Answer:
x = 12
Step-by-step explanation:
(6x-2) + 20 = 90
6x-2 = 70
6x = 72
72 / 6 = 12
x = 12
Answer: the number = 6
Step-by-step explanation:
<u>Let x be the number.</u>
<u>Set equation according to the information given</u>
2 + 8x = 2 × 25
<u>Simplify by multiplication</u>
2 + 8x = 50
<u>Subtract 2 on both sides</u>
2 + 8x - 2 = 50 - 2
8x = 48
<u>Divide 8 on both sides</u>
8x / 8 = 48 / 8

Answer: Choice A</h3>
The -3 out front of that function means |-3| = 3 is the amplitude, which is the largest of the four functions.
In general, the sine function is
y = A*sin(B(x-C)) + D
where |A| is the amplitude. In the first answer choice, A = -3 so |A| = |-3| = 3.
Cosine has the same format since cosine is just a phase shift of sine.

if we are simplifying, the answer is 6x⁴y²
Answer:
hay 10 billetes de 2000
hay 4 billetes de 5000
Step-by-step explanation:
Planteamos las siguientes ecuaciones...:
x= billetes de 2000
y= billetes de 5000
ecuaciones :
1) x+y = 14
2) 2000x + 5000y =40000
despejamos primera ecuacion y remplazamos en segunda :
1) x= 14-y
2) 2000(14-y) + 5000y = 40000
28000- 2000y+5000y = 40000
3000y= 40000 - 28000
y= 4
reemplazamos este valor en primera ecuacion:
x+y = 14
x+ 4= 14
x= 10
ahora reemplazamo valor de X y valor de Y
2000(10) + 5000(4) =40000
40000 =40000
hay 10 billetes de 2000
hay 4 billetes de 5000
Espero que esto te ayude
