Answer:

Infinitely Many Solutions

Step-by-step explanation:

Given

\left[\begin{array}{cccccc}1&2&3&4&5&6\\7&6&5&4&3&2\\8&8&8&8&8&8\end{array}\right]

Required

Determine the type of solution

From the matrix, we have:

3 non-zero rows and 5 variables (the last column is the result)

When the number of variables is more than the number of non-zero rows, then such system has infinitely many solutions

i.e.

Variables > Non\ zero\ rows

5 > 3

Answer: 6.3093

<u>Step-by-step explanation:</u>

3^{\frac{x}{5}} = 4

ln3^{\frac{x}{5}} = ln4

\frac{x}{5} ln3 = ln4

xln3 = 5ln4

x = \frac{5ln4}{ln3}

x = 6.3093

Answer: 5, 3, \frac{1}{5}, D

<u>Step-by-step explanation:</u>

a) x ≤ 0 so, f(-5) = | -5 | = 5

   x ≤ 0 so, f(-3) = | -3 | = 3

   x > 0 so, f(5) = \frac{1}{5}

b) graph D

Answer: \frac{\pi}{12}

<u>Step-by-step explanation:</u>

 \frac{25\pi}{12} - \frac{2\pi}{}

=  \frac{25\pi}{12} - \frac{24\pi}{12}

=  \frac{\pi}{12}

What is the product of (3x+7) and (x-7) ?
sleet_krkn [62]

Answer: The product of (3x+7) and (x-7) equals 3x^2 + 28x + 49

Step-by-step explanation:

To find the product of (3x+7) and (x-7) means to multiply both variables: To multiply both variables, we first multiply 3x by the expression, x - 7, then multiply 7 by the expression, x - 7.

(3x × x) +( 3x × 7) + (7 × x) + ( 7 × 7)

= 3x^2 + 21x + 7x + 49

= 3x^2 + 28x + 49
