Hey there! :)
Answer:
D : [-4, ∞)
R: [-2, ∞)
Step-by-step explanation:
Notice that one end of the graphed function has a closed circle, and one end is a line. We must use specific brackets accordingly:
[ is used for closed points.
( is used for arrows or open circles.
Therefore:
This graph goes from x = -4 towards x ⇒∞. Therefore:
D : [-4, ∞)
The range of this function goes from x = -2 towards y⇒ ∞. Therefore:
R: [-2, ∞)
Answer:
Hmmmmmm
Step-by-step explanation:
123 abc you and me now
So, 10% of 40,000 is 4,000 then we add up 40,000 and 4,000 and get 44,000. Then we need to know how much is 10% of 44,000 and it is 4,400. 44,000+4,400= 48,400 and then we just need to repeat this one more time. 48,400+4,840(10% of 48,400)= 53,240. That is the answer))))
Answer:
The value of x = 7
Step-by-step explanation:
Given the right triangle
- We know that the sum of angles of a triangle is 180°.
so
Right angle + α + β = 180°
90° + 4x+7 + 8x-1 = 180
Group like terms
Add similar elements: :4x+8x=12x
Divide both sides by 12
Therefore, the value of x = 7
