How to simplify x - 15 is greater than or equal to -6

dezoksy [38]

Answer:

x is greater than or equal to 9

Step-by-step explanation:

if the inequality confuses you just pretend its an equal sign like so

x-15=-6

add 15 on both sides

x= 9

now just put the inequality back in so its

x is greater than or equal to 9

Simplify square root of 3 multiplied by the fifth root of 3.

almond37 [142]

$\bf a^{\frac{{ n}}{{ m}}} \implies \sqrt[{ m}]{a^{ n}} \qquad \qquad
\sqrt[{ m}]{a^{ n}}\implies a^{\frac{{ n}}{{ m}}}
\\\quad \\% rational negative exponent
a^{-\frac{{ n}}{{ m}}} =
 \cfrac{1}{a^{\frac{{ n}}{{ m}}}} \implies \cfrac{1}{\sqrt[{ m}]{a^{ n}}}\qquad\qquad % radical denominator
\cfrac{1}{\sqrt[{ m}]{a^{ n}}}= \cfrac{1}{a^{\frac{{ n}}{{ m}}}}\implies a^{-\frac{{ n}}{{ m}}} \\\\
$

$\bf -----------------------------\\\\
thus\qquad \sqrt{3}\cdot \sqrt[5]{3}\implies \sqrt[2]{3^1}\cdot \sqrt[5]{3^1}\implies 3^{\frac{1}{2}}\cdot 3^{\frac{1}{5}}
\\\\\\
3^{\frac{1}{2}+\frac{1}{5}}\implies 3^{\frac{7}{10}}\implies \sqrt[10]{3^7}\implies \sqrt[10]{2187}$

Suppose the constant rate of change of y with respect to x is 8.5, and the value of y is 5 when the value of x is 11. what is th

zaharov [31]

Answer:

(x, y) = (19, 73)
(x, y) = (-1, -97)
(x, y) = (11 4/17, 7)

Step-by-step explanation:

You are given a point and a slope, so you can write the linear equation relating x and y using the point-slope form of the equation for a line. That form for slope m and point (h, k) is ...

y = m(x -h) +k

For your given values, m = 8.5, and (h, k) = (11, 5), the equation relating x and y can be written ...

y = 8.5(x -11) +5

___

Evaluating this for several different x-values can be done with a spreadsheet or calculator. I like to write the function into a graphing calculator and let it do the tedious arithmetic. (See the attachment.)

However, to show you what is involved in doing this by hand, we can ...

let x = 19, then ...

y = 8.5(19 -11) +5 = 8.5·8 +5 = 73

let x = -1, then ...

y = 8.5(-1-11) +5 = 8.5·(-12) +5 = -97

____

To find the value of x for y=7, we can realize that to make y go up by 2 (from the given point of 5), we need to have x go up by 2/8.5 (from the given point of 11). That is ...

for y = 7 ...

x = 11 + 2/8.5 = 11 + 4/17 = 11 4/17

What is 2(x -3) = 7 (x+24)

amm1812

Answer:

x = -34.8

Step-by-step explanation:

<h2><u>solve the equation</u></h2>

2(x-3)

= 2x - 6

7(x + 24 )

= 7x + 168

put the equation together

2x - 6 = 7x + 168

now make x subject of formula:

2x - 7x = 168 +6

-5x = 174

x = 174/ -5
