First find f+g, f-g, f-g and f\g. Then determine the domain for each function f(x)=3×+7,g(×)=×+9 (f+g)(×)=

Lemur [1.5K]

I'll do f+g, you try the others on your own and comment if you need help with them! For f+g, you're just going to add the two functions together:
$f(x)=3x+7$
$g(x)=x+9$
$(f+g)(x)=(3x+7)+(x+9)=4x+16$

A cylinder has diameter 34 m and height 27 m. A label at bottom states drawing not to scale.

Blababa [14]

Answer:

Therefore,

Volume of the cylinder is 24501.42 m³.

Step-by-step explanation:

Given:

Height of Cylinder = 27 m

Diameter, d = 34 m

$Radius = \dfrac{d}{2}=\dfrac{34}{2}=17\ m$

Volume of a Cylinder = ?

Solution:

We know that

$\textrm{Volume of a Cylinder}=\pi (Radius)^{2}\times Height$

Substituting the given values in formula we get

$\textrm{Volume of a Cylinder}=3.14 (17)^{2}\times 27=24501.42\ m^{3}$

Therefore,

Volume of the cylinder is 24501.42 m³.

Solve the system of equations - 4x + 2y = -30 and – 2x + 2y = -10 by<br> combining the equations.

I am Lyosha [343]

Answer:

(x, y) = (10, 5)

Step-by-step explanation:

We notice that the y-coefficient is the same in both equations, and that the x-coefficient is smaller in the first equation. Subtracting one equation from the other will eliminate the y-variable. Subtracting the first equation from the second will result in a positive coefficient for x.

Subtracting the first equation from the second, we have ...

(-2x +2y) -(-4x +2y) = (-10) -(-30)

2x = 20 . . . .simplify

x = 10 . . . . . divide by 2

Substituting for x in the second equation gives ...

-2(10) +2y = -10

2y = 10 . . . . add 20

y = 5 . . . . . . divide by 2

The solution is (x, y) = (10, 5).
