Answer:
x >-6
Step-by-step explanation:
Minus 7 from 19 and you get 12. Then you get -2x < 12. Divide both sides by 2 and you get x >-6.
BAC=ABD. therefore ABD = 20°
BDA = 180° - 20° -20° = 140°
BDC = 180° - 140° = 40°
BCD = 180° - 40° - 20° = 120°
Step-by-step explanation:
First, since this is already in factored form, we can find the zeroes of this quadratic, which are -3 and -1/2. (To check, you can try plugging in these 2 values for x, and they indeed equal to zero.)
Now, we want to find the vertex. The x value would be exactly halfway between -3 and -1/2, which is -1.75. Now, we just need to evaluate it, so we can find the y value of the vertex:
(-1.75+3)(2*(-1.75)+1)
=(1.25)(-2.5)
=(-3.125)
Therefore, the vertex is at (-1.75, -3.125).
3 points define a parabola, so we can directly graph it now(graph attached to the answer).
I hope this helped.
Answer:
The answer is 250 in interest.
Step-by-step explanation:
I=prt, I=(500)(0.05)(10)
Responder:
y = -6X + 36
Explicación paso a paso:
Dados los datos:
CANTIDADES __PRECIO
5 ___ 6
4 ___ 12
3 ___ 18
2 ___24
1 ___ 30
Usando una calculadora de modelo lineal:
La ecuación del modelo lineal obtenida con una calculadora de regresión es:
y = -6X + 36
Donde y = precio; - 6 = pendiente; Intercepción = 36
Se pudo observar que como reducción en la cantidad demandada puede ser como resultado de un aumento en el precio.
