c. x menos 25 menos estilo en línea fracción 4 entre 19 fin estilo paréntesis izquierdo x menos 25 paréntesis derecho igual 3
Explicación paso a paso:
Dado lo siguiente:
Cantidad original de gasolina en el tanque de combustible = x
Gasolina consumida en el primer viaje = 25 litros
Gasolina restante después del primer viaje = (x - 25) litros
Gasolina consumida en el segundo viaje = 4/19 de lo que queda, es decir;
(4/19) * (x - 25)
Gasolina restante después del segundo viaje = 3 litros
Cantidad inicial - cantidad consumida en el primer viaje - 4/19 de la cantidad restante después del primer viaje = 3
La gasolina que queda después del segundo viaje se puede modelar mediante la ecuación:
x - 25 - 4/19 (x - 25) = 3
Answer:
desculpa mas eu não sei a resposta mais eu vou ver se posso te ajudar taaa
Remark
I'm not sure I know what you mean, but I will answer trying to interpret it so it fits the description of the question.
Step One: Set up the equation. The normal way of solving this would be to use the Cos function.
Cos(theta) = Adjacent / hypotenuse = x/8 Multiply both sides by 8
8*cos(theta) = x Theta = 35
8*cos(35) = x This is about as simple a way as is possible.
6.553 = the height of the sale.
Step Three: try using the reciprocal
1 / cos(35)= hypotenuse / adjacent
1/0.8191 = 8/x cross multiply
x = 0.8191 * 8
x = 6.553
If rectangle ABCD, defined by the coordinates A(0, 0), B(0, -4), C(-2, -4), D(-2, 0), is dilated by a scale factor of 2, with re
notsponge [240]
Answer:
D) (-2, -4).
Step-by-step explanation:
Let 
be the center of dilation. Imagine that is the center of origin of a new Cartesian Plane. What would the coordinates of point A and A' on the new plane?
Dilating 
about the "origin" of the new plane by a factor of two will give the point 
, also on the new plane.
For coordinates of A' on the original plane,
.
As a result,
.
.
.
In other words, 
is the center of dilation.
