in order to solve these equations, you need to divide the number by the varible. so #5 is 2.5y=5. you would divide 5 by 2.5, to get 2. the answer would be y=2

Step-by-step explanation:
Answer:
Hola, antes de dar la respuesta quisiera recomendarte una app llamada m a t h w a y (sin espacios) esto te va a ayudar con preguntas sobre matematica y super rapido.
Step-by-step explanation:
(2,3) pendiente de -2
1. Usa la fórmula de la ecuación de la recta para
hallar b
y = mx + b
2. Substituye el valor de m, x y "y" en la ecuacion
3 = (-2) · (2) +b
3. Calcula para hallar el valor de b
b = 7
4. Ahora con el valor de b, calcule de nuevo
y = mx + b
3 = -2x +7
Espero esto haya ayudado en algo, sino puedes intentar buscando en el sitio que recomende.
Answer:
y≤x²+4x-1.
Step-by-step explanation:
1) to define the equation of the given graph; it is y=x²+4x-1 (its vertex is (-2;-5));
2) to define inequation accorging to the given graph (the area outside of the parabola means ≤).
Answer:
decay: a, b
growth: c, d, e, f
neither: g
Step-by-step explanation:
A function is exponential if it has the independent variable in an exponent. g(x) is a linear function, not an exponential function.
__
An exponential function is a growth function if the coefficient of the variable is positive and the base of the exponent is greater than 1. It is a decay function if the exponent is positive and the base is less than 1.
The first two functions are decay functions. The remaining four exponential functions are growth functions.
