Answer:
rational numbers between 3 and 4 are
3 = 3/1* 7/7 = 21/7
4 = 4/1* 7/7 = 28/7
thus rational numbers between 3 (21/7) and 4 (28/7) are
22/7 , 23/7 , 24/7 , 25/7 , 26/7 , 27/7
Step-by-step explanation:
Recall that if and are two rational numbers then is a rational number that lies between other numbers.
Remember, you can do anything to an equation as long as you do it to both sides
and for inequalities, if you multiply or divide both sides by a negative, you have to flip the direction of the inequality sign
so
-6y+3>9-7y
add 7y to both sides
y+3>9
minus 3 both sides
y>6

Answer:
0.15 etc.
Step-by-step explanation:
That's a quadratic, a nice parabola in vertex form.
The parabola has a positive x^2 term, so it's a CUP, concave up positive. It will have a minimum at the vertex, which is (2,5). Plot that point.
Now we need a couple of guide points to draw the usual parabola going up from both sides of its vertex. We try x=0 giving (0,9) and see that x=4 also gives 9, (4,9). Plot the parabola through those two points and the vertex and you're done.
