Answer:
y = 
Step-by-step explanation:
Given
x = 2y - 3 ( add 3 to both sides )
x + 3 = 2y ( divide both sides by 2 )
= y
Answer:
True
Step-by-step explanation:
If the triangle was a right angled triangle then we can prove it using the Pythagoras theorem: c² = a² + b²
c is the largest side and a and b are the two smaller sides of the triangle.
So if this is true then √72² + 154² should be 170:
170² = 72² + 154²
28900 = 5184 + 23716
28900 = 28900
So we have proved using Pythagoras theorem that the triangle is a right angled triangle.
Answer:
never touches the y-axis
touches the y-axis at -4
Step-by-step explanation:
Because -4 means that the graph touches the y-axis at negative 4, not having it means that it never touches the y-axis
