Answer:
The relationship between the graphs is the intersection point at (0.667,1.333)
Step-by-step explanation:
we have
y=2x ----> equation A
The slope of the line A is equal to m=2
The line passes through the origin
y=2-x ----> equation B
The slope of the line B is m=-1
The x-intercept is the point (2,0)
The y-intercept is the point (0,2)
Line A and Line B are not parallel (the slopes are not equal)
Line A and Line B are not perpendicular (the product of their slopes is not equal to -1)
so
The relationship between Line A and Line B is the intersection point both graphs
using a graphing tool
The intersection point is (0.667,1.333)
see the attached figure
The intersection point is a common point , therefore belongs to both lines
Answer:
The value of x is 13°
Step-by-step explanation:
<u>Given:</u> m || n
For a straight line = 180°
Now, by exterior angle
(7x - 1)° + (8x - 14)° = 180°
7x - 1° + 8x - 14° = 180°
15x - 15° = 180°
Now, add 15° both side we get,
15x - 15° + 15° = 180° + 15°
15x = 195°
Now, divide both side by 15
15x/15 = 195°/15
x = 13°
Thus, The value of x is 13°

Equation is :
( x + 2 )² + ( y - 1 )² = r²
( - 4 + 2 )² + ( 1 - 1 )² = r²
4 = r², than we will plug in to a formula:
( x + 2 )² + ( y - 1 )² = 4
x² + 4 x + 4 + y² - 2 y +1 = 4
x² + y² + 4 x - 2 y + 1 = 0
Answer: B )
So the image consists of 1 rectangle and half a circle.
Rectangle - 12*19 = 228
Half a circle -

In the end there are 2 rectangles (2*228 = 456) and 1 full circle (18*2 = 36), which makes the shaded area 456 ft and 36
