-5n - 3(1+2n) = -25
Answer:
Step-by-step explanation:
-5n-3(1+2n)= -25
-5n-3-6n= -25 Distributive property (-3*1) and (-3*2n)
-11n-3= -25 -5n-6n = -11n
+3 +3 Add 3 to both sides to leave n alone
-11n= -25
----- ----- Divide by -11 on both sides to get n alone.
-11 -11
n= -2.2727272....

Answer:
The function [tex]f(x)=x^3+\mathbf{1}x^2-\mathbf{17}x+\mathbf{15}[/tex]
Step-by-step explanation:
We have the polynomial having zeros 1,3,-5
We can write them as:
x=1,x=3,x=-5
or
x-1=0, x-3=0,x+5=0
Multiplying all terms:
[tex](x-1)(x-3)(x+5)\\=(x(x-3)-1(x-3))(x+5)\\=(x^2-3x-1x+3)(x+5)\\=(x^2-4x+3)(x+5)\\=(x^2-4x+3)+5(x^2-4x+3)\\=^3-4x^2+3x+5x^2-20x+15\\=x^3-4x^2+5x^2+3x-20x+15\\=x^3+x^2-17x+15[/tex]
So, The function [tex]f(x)=x^3+\mathbf{1}x^2-\mathbf{17}x+\mathbf{15}[/tex]
how to find linear function from tabel
Write an equation of the line in slope-intercept form.
Answer:
y=mx+b where m is the slope and b is where the line crosses the y axis.
THe line crosses the y axis at 0, 2 so 2 = b
the slope is how many units the point goes up/down and to the left/right from the y intercept. From 0, 2 to 3, 3 the point goes up 1 and over to the right 3 times. rise/run is slope so 1/3 is the slope:
y=1/3x+2
Step-by-step explanation:
Answer:
Y= -1/3x + 4
Step-by-step explanation:
Slope equation= y2 - y1/x2 -x1
Subtract 2-3/ 0-3 = -1/3
Choose an ordered pair to use for this problem. I chose 3,3.
Y-intercept equation- y = mx + b
3 = -1/3 * 3 + b
Multiply-1/3 * 3
3 = -1 + b
Add 1 to get rid of -1 and get b alone
3 + 1 = -1 + 1 +b
4= b
Now plug in your numbers to your equation.
Y= -1/3x + 4

Expand and simplify (5x^(2)+1)(2x+3)-2x(5x^(2)-3)
[tex](5x^2+1)(2x+3)-2x(5x^2-3)[/tex] when expanded and simplified gives[tex]15x^2 + 8x + 3[/tex]
What is Expanding?Expanding is the opening the brackets ( ) or { } for arithmetic operations and simplifying the expression.
How to determine this
[tex](5x^2+1)(2x+3)-2x(5x^2-3)[/tex]
Open of bracket
[tex]10x^3 + 15x^2 + 2x + 3 - (10x^3 - 6x)[/tex]
[tex]10x^3 + 15x^2 +2x + 3 - 10x^3 + 6x[/tex]
Collect like terms
[tex]10x^3 - 10x^3 + 15x^2 + 2x +6x + 3[/tex]
=[tex]15x^2 + 8x + 3[/tex]
It can not be further simplified

36+7x=64 what is the answer ?
Answer:
x=4
Step-by-step explanation:
First, you need to isolate the variable and constant terms. So, we need to get rid of 36. To do this, we need to take away 36. Now, we have to do this on the other side. 64-36 is 28. Now, the equation is 7x=28.
To isolate the variable, you divide by 7. Again, do this on the other side. 28/7 is 4. Now we have x=4.
Therefore, the correct answer is 4!

El tubo de entrada que se aplica presión de aire para operar un gato hidráulico tiene 2 cm de diámetro. El pistón de salida es de 32 cm de diámetro. ¿Qué presión de aire (presión manométrica) se tendrá de aire se que haga que con para levantar un automóvil de 1800kg?
Responder:
57288.35 kN
Explicación paso a paso:
Paso uno:
datos dados
diámetro del tubo de entrada = 2 cm = 0.02 m
área = πd ^ 2/4
área = 3.142 * 0.02 ^ 2/4
área = 0.0003142m ^ 2
A1 = 3.14 * 10 ^ -4 m ^ 2
diámetro del pistón de salida = 32cm
masa del coche = 1800 kg
peso del coche = 1800 * 10 = 18000N
carga F2 = 18000N
Segundo paso:
Se requiere la presión aplicada P2
Aplicando la ecuación de presión para un fluido incompresible tenemos
P1 = F2 / A1
P1 = 18000 / 0,0003142
P1 = 57288351.36
P1 = 57288.35 kN
