Answer:
uhm so you'd assume y is more than 5 so maybe try x +(7+1) /5
now do x + 8 /5. x must be like 7 so
x= 7 and y= 7 so it is 7 + (7+1) divided by 5 which is 3 I believe
simplifying it just as is is more like x + (y+1) / 5

HELP PLEASE!!
Answer:
x = 16
Step-by-step explanation:
hypotenuse= a /sin(α)
= 22.62742
= 16√2
So using this to calculate x:
x = √c2 - a2
= √22.627416997972 - 162
= √256
= 16
Hope this helps you :)

Answer:
x=3
y=1
Step-by-step explanation:
-2x - 7y = -13
3x + 6y = 15
3(-2x - 7y = -13) = -6x - 21y = -39
2(3x + 6y = 15) = 6x + 12y = 30
-6x - 21y = -39
---------------------- The -6x and 6x cancel out, 12 - 21 is equal to 9, 30 - 39 = -9
6x + 12y = 30
Therefore, you can say that -9y = -9 so y = 1
FInally, plug that back into either one of the original equations:
3x + 6(1) =15
3x = 9
x = 3

State the slope and y-intercept of the graph of y = 1/5 x – 7
Solve the following equation for y, and then identify the slope of the line: 5x + 9y = 8.
Answer:
equation: y=-5/9(x)+8/9 slope: y=-5/9(x)
Step-by-step explanation:
9y=8-5x
y=(8/9)-(5/9)x
y=-5/9(x)+8/9

Answer:
The circunference is represented by the equation is [tex]x^{2}+y^{2}-6\cdot x +4\cdot y +9=0[/tex].
The graph of this function is presented in the attachment.
Step-by-step explanation:
The general equation of the circunferece is defined by the following formula:
[tex]x^{2}+y^{2}+A\cdot x + B\cdot y + C = 0[/tex] (1)
We can determine the value of the coefficients by knowing three distinct points: [tex](x_{1}, y_{1}) = (3,0)[/tex], [tex](x_{2},y_{2}) = (5,-2)[/tex], [tex](x_{3},y_{3}) = (1, -2)[/tex]
The system of linear equations is:
[tex]3\cdot A + C = -9[/tex] (2)
[tex]5\cdot A -2\cdot B + C = -29[/tex] (3)
[tex]A -2\cdot B + C = -5[/tex] (4)
The solution of this system is: [tex]A = -6[/tex], [tex]B = 4[/tex], [tex]C = 9[/tex].
The circunference is represented by the equation is [tex]x^{2}+y^{2}-6\cdot x +4\cdot y +9=0[/tex].
The graph of this function is presented in the attachment.

AND THEN ONCE U HAVE THE ANSWER
FIND THE LENGTH OF AC
Answer:
AC=18
Step-by-step explanation:
To find AC, use the Pythagorean Theorem. Since the longest side (hypotenuse) is known, instead of a²+b²=c², the equation will be c²-a²=b². 12²-8²=b²
144-64=b²
80=b²
√80=√b²
8.94427191=b
That is for one of the two right triangles that make up the tent. Since there are 2 triangles, 8.94427191 only equals BC or AB. So, multiply 8.94427191×2=17.88854382 to find the length of AC.
AC= 18

Se necesita instalar el piso de una habitacion de forma rectangular cuyas dimensiones son 7 m por 8 m el piso se cubrira con baldosas cuadradas de 25 cm de lado,que cuestan 20000 el metro cuadrado. ¿ cual es el costo del material para cubrir el piso?
Answer:
Costo total= $1.120.000
Step-by-step explanation:
Dada la siguiente información:
Se necesita instalar el piso de una habitacion de forma rectangular cuyas dimensiones son 7 m por 8 m.
Costo por m2= $20.000
Primero debemos calcular el total de metros cuadrados de la habitación:
Totalm2= 7*8= 56m2
Ahora el costo total:
Costo total= 56*20.000
Costo total= $1.120.000
