Anna11 [10]

Answer:

x=-224/229,

y=296/229,

z=118/229

Step-by-step explanation:

-5x-7y-4z=-6

6x+2y+3z=-2

-x+2y-7z=0...........( multiple with (-5) and sum with 1st equation, mult with 6 and                    sum with 2nd equation)

______________

-x+2y-7z=0

-17y+31z=-6.....(mult with 14)

14y-39z=-2.....(mult with -17) then sum

___________

-x+2y-7z=0

-229z=-118, so here we have z=118/229.

14y-39*(118/229)=-2, from here we have y=296/229

-x+2*(296/229)-7*(118/229)=0, we get that x=-234/229

In the same way you can do this in the matrix form>>

Find the missing side lengths. Leave your answers as radicals in simplest form.
Leto [7]

9514 1404 393

Answer:

  • x = 18
  • y = 9

Step-by-step explanation:

The ratios of side lengths in a 30°-60°-90° triangle are ...

  1 : √3 : 2

In the same order, the given side lengths are ...

  y : 9√3 : x

Comparing these two sets of ratios, we see that we can make the first equal to the second by multiplying by 9:

  9(1) : 9√3 : 9(2) = y : 9√3 : x

Then y = 9·1 = 9, and x = 9·2 = 18.

The missing side lengths are x = 18, y = 9.

which expression is not equal to the expression shown? 3 to the 3rd power divided by 3 to the negative 4th power. Need the answe
Alecsey [184]

Answer:

3^{-3} ÷ 3^{4}

Step-by-step explanation:

Evaluate 3^3 ÷ 3^{-4}, then evaluate each given expression to find which of them will give us the same result.

3^3 ÷ 3^{-4}

27 ÷ \frac{1}{3^4} (recall: a^{-x} = \frac{1}{a^x}

27 ÷ \frac{1}{81}

27 * \frac{81}{1} (changing from division operation to multiplication by flipping the fraction to our right upside down)

27 * 81 = 2,187

Let's compare the expressions in the given options to the value we got above:

Option 1: 3*3⁶

= 3*729 = 2,187 (this is equal)

Option 2: 3⁷ ÷ 3⁰

= 2,187 ÷ 1 (recall: x⁰ = 1, therefore, 3⁰ = 1)

= 2,187 (this is equal)

Option 3: 3³ * 3⁴

= 27*81 = 2,187 (this is equal)

Option 4: 3^{-3} ÷ 3^{4}

\frac{1}{3^3} ÷ 81

\frac{1}{27} ÷ 81

\frac{1}{27} * \frac{1}{81} (changing from division to multiplication)

= \frac{1*1}{27*81}

= \frac{1}{2,187} (not equal)

3^{-3} ÷ 3^{4} i not equal to 3^3 ÷ 3^{-4}.

Which equation represents a nonlinear function?​
Sergeu [11.5K]

Answer:

Step-by-step explanation:

Algebraically, linear functions are polynomials with highest exponent equal to 1 or of the form y = c where c is constant. Nonlinear functions are all other functions. An example of a nonlinear function is y = x^2.
