Assuming we're dealing with
, which is the same as writing (x+2)/(-5) < 4, then the answer is choice C.
We multiply both sides by -5 and this will flip the inequality sign.
-------------------------------------
Multiplying or dividing both sides by a negative number flips the inequality sign.
An example would be saying -2x < 10 leads to x > -5
What we can do is divide both sides by -2 and flip the inequality sign, or we could follow the steps shown below
- -2x < 10
- 0 < 10+2x ... adding 2x to both sides
- -10 < 2x ... subtracting 10 from both sides; this is one way to see why the sign flip happens
- 2x > -10
- x > -10/2 ..... dividing both sides by 2
- x > -5
A. The hexagon as the series is adding a side each time. So you started with 3, 4, 5...
Answer:
Graph 4
Step-by-step explanation:
Parallel lines have no solution to the system of equation. Graph 4 is a set of parallel lines, so they will never intersect.
12x²-9x = 0
3x(4x-3)=0
4x-3=0
4x=3
x=3/4
so either x = 0 or x = 3/4
The student who said 302 is a greater number is correct because since it has a 0 it brings the number into the hundreds while 32 is a lesser value . another example would be to make 32 you would need 3 ten blocks and 2 ones blocks and to make 302 would need 3 hundreds blocks and 2 ones blocks
if 7/2 = x/81
then you cross multiply and get
2x = 567 then divide by 2 and you get
283.5 and that's your answer
