Answer:

=

Step-by-step explanation:

A half rest is 2 beats, a quarter rest is 1 beat, so the rests on the left total 3 beats.

The half note on the right is normally 2 beats, but the dot adds half-again that amount, so 1 more beat. The dotted half note on the right is 3 beats.

Both represent 3 beats, so their beat counts are "equal."

A line has a y-intercept at (0,−15) and contains the point (−4,−3). What is the equation of the line in slope-intercept form?

nydimaria [60]

Answer: $y=-3x-15$

Step-by-step explanation:

The equation of the line in Slope-Intercept form is:

$y=mx+b$

Where "m" is the slope and "b" the y-intercept.

Since the given line has a y-intercept at (0,-15), then:

$b=-15$

The formula for calculate the slope is:

$m=\frac{y_2-y_1}{x_2-x_1}$

Knowing that the given line contains the points (0,-15) and (-4,-3), we can calculate the slope. This is:

$m=\frac{-15-(-3)}{0-(-4)}=-3$

Substituting values into $y=mx+b$ , we get that the equation of the line in Slope-Intercept form is:

$y=-3x-15$

Find the determinant of the following matrix.

sineoko [7]

Answer:

$\left[\begin{array}{ccc}2&-3\\1&-4\end{array}\right]=-5$

Step-by-step explanation:

Given:

The given matrix is.

$\left[\begin{array}{ccc}2&-3\\1&-4\end{array}\right]$

the determinant of the above matrix is.

$\left[\begin{array}{ccc}2&-3\\1&-4\end{array}\right]=2\times (-4) - (-3)\times 1$

$\left[\begin{array}{ccc}2&-3\\1&-4\end{array}\right]=-8 - (-3)$

$\left[\begin{array}{ccc}2&-3\\1&-4\end{array}\right]=-8 +3$

$\left[\begin{array}{ccc}2&-3\\1&-4\end{array}\right]=-5$

Therefore, the determinant of the matrix is -5
