X=83. This is because all of the answers combined (excluding 2x) is 664. there are a total of 6 exterior angles. now you take the 6 total angles + 2x. which is 8x. here is your equation. 8x=664. divide each side by 8. x=83.

The future worth of a certain item or money deposited at a certain percentage is obtained by the equation,

   F = P x (1 + i)^n

F is the future worth, P is present worth, i is the percentage, and n is the number of years.

   n = 2013 - 1938
   n = 75

Substituting the known values,

    300,000 = 100 x (1 + i)^75

The value of i from the equation is 0.1126.

The answer to this item is 11.26%.

Find the composite area of the polygon
KIM [24]

Answer:

Obtaining the area or perimeter is the easiest and basic skills in geometry, however, when combining several plane figures, composite shapes are formed, which can include: squares, circles, triangles, rectangles, trapezoids, etc.

To obtain the area or perimeter of this type of figures should analyze the figure and follow these steps:

STEP I

♦ Must identify which figures form the total.

STEP II

 

♦ Analyze if there are parts of the figures that you will not need, for example the sides that join two or more figures.

STEP III

 

♦ Obtain separately the areas and perimeters of each figure

STEP IV

♦Add the obtained in each figure.

Hope it helps you!

2x+7y=11 is (-5,3) on the graph
Lelu [443]

Step-by-step explanation:

The given equation is :

2x+7y=11

We need to tell the point (-5,3) lies on the graph of the above equation of not.

Put x = -5 and y = 3 in the LHS of the above equation.

LHS = 2x+7y

= 2(-5)+7(3)

= -10 +21

= 11

It means, when we put  x = -5 and y = 3 in the above equation, we get 11. Hence, (-5,3) lies on the graph of the equation.

1) Find an equation of the line that passes through thr pair of points (-5,-9) and (2,-7).
Yuki888 [10]
1: Assuming this line is linear, the first thing to do is find the slope. 
The slope formula is m=\frac{ y_{2} - y_{1} }{ x_{2} - x_{1} }, so in this case, it is m=\frac{ (-7) - (-9) }{ 2 - (-5) }, which comes to \frac{2}{7}. Then, use your slope and one of the points given to write the point-slope formula of the linear equation, and then written in standard form:
y=\frac{2}{7}x-\frac{53}{7}.

2. Use the same process as in question 1 to find:
y=-7x+11
