Answer:
[-4,0) ∪ [2, ∞)
Step-by-step explanation:
For piecewise function domain and range, we need to understand the difference between "(" and "[" or ")" and "]"
- The parenthesis ( "(" and ")" ) are used for "open circles" in the graph.
- The brackets ( "[" and "]" ) are use for "closed circles" in the graph.
Range is the set of y-values for which the function is defined.
Now,
The upper part of the function shows the graph going from y = 2 towards infinity (arrow). At y = 2 , there is closed circle, so this part range would be
[2, ∞) (infinity is always with parenthesis)
Now, looking at bottom part, the function is defined from 0 (open circle) to -4 (closed). so we can write:
[-4,0)
This is the range, 2nd answer choice is correct.
[-4,0) ∪ [2, ∞)
Answer:
2/(x-3) = 4. 4x-12 = 2. x=7/2. G) 7/(2x+5) = 2/3. 21 = 4x + 10. x = 21/4. H) 7/(x-9) = 5. 7 = 5x-45. x = 52/5

Step-by-step explanation:
<u>Elasticity Demand</u>
- The flexibility of interest is a significant minor departure from the idea of interest. Request can be delegated as versatile, inelastic, or unitary.
- Flexible interest is one in which the adjustment of the amount requested because of an adjustment of cost is huge. An inelastic interest is one in which the adjustment of the amount requested because of an adjustment of cost is little.
- The equation for processing versatility of interest is:
(Q1 - Q2)/(Q1 + Q2)
(P1 - P2)/(P1 + P2)
- In the event that the recipe makes an outright worth more prominent than 1, the interest is flexible. At the end of the day, the amount changes quicker than the cost. On the off chance that the worth is under 1, the request is inelastic. All in all, the amount changes more slowly than the cost. In the event that the number is equivalent to 1, the flexibility of interest is unitary. All in all, the amount changes at a similar rate as the cost.
- An illustration of items with a flexible interest is purchaser durables. These are things that are bought inconsistently, similar to a clothes washer or an auto, and can be deferred assuming the cost rises. For instance, vehicle refunds have been extremely fruitful in expanding car deals by diminishing costs.

Answer:
3 = 45 : 5 = 75
Step-by-step explanation:
interior angles in a triangle = 180
2 sides + 60 = 180
2 sides = 180 - 60
2 sides = 120
ratio of 2 sides = 3:5
total ratio = 8
<u>3</u> x 120
8
= 45
<u>5</u> x 120
8
=75
i know there's a way to calculate that with just a pencil ,
but nobody ever uses it.
This is one of the few situations where I gladly refer you
to a calculator. There, you'll find that the angle is
(<em>26 degrees</em>) plus or minus any multiple of 180 degrees.
