3+2 = 5
30 / 5 = 6
so
3 x 6 = 18
2 x 6 = 12
answer
ratio 3: 2 =18:12
IF IT IS THE EQUATION OF A LINE YOU ARE LOOKING FOR:
y=mx+c
7-1÷5-3=6÷2=3
y=3x+c (here we substitute in one of the points to find out what C is)
1=(3×3)+c
1=9+c
-8=c
so the equation is: y=3x-8
Remark
The key to this is the point (1,-3) That point must be found first. C is incorrect because you are using 3 not - 3 which does not change (as C has changed it) through out the problem.
A is using (-1,-3) which makes it wrong. Also the equation is y = -abs(x-1) - 3 which is also a mistake. The given graph points upwards not downwards.
D has it's min point at (-1,-3) which is not correct.
You are left with b which opens upwards (correct) has it's min at (1,-3) [also correct] so the answer is
Answer: B
There are many solutions. infinite solutions at that. when you solve it it equals itself 2.5w+21= 2.5w+21 so that means all numbers would work as a solution.
