Ellason wants to solve the following system using the elimination method: 5x + 2y = 30 x + y = 8 What number should the equation

Zinaida [17]

- 2 because we obtain : - 2x - 2y = - 16 ;
We solve the system:
5x + 2y = 30
-2x - 2y = -16
_____________(+)
3x / = 14;
x = 14/3;
y = 8 - 14/3;
y = 24/3 -14/3;
y = 10/3;

The solution of the system is ( 14/3 ; 10/3 )

The length of a rectangle is 5 in. More than 3 times its width. The quadratic function f(x) = x(3x + 5) represents the area of t

True [87]

Answer: Domain of function is $R^{ + }$ or (0, $\infty$ )

Step-by-step explanation:

Assuming x as width of rectangle

so, Width = x

Question says, Length is 5in more than 3 times id width.

we write as Length = 3x+5

Therefore, Area of rectangle will be given function f(x)

f(x) = x(3x+5)

Here, It is important to notice that width and length of rectangle will always be positive values and also, area of rectangle is always positive.

we can write in equation as

$x > 0$

$f(x) > 0$

Thus, Domain of function is $R^{ + }$ or (0, $\infty$ )
