No thanks I’m good but someone else might sorry
1a because it is going through the origin. if the line is going straight through the origin then it is automatically proportional. hope this helps in the future
Answer:
Step-by-step explanation:
3.3x - 6.6 = 2.7x
by transposing method,
3.3x - 2.7x = 6.6
0.6x = 6.6
so the answer is 0.6x = 6.6
hope this helps

Answer:
Step-by-step explanation:
A 2nd order polynomial such as this one will have 2 roots; a 3rd order polynomial 3 roots, and so on.
The quadratic formula is one of the faster ways (in this situation, at least) in which to find the roots. From 2x^2 + 4x + 7 we get a = 2, b = 4 and c = 7.
Then the discriminant is b^2 - 4ac, or, here, 4^2 - 4(2)(7), or -40. Because the discriminant is negative, we know that the roots will be complex and unequal.
Using the quadratic formula:
-4 ±√[-40] -4 ± 2i√10
x = ------------------ = ------------------
4 4
-2 ± i√10
Thus, the roots are x = ------------------
