Jessie graphed one of the lines in a system of equations: Y=3x-2 If the system has an infinite number of solutions, which statem
ents are true? Check all that apply.
1. Any point in the coordinate plane is a solution because it has an infinite number of solutions.
2. Point (1, 1) is a solution because it is one of the points on the line already graphed.
3. It is impossible to tell if (–1,–5) is a solution without seeing the other line graphed.
4. Point (20, 58) is a solution because it results in a true statement when the point values are substituted into the equation of the line.
5. When the other line in the system is graphed, it will share all points with the line already graphed.

Answer:
G. 7600
Step-by-step explanation:
Step 1: Deconstruct the shape
2 rectangles with dimension of 50 cm x 20 cm
2 rectangles with dimension of 40 cm x 20 cm
2 rectangles with dimension of 40 cm x 50 cm
Step 2: Find surface area of the shapes
2(50 x 20) = 2000
2(40 x 20) = 1600
2(40 x 50) = 4000
Step 3: Add the surface areas together
2000 + 1600 + 4000 = 7600
Therefore the surface area is 7600 and the answer is G.
Answer:
2
Step-by-step explanation:
let the other leg be x
Using Pythagoras' identity
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
x² + 1² = 3²
x² + 1 = 9 ( subtract 1 from both sides )
x² = 8 ( take the square root of both sides )
x =
=
= ×
= 2
← exact value
