could someone please check these problems for me? Thank you!
1. -0.7x<-35
x<50

2. Solve by elimination
3x+4y=3
6x+8y=6
answer:0

3. find y intercept to graph
x+5y=10
answer: (0,2)(10,0)

4. use distributive law to solve
7(w-5)=-35
7w-35=-35
if i add 35 to both sides i get 0

5. Simplify
1[-61-(58-85)]
1[-61-(-27)]
1[-61+27]
-61+27
-34

    1. Doesn't the inequality sign change directions when you divide by a - sign?

    2. The lines are the same, no solution.

    3. the y intercept is 2. I am not certain why you provide the other information.

    4, 5 correct
