Are the ratios 2:3 and 12:18 equivalent?

lesya692 [45]

Answer: Yes

Step-by-step explanation:

Yes, they are, because if you multiply 2*6=12 and 3*6=18, so here we multiplied both 2 and 3 by the same number (6) and we got the same result 12:18. This method also works with fractions.

Find three solutions for this linear function and choose the correct graph by clicking on it. F -1(x) if F(x) = x + 3

algol13

Answer:

[1,2], [2,1], [3,0]

Step-by-step explanation:

To find F-1(x) if F(x)=x+3 we just need to put -x instead of x.

From our graph(attached) we multiply any three solutions by a -1:

$F-1(x)\\\\#For \ x=1\\F-1(1)=-1+3=2\\\\#For \ x=2\\F-1(2)=-2+3=1\\\\#For \ x=3\\F-1(3)=-3+3=0$

Hence, the 3 solutions are [1,2],[2,1],[3,0]
