Answer:

$-\dfrac{1}{2}$

Step-by-step explanation:

In the given graph of straight line to find the slope of the line.

First we choose two points on line and then using formula to find the slope.

Formula:

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

Point on line from graph: (2,-1) and (-2,1)

$x_1\rightarrow 2$

$y_1\rightarrow -1$

$x_2\rightarrow -2$

$y_2\rightarrow 1$

Substitute the points into formula

$m=\dfrac{1+1}{-2-2}$

$m=-\dfrac{1}{2}$

Hence, The slope of the line is $-\dfrac{1}{2}$

Lana71 [14]

29035 is to the right of 0.
-1349 is to the left of 0.

so, the distance between them:

29035 - (-1349) = 29035+1349 = 30384

If the scale factor between two circles is 2x/5y, what is the ratio of their areas?

Zinaida [17]

Given that the <em>length</em> ratio between the radii of the two circles is (2 · x) / (5 · y). The ratio of the areas of the two circles is (4 · x²) / (25 · y²).

<h3>What is the area ratio of two circles?</h3>

According to the statement we know that the radius ratio between two circles. Given that the area of the circle is directly proportional to the square of its radius, then the <em>area</em> ratio is shown below:

A ∝ r²

A = k · r²

A' · r² = A · r'²

A' / A = r'² / r²

A' / A = (r' / r)²

A' / A = [(2 · x) / (5 · y)]²

A' / A = (4 · x²) / (25 · y²)

Given that the <em>length</em> ratio between the radii of the two circles is (2 · x) / (5 · y). The ratio of the areas of the two circles is (4 · x²) / (25 · y²).

Finger [1]

Answer:

p = 1/2y - 3

Step-by-step explanation:

p=x/3 and x=1/2y [replace the "x" to solve]

p = (1/2y)/3
