Answer:

When we multiply or divide by a negative to solve an inequality, it's the same as multiplying or dividing by a negative to solve a regular equation! Just remember to multiply or divide both sides by the same quantity, then simplify! Remember, when multiplying or dividing by a negative <u>YOU MUST FLIP THE INEQUALITY SIGN.</u>

Step-by-step explanation:

You are welcome.

And I hope this helps.      :)

Answer:

Step-by-step explanation:

If you begin with an inequality and wish to solve for one of the variables, you must isolate that variable on the right side of a new inequality.  Now supposing that that variable is negative in the given inequality, and that you must change that sign to positive.  Generally you can either multiply every term in the given inequality by -1 or divide every term by -1.  In both cases you must change the direction of the inequality sign.

Example:  Given -3x > 2 + 5y, solve for x.  To do this, multiply all three terms in the inequality by (-1/3), which yields x on the left and -2/3 - (5/3)y on the right.  <em>We must reverse the direction of the inequality sign</em>, so the final answer is  x < -2/3 - (5/3)y.

Brums [2.3K]

Answer:

The  weight that separate the top 8% by 5.2605 and the weight that separate bottom 8% by 5.1195.

Step-by-step explanation:

We are given that

Mean,\mu=5.19

Standard deviation,\sigma=0.05

We have to find the two weights that separate the top 8% and the bottom 8%.

Let x1 and x2 the two weights that separate the top 8% and the bottom 8%.

Z-value for p-value =0.08 =-1.41

For 8% bottom

Z=\frac{x_1-\mu}{\sigma}=-1.41

\frac{x_1-5.19}{0.05}=-1.41

x_1-5.19=-1.41\times 0.05

x_1=-1.41\times 0.05+5.19

x_1=5.1195

For 8% top

p-Value=1-0.08=0.92

Z- value=1.41

Now,

\frac{x_2-5.19}{0.05}=1.41

x_2-5.19=1.41\times 0.05

x_2=1.41\times 0.05+5.19

x_2=5.2605

(x1,x2)=(5.1195,5.2605)

Find the missing side lengths and leave the radicals in the simplest form.
yKpoI14uk [10]

Answer:

y=\frac{9\sqrt{2} }{2} and x=9

Step-by-step explanation:

We can see that the triangle is a special triangle or isosceles triangle meaning that two angles/ two sides are the same.

y=\frac{9\sqrt{2} }{2}

To solve for x use Pythagorean Theorem.

a^2 + b^2 = c^2.

\frac{9\sqrt{2} }{2} +\frac{9\sqrt{2} }{2}=x^2\\\\\frac{81}{2} +\frac{81}{2} =x^2\\\\\frac{162}{2} =x^2\\\\x=\sqrt{\frac{162}{2} } =\sqrt{81} =9\\\\x=9
