Answer:
- At least 10 hours
- No more than 7 feet
- At least $7.5
- More than 3 players
Step-by-step explanation:
1.
- 20x + 100 ≥ 300
- 20x ≥ 200
- x ≥ 200/20
- x ≥ 10
At least 10 hours
2.
- 2(8 + x) ≤ 30
- 8 + x ≤ 15
- x ≤ 15 - 8
- x ≤ 7 feet
No more than 7 feet
3.
- 8x + 20 ≥ 80
- 8x ≥ 60
- x ≥ 60/8
- x ≥ 7.5
At least $7.5
4.
- 3(p + 3) > 18
- p + 3 > 18/3
- p + 3 > 6
- p > 6 - 3
- p > 3
More than 3 players
He can make an infinite number of different polygons,
as long as each one has more than 3 sides.
If the polygon has four sides, then it's always a parallelogram
and a rectangle, and it might also be a square.
Step-by-step explanation:
Ok. First of all, we need to follow the order of operations: Parentheses, Exponents, Multiplication, Division, Addition, Subtraction. We don't have any parentheses, exponents, or division to resolve, so you can skip those. So now you have: Multiplication, Addition, and Subtraction. We have multiplication in each term, but each term is fully simplified, so we have Addition and Subtraction left.
With that out of the way, let's go ahead and rearrange this equation so it is easier to solve. (<em>Note: we can only rearrange terms that are positive because subtraction is not commutative. But we can turn negative terms into "positive" terms by the method shown below.</em>)
4a - 7b + 2ab - a + b
4a + (-7b) + 2ab + (-a) + b (<em>Now the terms are all positive, so we can rearrange them, but they still have the same value.</em>)
4a + (-a) + 2ab + (-7b) + b
3a + 2ab + 7b
And there we go. Our answer is fully simplified. If you can understand this, you'll be able to simplify without isolating and rearranging the terms each time.
Hopefully this was helpful and not confusing.
The conclusions that can be drawn about f–1(x) are:
has an x-intercept of (-36, 0)- has a range of all real numbers.
<h3>Calculations and Parameters:</h3>
Given:
To find x, we would multiply both sides by -2/3
= 
Therefore, has an x-intercept of (-36, 0)
Furthermore, has a range of all real numbers.
