Answer:
1230
Step-by-step explanation:
80 x 4 = 320
320 + 910 = 1230
The answer to that would be 0 because the line goes through the orgin witch the points are 0
I believe that the answer is 20. I am not entirely sure though.
Answer:12
Step-by-step explanation:
Let the numbers be a and b
a-3b=5 ........equation (1)
There product is :
ab=68 ..........equation (2)
From equation (1)
a-3b=5
Make a the subject of the formula
a=5+3b. ........equation (3)
Substitute equation (3) into equation (2)
(5+3b)b=68
3(b^2)+3b-68=0
The product is -204b^2(17 and -12)
(b+17)(b-12)=0
b=-17 or b=12
So the number is 12
