We will use a method of substitution.
y = 5/2 x + 2
2 y = 5 x + 4 ⇒ 2 ( 5/2 x + 2 )= 5 x + 4
5 x + 4 = 5 x + 4
0 x = 0 ⇒ x, y ∈ R

Answer:
parallel
Step-by-step explanation: It was hard to guess since it didn't show no shape.
Answer:
4 times 5 = 20, and 20 is... well.. 20
Step-by-step explanation:
When a number has another number in parentheses by it, it means you multiply the numbers together. So 4(5) is the same as 4 times 5, which equals 20

Answer:
Step-by-step explanation:
Triangle ABC is a right angle triangle that is made up of 2 right angle triangle.
To determine y, we would apply Pythagoras theorem which is expressed as
Hypotenuse² = opposite side² + adjacent side²
15² = y² + 12²
225 = y² + 144
y² = 225 - 144 = 81
y = √81 = 9
To determine z,
20² = z² + 12²
400 = z² + 144
z² = 400 - 144 = 256
z = √256 = 16
