Yap,
It seems to me that there are two answers. Both y = .5x and y = 12x. Direct variation is what I'm thinking of so hopefully this helps.
BTW - with Direct Variation, the line will go through (0, 0).
Answer:(1,-1)
Step-by-step explanation:
Y= -2x+1
3x -2(-2x*1)=5
3x+(4x-2)=5
7x-2 =5
+2 = +2
7x=7
x= 1
Solution : (1,-1)
Answer:
4√5
Step-by-step explanation:
Facts:
MR Price takes his wife + two children
The price of adult's ticket is 2 times higher that child's
They paid $12.6 in total
Answer:
X is the price of child's ticket so equation will look:
2x (fathers' ticket) + 2x (mother's ticket) + x (first child) + x (second child) = $12.6 (total price)
6x = 12.6
X = 2.1
Child's ticket costs $2.1
LCM is found by finding the factors of both and making sure that both are inthere
9=3 times 3
12=2 times 2 times 3
common one is 3
so we have to have at least 2 threes and 2 twos
2 times 2 times 3 tiimes 3=36
answer is 36
