Answer:
x = 1, y = 1
Step-by-step explanation:
3x - 4y = -1
5x + 2y = 7
If we multiply the whole second equation by 2, we get:
10x + 4y = 14
Adding this to the first equation:
10x + 4y + 3x - 4y = 14 - 1
13x = 13
x = 1
Applying this to the second equation:
5 (1) + 2y = 7
2y = 2
y = 1
Answer:
84,375 m^2
Step-by-step explanation:
We need to find the surface area of the pyramid. The pyramid can be divided into 4 triangles and one square (the bottom).
Area of a triangle is 1/2*b*h where b is the base of the triangle and h is the height.
Area of a square is length times width.
Total area = 
Hey there!
6(3.14)^6
= 6(3.14^6)
= 6(3.14 * 3.14 * 3.14 * 3.14 * 3.14 * 3.14)
= 6(9.8596 * 9.8596 * 9.8596)
= 6(97.21171216 * 9.8596)
= 6(5,750.811583)
≈ 5750.81158328
Therefore, the answer should be:
5,750.81158328
Good luck on your assignment & enjoy your day!

Answer:
vertex = (- 1, 1 )
Step-by-step explanation:
Given a parabola in standard form
y = ax² + bx + c ( a ≠ 0 )
Then the x- coordinate of the vertex is
x = - 
y = x² + 2x + 2 ← is in standard form
with a = 1 and b = 2 , then
x = -
= - 1
substitute x = - 1 into the equation for y- coordinate of vertex
y = (- 1)² + 2(- 1) + 2 = 1 - 2 + 2 = 1
vertex = (- 1, 1 )

Information provided
Weight of ant=
Weight of lion=
but units are not provided, assuming this unit is also grams
How many times lion's weight exceed an ant

=
Therefore, the value of x=7 if the unit for weight of lion is assumed to be same as unit for weight of an ant
