Answer:

[tex] X =

\begin{bmatrix} - 4 & 1 \\ - 2 & - 7\end{bmatrix}[/tex]

Step-by-step explanation:

[tex] \begin{bmatrix} - 1 & - 2\\ 4 & 8\end{bmatrix} +X = \begin{bmatrix} - 5 & - 1\\ 2 & 1\end{bmatrix}[/tex]

[tex] X =

\begin{bmatrix} - 5 & - 1\\ 2 & 1\end{bmatrix}-\begin{bmatrix} - 1 & - 2\\ 4 & 8\end{bmatrix}[/tex]

[tex] X =

\begin{bmatrix} - 5-(-1) & - 1-(-2)\\ 2-4 & 1-8\end{bmatrix}[/tex]

[tex] X =

\begin{bmatrix} - 5+1 & - 1+2\\ 2-4 & 1-8\end{bmatrix}[/tex]

[tex] X =

\begin{bmatrix} - 4 & 1 \\ - 2 & - 7\end{bmatrix}[/tex]

Can someone help me answer these two questions

Answers

Answer:

C) 7=y=5x+11

B) m=-4/5, b=13/5

Step-by-step explanation:

Problem 1:

A function is linear if its slope is constant and/or its graph is straight (that means 1-degree polynomials only). Therefore, C is the only correct answer.

Problem 2:

Convert to slope-intercept form (y=mx+b):

4x+5y=13

5y=13-4x

y=13/5-4/5x

y=-4/5x+13/5

Now we can see that since the original equation is in slope-intercept form (y=mx+b), the slope, m, is -4/5, and the y-intercept, b, is 13/5, making option B the correct answer.

Step-by-step explanation:

[tex]a^{m}*a^{n}=a^{m+n}\\\\\frac{a^{m}}{a^{n}}=a^{m-n}\\\\(a^{m})^{n}=a^{m*n}\\\\a) 3^{5}*3^{x} = 3^{3}*9=3^{3}*3^{2}\\\\ 3^{5+x} =3^{3+2}[/tex]

Compare the exponents,

5 +x = 5

     x = 5-5

      x = 0

[tex]b) \frac{4^{x}*4^{8}}{4^{2}}=(4^{7})^{1}\\\\4^{x+8-2}=4^{7*1}\\4^{x + 6}=4^{7}[/tex]

Compare the exponents,

x +6 = 7

    x = 7-6

    x = 1

[tex]c)\frac{a^{8}*a^{5}}{a^{2}}=\frac{a^{x}}{a^{2}}\\\\a^{8+5-2}=a^{x-2}\\\\a^{11}=a^{x-2}[/tex]

Compare the exponents,

x - 2 = 11

     x = 11+2

    x = 13

[tex]d)\frac{(5^{3})^{x}}{5^{6}}=5^{10}*5^{8}\\\\5^{3x-6}=5^{10+8}\\\\5^{3x-6}=5^{18}[/tex]

Compare the exponents,

3x -6= 18

3x = 18 + 6

3x = 24
