Use a system of equations.
(x=# of small dogs, y=# of big dogs)
x+y=9 (times by -5) -5x-5y=-45
5x+8y=51
Then add the equations together and the x's cancel.
3y=6
y=2
So he walked 2 big dogs and 7 little dogs.
Answer: first box: 1/8
second box: 4
Step-by-step explanation:
(4,-2) (6,-2) (4,1) are co ordinates for the triangle after the movement
1. The best answer is A since a solution is where 2 lines intersect. Whether or not they intersect the x or y axis is completely irrelevant (so is whether they intersect the origin).
2. y=-x+5
-x+5=1/2x+2
-x+3=1/2x
3=3/2x
2=x
y=-(2)+5
y=3
Answer: (2,3)
3. It seems like the lines are completely on top of each other (coinciding) so there are infinitely many solutions.
3000 ÷ 25 = 120
Check:
120(25) = 3000 <------------------True
