Answer:
(3, 6)
Step-by-step explanation:
1. If any factors can be cancelled out, then this indicates that there are holes in the graph.
2. To find the x-coordinate of the hole, set the factor equal to zero and solve for x.
3. Find the y-coordinate by substituting the x-coordinate back into the "reduced" function.
Here are the steps:
[tex]f(x) = \dfrac{ { x }^{ 2 } -9 }{ x-3 }[/tex]
Factor the top part of the function
x² - 9
Since both terms are perfect squares, factor using the difference of squares formula, a² - b² = (a + b) (a - b) where a = x and b = 3
(x + 3) (x - 3)
Now that we have the top part of the function factored, we can solve the rest of the problem:
[tex]f \left( x \right) = \dfrac{ \left( x+3 \right) \left( x-3 \right) }{ x-3 }[/tex]
Set the factor "x - 3" equal to zero and solve for x
x - 3 = 0
Add 3 to both sides
x - 3 + 3 = 0 + 3
Simplify
x = 3
Now we need to solve for "y"
[tex]f \left( x \right) = \dfrac{ \left( x+3 \right) \left( x-3 \right) }{ x-3 }[/tex]
We change "f(x)", to "y"
[tex]y = \dfrac{ \left( x+3 \right) \left( x-3 \right) }{ x-3 }[/tex]
The two "x - 3" cancel out
y = x + 3
Substitute the x-value into the equation
y = 3 + 3
Add 3 and 3
y = 6
Now that we have our coordinates, we can write it as:
(x, y) = (3, 6)
So the answer is (3, 6)

Delicious Doing caterers events at a flat rate $500 plus $100 per hour after the first 2 hours. Cathy's Catering has a flat rate of $620 per event plus $70 per hour after the first three hours. What is the most amount of hours you could hire Cathy's Catering for and it cost less than Delicious Doings? Write an inequality that could be used to solve this problem
Answers
Answer:
3 hours
Step-by-step explanation:
Let the number of hours worked = x
Delicious Doing caterers events at a flat rate $500 plus $100 per hour after the first 2 hours.
$500 + $100 × x
500 + 100 × 1
After the first 2 hours = $500 + $100
= $600
After the first 3 hours = $500 + $100 × 2
= $700
Cathy's Catering has a flat rate of $620 per event plus $70 per hour after the first three hours.
$620 + $70 × x
620 + 70x
After the first 3 hours
= $600 + $70
= $670
What is the most amount of hours you could hire Cathy's Catering for and it cost less than Delicious Doings?
The Inequality is given as:
Cathy's Catering for < Delicious Doings
620 + 70x < 500 + 100x
Collect like terms
620 - 500 < 100x - 70x
120 < 30x
120/30 < x
4 < x
Therefore, the most amount of hours the most amount of hours you could hire Cathy's Catering for and it cost less than Delicious Doings is 3 hours

Answers
Answer:
It will take 3 days for their bird feeders to contain the same amount of bird seed
Step-by-step explanation:
Let the number of days it will take their bird feeder to contain the amount of bird seed be x
For Edith, the amount of birdseeds that will be left after x days will be;
4 1/2 - 3/4(x)
= 9/2 - 3x/4
For June, the amount of birdseeds that will remain after x days will be;
3 - 1/4(x)
= 3 - x/4
Since after x days, the amount of birdseeds will be equal;
Mathematically;
9/2 - 3x/4 = 3 - x/4

what is the distance between the two points A(6,-2) and B(-2,4)

Answer:
[tex]d = 10[/tex]
Step-by-step explanation:
[tex]d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Simply plug in the 2 coordinates into the distance formula to find distance d:
[tex]d = \sqrt{(-2-6)^2+(4-(-2))^2}[/tex]
[tex]d = \sqrt{(-8)^2+(4+2)^2}[/tex]
[tex]d = \sqrt{64+(6)^2}[/tex]
[tex]d = \sqrt{64+36}[/tex]
[tex]d = \sqrt{100}[/tex]
[tex]d = 10[/tex]
Answer:
10 units
Step-by-step explanation:
( x1, y1) =A(6,-2)
(x2, y2) =B(-2,4)
Using distance formula,
AB ^2 = (x2-x1) ^2 +(y2-y1) ^2
=(-2-6)^2 +(4+2)^2
=64+36
=100
Therefore, AB=10 units

The given information in statement is
mean=μ=69
standard deviation=σ=3.5
Let X be the Ishaan's exam score
X=65
The Z score can be computed as
[tex]z=\frac{x-mean}{standard deviation}[/tex]
[tex]z=\frac{65-69}{3.5}[/tex]
z=-1.1429
z=-1.14 (rounded to two decimal places).
