Answer:

we conclude that:

8\le \:-4x

The graph is also attached below.

Step-by-step explanation:

Given the inequality expression

9\le 1-4x

simplify

9\le -4x+1

Add -1 to all parts

9+(-1)\le -4x+1+(-1)

simplify

8\le -4x

Divide all parts by -4

\frac{8}{-4}\le -\frac{4x}{-4}

-2\ge \:x>-5

Thus, we conclude that:

8\le \:-4x

The graph is also attached below.

Over which interval is the graph of f(x) = one-halfx2 + 5x + 6 increasing?
kaheart [24]

Answer:

\large\boxed{x\in[-5,\ \infty)}

Step-by-step explanation:

f(x)=\dfrac{1}{2}x^2+5x+6\\\\\text{The coeficient of}\ x^2\ \text{is the positive number. Therefore the parabola is op}\text{en up}.\\\\\text{If a parabola op}\text{en up, then the graph increasing in interval}\ (h,\ \infty),\\\text{and decreasing in interval}\ (-\infty,\ h).\ \text{Where}\ h\ \text{is a first coordinate of a vertex.}\\\\\text{For}\ y=ax^2+bx+c,\ h=\dfrac{-b}{2a}.\\\\\text{We have}\ a=\dfrac{1}{2}\ \text{and}\ b=5.\ \text{Substitute:}\\\\h=\dfrac{-5}{2\left(\frac{1}{2}\right)}=-\cdot\dfrac{5}{1}=-5.

Solve for x.
statuscvo [17]

Answer:

The Answer is: x = 1.444 with repeating 4.

Step-by-step explanation:

212x - 34(2x + 5) = 38

212x - 68x - 170 = 38

212x - 68x = 38 + 170

144x = 208

x = 208/144 = 52/35 or 1.444

Proof:

212(1.444) - 34(2(1.444) + 5) = 38

306.128 - 34(7.888) = 38

306.128 -  268.192 = 37.936 or approximately 38

Hope this helps! Have an Awesome Day!!  :-)
