Since these are supplementary angles  (two angles which sum to 180°) we can say:

4x+x=180  combine like terms on left side

5x=180  divide both sides by 5

x=36°

A balloon artist creates balloon hats for children at a store’s grand opening. The graph shows the number of balloons the artist
Dvinal [7]

Answer:

The phrase that best describes the the line representing the relationship between the number of balloons remaining and the number of hats created is:

  • Negative slope.
  • Constant slope.
  • Decreasing function.

Step-by-step explanation:

We are given a graph that represents the relationship between the Number of Balloons Hats and the number of balloons remaining.

Clearly from the graph we could that it is  a linear function.

Also, the function is a decreasing function since with the increase of one variable that is the number of Balloon hats produced the other variable i.e. Balloons remaining is decreasing.

Also, we can calculate the slope of the line.

as the line is passing through (0,500) and (100,0)

Hence, the slope of line is:

Slope=\dfrac{0-500}{100-0}\\\\Slope=\dfrac{-500}{100}\\\\Slope=-5

Hence, the graph has a negative slope.

Also, we know that a slope of a line is always constant.

So, the correct statements are:

Negative slope.

Constant slope.

Decreasing function.

Naddika [18.5K]
The correct answer is option D

The solution is shown below:

x^{2} +16 \\  \\ 
= x^{2} +(4)^{2} \\  \\ 
= x^{2} -(-1)(4)^{2}   \\  \\ 
= x^{2} -i^{2} (4)^{2} \\  \\ 
= x^{2} -(4i)^{2} \\  \\ 
=(x+4i)(x-4i)

What is the x-intercept of the line containing the points (–6, 10) and (12, –2)?
const2013 [10]
Slope = (-2 - 10)/(12 + 6) = -12/18 = -2/3

y = mx + b
10 = -2/3(-6) + b
10 = 4 + b
b =6

equation
y = -2/3x + 6

<span>x-intercept when y = 0
</span>-2/3x + 6 = 0
-2/3x = -6
      x = 6 (3/2)
      x = 9

answer is <span>d.9</span>
