Answer:
12+x=12+4=16
3x+y=3*4+7=12+7=19
4y-10=4*7-10=28-10=18
1/2xy=1/2*4*7=28/2=14

Answer:
y=2x+1
Step-by-step explanation:
Parallel = gradients are the same
Example: y=2/4x+5
Perpendicular = gradients are the inverse of each other
Example: y= -4/2x+1
Any equation would be correct unless the gradient is 2/4 or -4/2
Answer: 1.5
Step-by-step explanation: In order to find the scale factor, all you would need to do is pick 2 sides that are the similar (in this case, 6 and 9), and divide them.
9/6 = 1.5
And that will give you the scale factor!
