Answer:

r = 2

Step-by-step explanation:

use slope formula to find r

(r, 3) (5, 9) m = 2

y₂ - y₁ / x₂ - x₁ = m (Formula)

9 - 3 / 5 - r = 2 (use the points given then subtract 9 - 3)

6 / (5 - r) = 2 / 1 [Cross Multiply--2( 5- r ) = 6 x 1 ]

10 - 2r = 6 (solve equation)

-2r = -4

r = 2

What are the diameters of the painting? Easy!!!

zalisa [80]

x = 10.22 in

Solution:

Width of the figure = x in

Length of the figure = (2x + 5) in

Area of the figure = 260 in²

To find the value of x:

Area of the figure = length × width

length × width = 260

(2x + 5) × x = 260

$2x^2+5x=260$

Subtract 260 from both sides of the equation.

$2x^2+5x-260=0$

Factor the above quadratic expression.

Quadratic equation formula:

$$x=\frac{-b \pm \sqrt{b^{2}-4 a c}}{2 a}$

$$x=\frac{-5 \pm \sqrt{5^{2}-4 \cdot 2(-260)}}{2 \cdot 2}$

$$x=\frac{-5 \pm \sqrt{2105}}{4}$

$$x=\frac{-5+\sqrt{2105}}{4}, \ x=\frac{-5-\sqrt{2105}}{4}$

x = 10.22, x = –12.72006

Dimension of the figure cannot be measured in negative terms.

Hence x = 10.22 in.
