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

When you multiply or divide an inequality by a negative number, change the direction of the arrow

1. -0.7x<-35

x>50
