Answer: 21

Step-by-step explanation: When you cross multiply, you get 30x14=20w. So when you simplify that you get 420/20, which is 21.

8x-2x+3y-3y=63-27\\6x=36\\x=6\\

Plug in:

2(6)+3y=27\\12+3y=27\\3y=15\\y=5

Write story or description about what the graph shows . PLEASE HELP MY BRAIN CELLS ARE DYING
Dimas [21]

I would say something along these lines: You are walking along a path, and then someone follows you. You then jog a little faster, but the stalker is coming. You then start to run away from the stalker. You realize that you are taking too long, so you jump on a bicycle. The stalker goes in a bicycle, so you jump onto a moving train to get away from him without stopping.

The domain and range of 5x squared plus 10x what is the domain and range of f of x equals 5x squared plus 10x
liberstina [14]

Answer:

Domain:  set of all real numbers

Range:  y \geq  -5

Step-by-step explanation:

We have to find the domain and range of the function:

f(x) =5x^2+10x

This is a quadratic function, shape of a "U", that's called a parabola.

The domain is the set of x values for which the function is defined.

The range is the set of y values for which the function is defined.

Normally, any parabola in the form  ax^2+bx+c  has domain as "all real numbers". This is the case for this problem as well, thus,

Domain = set of all real numbers

Now, for the range, we have to look at the minimum value of the function. So, the range would be y values greater than or equal to the minimum number. Lets find the minimum value of this function.

We have to find the value of x for which the minimum occurs by using the formula:

x=\frac{-b}{2a} =\frac{-10}{2(5)} =-1

<em><u>Note: value of a is "5" and b is "10"</u></em>

Now, we plug this into the function to find the minimum value:

f(x)=5x^2+10x\\f(-1)=5(-1)^2 +10(-1)\\f(-1)=-5

So, the range is set of all real numbers greater than or equal to -5.
