Oh: 10x + 10 < 30
Whats the graph

Answers

Answer:

See attachment

Step-by-step explanation:

The given inequality is  10x + 10 < 30.

We subtract 10 from both sides to get:

10x + 10 -10< 30-10

This simplifies to 10x < 20

Divide both sides by 10 x<3

Photo above! Find the area of this triangle (It says the answer is 405 but all I get when I do it is 810) please help!

Answers

So, the area of a triangle is base x height, divided by 2. 

When you calculated the area, you forgot to divide the answer by 2, which left you with 810. 

27 x 30 = 810 
Answer/2 is equal to the answer:
810/2 is 405. 

Hope this helps! 
the formula for the area of a triangle is 1/2(base×height)
30×27=810
810×1/2=405

Answer:

I think we're probably talking about a right triangle. So just find the adjacent side and the hypotenuse.

Step-by-step explanation:

Once we are considering x \in \mathbb{R}, the range of  \text{cos}(x) is [1, -1]. Therefore, $(42)/(41) $ is not true.

In this exercise, we may have

$\text{cos}(x)=(x)/(r) =(x)/(√(x^2 +y^2) ) $

Considering the trigonometric functions beyond the unit circle.

Or considering the definition in the right triangle:

$\text{cos}(x)=\frac{\text{adjacent}}{\text{hypotenuse}} $

So to decompose means to break down. They may be talking about breaking up the number by what "place" it's in.

example given:
1,239 = 1,000 + 200 + 30 + 9
it means to break down the number 20
