by -1 to represent the exponential function around the y-axis.

Zane bought a pair of jeans that originally cost $56. He used a coupon for 25% off and paid 8% in sales tax. How much did he pay
sattari [20]

Answer:

$38.64

Step-by-step explanation:

so the equation needed to solve is $56*0.25 and that number is 14. Since it is a coupon you subtract 14 from 56 and end up with 42. Now multiply 0.08*42 and you got your sales tax, $3.36. now subtract that from 42 and you have your answer! Don't forget the dollar sign!

hope this helped! : )

The equation y = 0.035x shows the relationship between the grams and ounces.
scoundrel [369]
The equation y = 0.035x where x is in grams, and y is ounces, then 22 grams would be 0.035 x 22 = 0.77 ounces
