First step is to factorize the given expression as follows:
2x^2 + 7x - 15 = (2x-3)(x+5)
This means that the two roots of the equation are 3/2 (or 1.5) and -5
Now, we will get r and s:
we are given that the value of r is greater than the value of s, since 1.5 is greater than -5, therefore:
r = 1.5
s = -5
Answer:
The area right side to the line
Step-by-step explanation:
2 (X-Y) > 6-Y
2X - 2Y > 6 - Y
2X -6 > Y
Y < 2X - 6
The scale factor of dilation is .
<h3>What is scale factor?</h3>
When describing an enlargement you must state by how much the shape has been enlarged or reduced.
Area of triangle B =
= 0.5 x 2 x 3
= 3 units
Area of triangle A =
= 0.5 x 4 x 6
= 12 units
Scale factor =
=
=
Hence, the scale factor of dilation is .

Answer:
La ecuación genérica para un círculo centrado en el punto (a, b), de radio R, es:
(x - a)^2 + (x - b)^2 = R^2
Entonces si miramos a nuestra ecuación:
(x + 2)^2 + (y - 3)^2 = 121
Tendremos el centro en:
(-2, 3)
el radio está dado por:
R^2 = 121
R = √121 = 11
La gráfica de esta circunferencia se puede ver en la imagen de abajo.
