Which graph shows the solution set of x-9/7x+2<=0
S_A_V [24]
For this case we have the following inequality:
 \frac{x-9}{7x+2}  \leq 0
 Solving for the numerator we have:
 x-9 \leq 0
 x  \leq 9
 Solving for the denominator we have:
 7x+2\ \textgreater \ 0
 7x\ \textgreater \ -2
 x \ \textgreater \   \frac{-2}{7}
 Therefore, the solution is given by:
 \frac{-2}{7} \ \textless \  x  \leq 9
 The graph that shows this solution is the graphic number 3.

Simplify the expression by combining like terms if possible. If not possible select already simplified. 4a^2+2a+4a^2-5
vichka [17]
So the expression is: 4 a^{2} + 2a + 4 a^{2} - 5

You can combine like terms, which are terms that contain the same variables raised to the same power. That means you can combine the two 4 a^{2}. 4 a^{2} + 4 a^{2} = 8 a^{2} The other terms can't be combined.

Your final answer should be 8 a^{2} +2a-5.
