What is the solution for the following system of equations?
2x + y = 7
x - 2y = 6
Answers
I got you bro!
Answer:
{x,y} = {4-1}
You might be wondering how I got this, well here are the steps:
System of Linear Equations entered :
[1] 2x + y = 7
[2] x - 2y = 6
Graphic Representation of the Equations :
y + 2x = 7 -2y + x = 6
Solve by Substitution :
// Solve equation [2] for the variable x
[2] x = 2y + 6
// Plug this in for variable x in equation [1]
[1] 2•(2y+6) + y = 7
[1] 5y = -5
// Solve equation [1] for the variable y
[1] 5y = - 5
[1] y = - 1
// By now we know this much :
x = 2y+6
y = -1
// Use the y value to solve for x
x = 2(-1)+6 = 4
Solution :
{x,y} = {4,-1}
I hope this has helped you and have a wonderful day!

Kevin went to a store that offers a 20% discount. He bought a jacket and saved $11.20 after using the coupon. What is the original price of the jacket?
Answers
Answer: $56
Step-by-step explanation:
Let the original price of the jacket be x.
Since Kevin went to a store that offers a 20% discount and bought a jacket and saved $11.20 after using the coupon.
The original price of the jacket goes thus:
20% × x = $11.20
0.2 × x = 11.20
0.2x = 11.20
x = 11.20 / 0.2
x = 56
The original price of the jacket will then be $56

please read the question in picture nd help me
Answers
Answer:
1) We know that e is an irrational number, so we usually can find it by computational methods.
[tex]e = \lim_{n \to \infty} (1 + \frac{1}{n})^n[/tex]
and we know that e accurate to 10 decimal points is:
e = 2.7182818285
2) Now we want to write the properties of the exponential and logarithmic functions.
We will write first the exponential property, and then the correspondent one for the logarithmic function.
(e^a)*(e^b) = e^(a + b)
The equivalent Ln property is:
Ln(a) + Ln(b) = Ln(a*b)
(e^a)/(e^b) = e^(a - b)
The eqivalent Ln property is:
Ln(a) - Ln(b) = Ln(a/b)
(e^a)^b = e^(a*b)
The equivalent Ln property is:
Ln(a^b) = b*Ln(a)

Find the value of x!
Answers
Answer:
x = [tex]\frac{16}{3}[/tex]
Step-by-step explanation:
Since the triangles are similar then the corresponding sides are congruent.
EF and BC are corresponding sides , then
8x - 3 = 5x + 13 ( subtract 5x from both sides )
3x - 3 = 13 ( add 3 to both sides )
3x = 16 ( divide both sides by 3 )
x = [tex]\frac{16}{3}[/tex]
Find the angle of the least positive measure (in degrees, not equal to the given measure) that is coterminal with A.
A= -647°
Answers
9514 1404 393
Answer:
73°
Step-by-step explanation:
A coterminal angle will be one that is this angle plus some multiple of 360°. We observe that the magnitude of the given value is between 360 and 720, so we can find the coterminal angle of interest by adding 720°.
-647° +720° = 73°
The least positive measure angle coterminal with A is 73°.

Un barril de petróleo equivale a 159 litros entonces si un pozo de petróleo produce 374 barriles por minuto. ¿Cuántos litros son? * 10 puntos A) 2.35 B) 4.80 C) 59 466 D) 128 345
Answers
Answer:
374 barriles equivalen a 59466 litros de petróleo.
Step-by-step explanation:
La regla de tres simple es una forma de resolver problemas de proporcionalidad entre tres valores conocidos y un valor desconocido, estableciendo una relación de proporcionalidad entre todos ellos. Es decir, lo que se pretende es encontrar el cuarto término de una proporción conociendo los otros tres. Recuerde que la proporcionalidad es una relación o razón constante entre diferentes magnitudes.
Si la relación entre las magnitudes es directa, es decir, cuando una magnitud aumenta, también lo hace la otra (o cuando una magnitud disminuye, también lo hace la otra), se debe aplicar la regla directa de tres. Para resolver una regla directa de tres, se debe aplicar:
a ⇒ b
c ⇒ x
donde a, b y c son valores conocidos, mientras x es el valor que se desea conocer. Entonces: [tex]x=\frac{c*b}{a}[/tex]
En este caso, la regla de tres se aplica de la siguiente manera: si 1 barril de petróleo equivale a 159 litros, 374 barriles a cuántos litros equivale?
1 barril ⇒ 159 litros
374 barriles ⇒ x litros
[tex]cantidad de litros =\frac{374 barriles*159 litros}{1 barril}[/tex]
cantidad de litros= 59466 litros
374 barriles equivalen a 59466 litros de petróleo.

State the domain for the following relation.{(4, -1), (3, 2), (0, -3), (1, 4)} *
A. {0, 1, 3, 4}
C. {0, 1, 2, 4}
B. {2, 3, 4, 5}
D. {0, 1, 3, 5}
Answers
Answer:
A. {0, 1, 3, 4}
Step-by-step explanation:
For a relation with elements (x, y)
The domain is the set of the x-values, that are the input values.
Here we have the relation:
{(4, -1), (3, 2), (0, -3), (1, 4)}
Here we can see that the inputs are:
4, 3, 0, and 1.
Then the domain is:
{4, 3, 0, 1}
Now let's write this in the correct order:
{0, 1, 3, 4}
The domain of the relation is: {0, 1, 3, 4}
Then the correct option is A.
Find the measure of the angle indicated in bold
Answers
Answer:
x=5
Step-by-step explanation:
hey there
the angles given are corresponding angles meaning that they are congruent
so we set up an equation
23x-5=21x+5
step 1 subtract each side by 5
5-5 cancels out
-5-5=-10
now we have
23x-10=21x
step 2 subtract each side by 23x
21x-23x=-2x
now we have
-2x=-10
step 3 divide each side by 2
-10/-2=5
so we can conclude that
x=5
