Answer:
y=2x + 2
0= 2x +2
-2x = 2
x= -1
Step-by-step explanation:
2y = 4x +4
2y -4x =4
y-2x =2
-2x +y =2
2x-y=-2
Answer:
B. 7.9 in^2
Step-by-step explanation:
Part I.
Finding the fraction of the circle that is the sector
To start, let’s find the fraction of the circle that the sector covers. Since the measure of the central angle is 36, we get 36/360 or 1/10 of the circle.
Part II.
Finding the area of the Circle
The area of a circle is pi*r^2. Since r=5, then the area is 25pi.
Part III.
Finding the area of the sector.
Since the sector is 1/10 of the circle, its area is 1/10 of the circle’s area. So the area of the sector is 25/10*pi or (5/2)pi. This is approximately 7.9 in^2.
Surface area of a rectangular pyramid = A + 1/2 p s
Where:
A = area of the base
p = perimeter of the base
s= salnt height = 5 in
A = Area of a rectangle = length x width = 8 x 4 = 32 in2
Perimeter of the base = 2 lenght + 2 width = 2(8)+2(4) = 24 in2
SA = 32 + 1/2 * 24 * 5 = 92 in2

Answer:
The exact distance is 
miles.
The distance is approximately 10.4 miles.
Step-by-step explanation:
It is given that a rectangular city is 3 miles long and 10 miles wide. So,
Length = 3 miles
Width = 10 miles
We need to find the distance between opposite corners of the city. It means, we need to find the length of the diagonal of the rectangle.
Using Pythagoras theorem, the length of diagonal is
where, l is length and w is width.
Substitute l=3 and w=10.
The exact distance is miles.
Now,
The distance is approximately 10.4 miles.
