Answer:
Start by using your first factor, 1. Substitute "1" for each "x" in the equation: (1)3 - 4(1)2 - 7(1) + 10 = 0.
This gives you: 1 - 4 - 7 + 10 = 0.
Because 0 = 0 is a true statement, you know that x = 1 is a solution.

Samia y su hija fueron a una obra de teatro musical, ella pago $90 por su boleto y $45 por el de su hija. Ese dia el cajerovendio 100 boletos y cuenta con $8190, pero necesita saber cuantos adultos y menores de edad entraron al evento?
Answers
Answer:
Al evento entraron 82 adultos y 18 menores de edad.
Step-by-step explanation:
De acuerdo a la información proporcionada, puedes plantear las siguientes ecuaciones:
x+y=100 (1)
90x+45y=8190 (2), donde:
x es el número de adultos
y es el número de menores de edad
Puedes despejar x en (1):
x=100-y (3)
Después, puedes reemplazar (3) en (2):
90(100-y)+45y=8190
9000-90y+45y=8190
9000-8190=90y-45y
810=45y
y=810/45
y=18
Ahora, puedes reemplazar el valor de y en (3) para encontrar x:
x=100-y
x=100-18
x=82
De acuerdo a esto, la respuesta es que al evento entraron 82 adultos y 18 menores de edad.

Answer:
x = 6, y = -7 or (6, -7)Step-by-step explanation:
Given system of equations
5x+4y=2 3x+3y=-3Solving as follows:
Simplify the second equation by dividing all terms by 3
3x+3y=-3 divide by 3⇒ x + y = -1Now, considering the coefficient of x of 5 in the first equation, we will multiply the simplified second equation by 5 and subtract from the first equation:
x + y = -1 multiply by 5⇒5x + 5y = -5Subtract it from 5x + 4y = 2
5x + 4y - 5x - 5y = 2 - (-5)-y = 7y = -7Finding x using simplified second equation:
x + (-7) = -1x = - 1 + 7x = 6Answer is (6, -7)

The first two terms in an arithmetic progression are -2 and 5. The last term in the progression is the only number in the progression that is greater than 200. Find the sum of all the terms in the progression.
Answers
Given:
The first two terms in an arithmetic progression are -2 and 5.
The last term in the progression is the only number in the progression that is greater than 200.
To find:
The sum of all the terms in the progression.
Solution:
We have,
First term : [tex]a=-2[/tex]
Common difference : [tex]d = 5 - (-2)[/tex]
[tex]= 5 + 2[/tex]
[tex]= 7[/tex]
nth term of an A.P. is
[tex]a_n=a+(n-1)d[/tex]
where, a is first term and d is common difference.
[tex]a_n=-2+(n-1)(7)[/tex]
According to the equation, [tex]a_n>200[/tex].
[tex]-2+(n-1)(7)>200[/tex]
[tex](n-1)(7)>200+2[/tex]
[tex](n-1)(7)>202[/tex]
Divide both sides by 7.
[tex](n-1)>28.857[/tex]
Add 1 on both sides.
[tex]n>29.857[/tex]
So, least possible integer value is 30. It means, A.P. has 30 term.
Sum of n terms of an A.P. is
[tex]S_n=\dfrac{n}{2}[2a+(n-1)d][/tex]
Substituting n=30, a=-2 and d=7, we get
[tex]S_{30}=\dfrac{30}{2}[2(-2)+(30-1)7][/tex]
[tex]S_{30}=15[-4+(29)7][/tex]
[tex]S_{30}=15[-4+203][/tex]
[tex]S_{30}=15(199)[/tex]
[tex]S_{30}=2985[/tex]
Therefore, the sum of all the terms in the progression is 2985.
