Given the following matrices, what 3 elements make up the first column of the product matrix DA?
Misha Larkins [42]

We have to figure out what the product of DA is,

\begin{bmatrix}-1&2&3\\8&-4&0\\6&7&1\\ \end{bmatrix}\begin{bmatrix}1\\3\\5\\ \end{bmatrix}=\begin{bmatrix}a\\b\\c\\ \end{bmatrix}

We know that,

\begin{bmatrix}a&b&c\\d&e&f\\g&h&i\\\end{bmatrix}\begin{bmatrix}x\\y\\z\\\end{bmatrix}=\begin{bmatrix}ax+by+cz\\dx+ey+fz\\gx+hy+iz\\\end{bmatrix}

So,

a=-1\cdot1+2\cdot3+3\cdot5=-1+6+15=20

b=8\cdot1+(-4)\cdot3+0\cdot5=8-12=-4

c=6\cdot1+7\cdot3+1\cdot5=6+21+5=32

So the solution is,

a,b,c=\boxed{20,-4,32}

Hope this helps :)

Rate of change y=5x+10
frozen [14]

Answer:

5

Step-by-step explanation:

The equation y=5x+10 is given in slope-intercept form. Slope-intercept form is a way of writing the equation of a line in the format y=mx+b, such that the coefficient of the parameter (x) is the slope, and constant (b) is the y-intercept. What that essentially means is,

y = mx + b\\\\m=slope\\b = y-intercept.

The slope of a line is its rate of change, and the y-intercept is where the graph of the line intersects the y-axis. One can apply this knowledge here by saying that, the equation y=5x+10 is given in the slope-intercept form, and the coefficient (m) equals (5), therefore the slope is (5).
