Answer:
x = -10/3
Step-by-step explanation:
−4(x−5)=−7x+10
Use the distributive property to multiply −4 by x−5.
−4x+20=−7x+10
Add 7x to both sides.
−4x+20+7x=10
Combine −4x and 7x to get 3x.
3x+20=10
Subtract 20 from 10 to get −10.
3x=−10
Divide both sides by 3.
x = -10/3
Los profesores de un colegio tienen planeado mandar 6 boletines informativos al año a cada una de las 620 familias con estudiantes en el colegio. Cada uno de los boletines informativos necesita 2 hojas de papel. El papel se vende en resmas de 500 hojas. ¿Cuál es el número mínimo de resmas de papel necesarias para imprimir los boletines del colegio durante un año?
Answer:
14.88 resmas
Step-by-step explanation:
Los maestros de una escuela planean enviar 6 boletines al año a cada una de las 620 familias con estudiantes en la escuela.
Esto significa: El número total de boletines que recibe cada familia = 6 × 620 familias
= La escuela envía 3720 boletines cada año
Cada uno de los boletines necesita 2 hojas de papel.
1 boletín = 2 hojas de papel
3720 boletines =
Cruz multiplicar
3720 boletines × 2 hojas
= Se necesitan 7440 hojas de papel en un año
El papel se vende en resmas de 500 hojas.
¿Cuál es la cantidad mínima de resmas de papel necesarias para imprimir los boletines escolares en un año?
500 hojas de papel = 1 resma
7440 hojas de papel = y
Cruz multiplicar
500 × y = 7440 × 1
y = 7440/500
y = 14.88 resmas
La cantidad mínima de resmas de papel necesarias para imprimir los boletines escolares en un año es 1488 resmas
Describe the graph of the function at its roots

Answer:
Step-by-step explanation:
g(x) = (x + 4)4(x − 9)
At x = −4, the graph touches the x–axis.
At x = 9, the graph crosses the x–axis

Step-by-step explanation:
A festival charges $3 for child admission and $5 for adult admision. At the end of the festival they have sold 779 tickets for a total of $2771. Set up and solve a system of equations to find how many child tickets and how many adult tickets were sold.
Answer:
562 child tickets were sold
217 adult tickets were sold
Step-by-step explanation:
A festival charges $3 for children admission and $5 for adult admission
At the end of the festival they have sold a total number of 779 tickets for $2771
Let x represent the child ticket
Let y represent the adult ticket
x + y= 779..............equation 1
3x + 5y= 2771..........equation 2
From equation 1
x + y = 779
x= 779 -y
Substitute 779-y for x in equation 2
3x + 5y= 2771
3(779-y) + 5y= 2771
2337 - 3y + 5y= 2771
2337 +2y= 2771
2y= 2771 -2337
2y = 434
y = 434/2
y = 217
Substitute 217 for y in equation 1
x + y= 779
x + 217= 779
x = 779-217
x= 562
Hence 562 child tickets were sold and 217 adult tickets were sold

Sarita showed the steps to solving the equation. 5 (x minus 3) + 7 (x + 4) = 73 Steps Sarita's Solution Sarita's Verification 1 5 x minus 15 + 7 x + 28 = 73 5 (5 minus 3) + 7 (5 + 4) = 73. 5 (negative 2) + 7 (9) = 73. Negative 10 + 63 = 73. 53 not-equal-to 73. 2 (5 + 7) x + (negative 15 + 28) = 73 3 12 x + 13 = 73 4 12 x + 60 5 x = 5 When Sarita tried to verify her answer, she found it was wrong. Which explains her mistake?
Answer:
Sarita’s solution is correct. She made an error in her verification. Sarita was supposed to add the 5 and 7 in the first step.
Step-by-step explanation:
Given the following equation:
The steps to solve it are:
5(x-3)+7(x+4)-73
1. Apply the Distributive property:
5x-15+7x+28=73
2. Add the like terms:
12x+13=73
3. Subtract5 13 from both sides of the equation:
12x+13-(13)=73-(13
12x=60
4. Divide both sides of the equation by 12:
12r/12 = 60/12
x = 5
To verify it, let's substitute into the equation:
5(5-3)+7(5+4)=73
Evaluating, we get:
5(2)+7(9)=73
10+63=73
73=73
Based on this, we can determine that Sarita's solution is correct, but she made an error in her verification (Observe that 5-3 is not equal to -2 )
Answer:
A. Sarita’s solution is correct. She made an error in her verification.

it takes a biker 1/2 hours to ride 8/3 miles. What is the biker's rate,in miles per hour?
Answer:
The biker is traveling at [tex]5\frac{1}{3}[/tex] miles per hour.
Step-by-step explanation:
To find the rate, in miles per hour, you must use the formula r = d/t.
(r = rate)
(d = distance)
(t = time)
[tex]\frac{8}{3}[/tex] ÷ [tex]\frac{1}{2}[/tex] = [tex]5\frac{1}{3}[/tex]

Michael said, “When I divide 6 by 3, 2, or 1, the quotient is less than or equal to 6. If I divide −6 by 3, 2, or 1, I think the quotient should be less than or equal to −6. Do you agree with him? Explain.
Yes and No, if you divide 6 by 3, 2, or 1, it will have a quotient less than 6. Dividing 6 by 3 = 2, 6 by 2 = 3, 6 by 1 = 6.
using quadratics, find the value of x.
Answer:
(x+1)+(3x+1)+(2x+4)=180 (sum od all sode of a triangle is 180)
x+1+3x+1+2x+4=180
6x+6=180
6x=180-6
x=174/6
x=66
Answer:
x = 4
Step-by-step explanation:
Using Pythagoras' identity on the right triangle.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
(3x + 1)² = (x + 1)² + (2x + 4)² ← expand all factors using FOIL
9x² + 6x + 1 = x² + 2x + 1 + 4x² + 16x + 16 , simplify right side
9x² + 6x + 1 = 5x² + 18x + 17 ( subtract 5x² + 18x + 17 from both sides )
4x² - 12x - 16 = 0 ( divide through by 4 )
x² - 3x - 4 = 0 ← in standard form
(x - 4)(x + 1) = 0 ← in factored form
Equate each factor to zero and solve for x
x - 4 = 0 ⇒ x = 4
x + 1 = 0 ⇒ x = - 1
However, x > 0 thus x = 4

-2,-7,-12 ,.... is an arithmetic sequence Find the sum of its first 20 terms ?
Given sequence:
-2,-7,-12 ,..
Unknown;
Find the sum of the first 20 terms = ?
Solution:
The sequence is -2,-7,-12 ,..
To find he sum of n-terms of a sequence, we use the expression below;
Sₙ = [tex]\frac{n}{2} (2a + (n-1)d)[/tex]
where n is the number of terms = 20
a is the first term = -2
d is the common difference= -7 - (-)2 = -5
Now input the parameters and solve;
Sₙ = [tex]\frac{20}{2} (2(-2) + (20 - 1) x -5)[/tex]
Sₙ = 10(-4 + -5(19)) = 10(-99) = -990
The sum of the first 20 terms of the sequence is -990
