1.y<=1-3x, the slope is the number with x so -3, and the y intecept is the lone number so -1 becuase the symbol includes equal to, the graph would have a solid line that passes through (0,1) and since it is also less than the shaded region would be below the line so the answer is D
2. -1x2 = -2 +-1 = -3 which is greater than -3, the answer is A
3. y-2x =-3, -1 - 2(1) = -1-2 = -3 this is less than or equal to -3. Answer is D
4 the symbol is greater than or equal to, so it would be a solid line with the shaded portion to the right of the line, Answer is A
5. the symbol is just greater than so the line would be dotted and the answer is negative (-6) so the shaded are would be to the left of the dotted line, the answer is D
-2x/5-2=18
-2x/5-2+2=18+2
-2x/5=20
-2x/5x5=20x5
-2x=100
-2x/-2=100/-2
x=-50
Answer:
(a) show all sides to be congruent
