The first one, WX is perpendicular to ZY and WX is parallel to AB
Answer:
x = -6 and -1
Step-by-step explanation:
x^2 + 6x + 7
Factorise- find two numbers that multiply to be 6 and add to be 7: 6 and 1
(x+6)(x+1)
Set each expression equal to 0 and solve
x + 6 = 0 -> x = -6
x + 1 = 0 -> x = -1
You can use a scale factor of 2 to dilate the original and get the final. I got this answer by doing:
y x 6 = 6y (y represents the original rectangle, 6y represents the second rectangle)
then, 6y x 1/3 = 2y (2y represents the final rectangle)
If you compare the original rectangle (y) to the final (2y), you see that the final is 2 times the original, therefore the scale factor is 2
Answer:
Step-by-step explanation:
Example of a linear function: y = -5x + 2. Note that both x and y are to the first power: y^1 and x^1.
Example of a nonlinear function: y = 2x^2 - x - 13. Here x is to the second power (which automatically makes this a nonlinear function).
4 only has three factors 1,2,4. 4 times 1 and 2 times . No other possible combinations making Adam wrong.
