12h - 3 > 15h or 5 > -0.2h +10

MakcuM [25]

Given composite inequality : 12h - 3 > 15h or 5 > -0.2h +10.

Let us solve them one by one.

12h - 3 > 15h

Subtracting 12h from both sides, we get

12h-12h - 3 > 15h -12h

-3 > 3h

Dividing both sides by 3, we get

-3/3 > 3h/3

-1 > h .

Solving 5 > -0.2h +10.

Adding -0.2h on both sides, we get

5 +0.2h > -0.2h+0.2h +10.

5 +0.2h > 10.

Subtracting 5 from both sides, we get

5-5 +0.2h > 10-5.

0.2h > 5

Dividing both sides by 0.2, we get

0.2h/0.2 > 5/0.2

h > 25.

Therefore -1>h or h>25.

Solve the quadratic equation by completing the square.x ^ 2 + 16x + 59 = 0First, choose the appropriate form and fill in the bla

nikitadnepr [17]

Given:

There are given the quadratic equation:

$x^2+16x+59=0$

Explanation:

To find the value of x by using completing the square, first, we need to subtract 59 on both sides of the given equation:

So,

From the given equation:

$\begin{gathered} x^2+16x+59=0 \\ x^2+16x+59-59=0-59 \\ x^2+16x=-59 \end{gathered}$

Now,

Take half of the x term and square it:

So,

From the x term,

$\lbrack16\cdot\frac{1}{2}\rbrack^2=64$

Then,

Add 64 on both sides of the above equation.

So,

$\begin{gathered} x^2+16x=-59 \\ x^2+16x+64=-59+64 \\ x^2+16x+64=5 \\ (x+8)^2=5 \end{gathered}$

Hence, an option first is correct:

$(x+8)^2=5$

Now,

From the above square:

$\begin{gathered} (x+8)^2=5 \\ x+8=\pm\sqrt[]{5} \end{gathered}$

Then,

Subtract 8 from both sides of the equation;;

So,

$\begin{gathered} x+8=\pm\sqrt[]{5} \\ x+8-8=\pm\sqrt[]{5}-8 \\ x=\pm\sqrt[]{5}-8 \\ x=\sqrt[]{5}-8,\pm\sqrt[]{5}-8 \\ x=-5.7639,-10.236067 \end{gathered}$

Final answer:

Hence, the value of x is shown below:

$x=(-5.76,-10.24)$
