Read this I have you some hint that should help you a bit don’t mode the writing lol
Answer:
x>-1
Step-by-step explanation:
To solve this problem you must apply the proccedure shown below:
1. You have the following expression given in the problem above:
<span>7/x^2-3x - 1/x^2-9
</span>
2. When you factor the denominator, you obtain:
<span>7/x(x-3) - 1/(x+3)(x-3)
3. By simplifying the expression, you obtain:
3(2x+7)/x(x+3)(x-3)
</span> 3(2x+7)/x(x^2-9)
The answer is: 3(2x+7)/x(x^2-9)
Step-by-step explanation:
Notice that 15 squared = (3 * 5)^2 = 9 * 25 = 225.
So the area of the cornfield can be 225 square acres.
Answer:
See below
Step-by-step explanation:
<h3>Given function </h3>
<u>Another notation for same function is</u>
- y = 5x - 7, where 5 is the slope and -7 is the y-intercept
<h3>Questions
</h3>
<u>1. Is the function increasing or decreasing?
</u>
- Increasing as x has positive slope
<u>2. What is the y-intercept?
</u>
<u>3. What is the slope?
</u>
<u>4. What is f(-2)?
</u>
- f(-2) = 5(-2) - 7 = - 10 - 7 = -17
<u>5. If f(x) = 0, what is x?</u>
- f(x) = 0
- 0 = 5x - 7
- 5x = 7
- x = 7/5
- x = 1.4
