Can someone tell me the equation of this graph 1. f(x)=1/4x + 4
2. y=1/2x + 4
3. y=2x + 4
4. f(x)= - 2/3x + 4

50 points! antonio made a scale model of a building. the model's scale is 1 inch to 235 feet and its height is 3.5 inches. what is the exact height of the actual building? enter your answer in the box.

Which of these equations, when solved, gives a different value of x than the other three? a9.1 = -0.2x + 10 b10 = 9.1 + 0.2x c10 – 0.2x = 9.1 d9.1 – 10 = 0.2x

If square root x = -7, then x= -49 true or false
