Expand and simplify (2x+5y) (x-3y)

Dmitry [639]

Should be simple:

Let's take this one at a time.

2x(x-3y)

You'd get:
$2x^2-3xy$
for the first one.

2nd one:
5y(x-3y)
you'd get:
$+5xy-3y^2$

Put them both together:
$2x^2-3xy+5xy-3y^2$

Combine like terms.

Your Answer:
$2x^2+2xy-3y^2$

The reflecting dish of a parabolic microphone has a cross-section in the shape of a parabola. The microphone itself is placed on

Thank you for posting your question here at brainly. I hope the answer will help you. Feel free to ask more questions.
If we set the vertex at (0,0) then the curve goes through (30,30)

<span>y = 1/30 x^2 </span>
<span>x^2 = 30y </span>

<span>Since the parabola x^2 = 4py has its focus at y=p, 4p=30 and the mic should be 15/2 inches up from the vertex.</span>

Identify the values of m and b of the linear function y = mx + b, graphed below.

Varvara68 [4.7K]

<h2>Finding the slope and y-intercept of a line given the graph</h2><h3>Answer:</h3>

$b = 4$

$m = -\frac{1}{3}$

<h3>Step-by-step explanation:</h3>

An equation of a line written in its Slope-intercept Form, $y = mx +b$ , has $b$ as its $y$ -intercept and $m$ as its slope.

$b$ or the $y$ -intercept is the $y$ -coordinate when $x = 0$ . On the given line, we can see that when $x = 0$ , $y = 4$ . It's $y$ -intercept is the point $(0,4)$ so $b = 4$ .

The slope, $m$ , of the line can be calculated by $\frac{y_2 -y_1}{x_2 -x_1}\\$ where $x_n$ and $y_n$ is the $xy$ -coordinates of any point $n$ on the line. In the given line, we can see that $(5,3)$ is on the line so this can be point $1$ . $(0,4)$ is also on the line (yes, you can also use the $y$ -intercept in calculating the slope of the line) so this can be our point $2$ .

$m = \frac{4 -3}{0 -3} \\ m = \frac{1}{-3} \\ m = -\frac{1}{3}$

The $y$ -intercept is $b = 4$ and the slope is $m = -\frac{1}{3}$

A 48 inch board is to be cut into three pieces so that the second piece is twice as long as the first piece and the third piece

Y_Kistochka [10]

Complete question :

A 48 inch board in to be cut into three pieces so that the second piece is twice as long as the first, and the third piece in 3 times as long as the first. If x represents the length of the first, find the lengths of all three

Answer:

Length of first piece = x = 8

Length of second = 2x = 8*2 = 16

Length of third = 3x = 8 * 3 = 24

Step-by-step explanation:

Let :

Length of first piece = x

Length of second = 2x

Length of third = 3x

The total lengtb of board = 48 inches

Hence,

First + second + third = 48

x + 2x + 3x = 48

6x = 48

x = 48 / 6

x = 8

Length of first piece = x = 8

Length of second = 2x = 8*2 = 16

Length of third = 3x = 8 * 3 = 24
