Answer:
Decrease, Increase and reflects over the y axis.
Step-by-step explanation:
the function shrinks so it would shorten the period, this frequency would then increase as well when b increases because b is the frequency. it would reflect over the y axis because when graphed it is reflected over the y axis.
-If none of this also makes sense you the answer is correct anyway because this was the correct answer on edmentum/plato.
Answer:
<em>Answer: B San Francisco</em>
Step-by-step explanation:
It can be read that Geneva is 12°C colder than Nikki's hometown. It can be seen in the table that Geneva is at -3°C.
This means that Nikki's hometown is 12°C hotter than Geneva, thus:
Temperature of Nikki's hometown = -3°C + 12°C = 9°C.
The only city with a temperature of 9°C is San Francisco.
Answer: B San Francisco
Answer:
(14 / x) = .56
Numer of questions = 25
Step-by-step explanation:
1 and3can form the triangle
As the sum of 2sides is greater then the 3rdside
Like for first one
12+14>18
26>18
Yes
14+18>12
32>12
Yes
12+18>14
30>14
Yes
so the first set of sides can become a triangle
Respuesta: 12 estudiantes trajeron pilas
Solución:
Numero total de estudiantes: 30
Sea:
x: numero de estudiantes que trajeron pilas
y: numero de estudiantes que no trajeron pilas
x+y=30 (1)
La razón entre los estudiantes que trajeron pilas y los que no trajeron es como 2 es a 3:
Razón: r=x/y=2/3 (2)
Cuantos estudiantes trajeron pilas?
x=?
Tenemos un sistema de 2 ecuaciones con 2 incógnitas:
(1) x+y=30
(2) x/y=2/3
Vamos a resolver para x. Multiplicando en cruz en la segunda ecuación:
(2) 3x=2y
Depejando y: Dividiendo ambos lados de la ecuación entre 2:
3x/2=2y/2
3x/2=y
y=3x/2
Sustituyendo y por 3x/2 en la primera ecuación:
(1) x+y=30
x+3x/2=30
Sumando los términos en el lado izquierdo de la ecuación:
(2x+3x)/2=30
5x/2=30
Despejando x:
x=30*2/5
x=60/5
x=12
