Solve the system of equations below by graphing both equations with a pencil and paper. What is the solution?

Answers

Answer 1

Answer:

Answer: B. (2,1)

Step-by-step explanation:

The given system of equation :

$y=2x-3...........................(1)\n\ny=-2x+5.............................(2)$

Adding equation (1) and (2), we get

$2y=-3+5\n\n\Rightarrow\ 2y=2\n\n\Rightarrow\ y=1$

Substitute the value of y in the first equation , we get

$1=2x-3\n\n\Rightarrow\ 2x=1+3\n\n\Rightarrow\ 2x=4\n\n\Rightarrow\ x=2$

Therefore, the solution to the given system of equations = (2,1)

The following 3-D object is composed of identical cubes. The volume of the 3-D object is 56cm cubed. The surface area of the 3-D object is
a) 30cm squared
b) 60cm squared
c) 120cm squared
d) 144cm squared

Answers

There are 7 equal cubes by inspection that make up the shape.

Each cube has a volume of: (56 cm^3)/7 = 8 cm^3

To find side dimension of cube (knowing a cube is the 3D extrusion of a square meaning all sides are equal:

s = (side dimension) = (8 cm^3)^(1/3) = 2 cm

Also by inspection, there are 5 exposed faces on 6 of the 7 cubes. To find the total surface area, multiply number of exposed faces per cube by the surface area of a single face:

S.A. = 5(6)(2*2) = 120 cm^2

The correct answer is C). 120cm squared
