Answer:
x² +2x -3 = 0
Step-by-step explanation:
Given the zeros of a quadratic function the factored form is easily found. There is a factor (x -p) for each zero x = p. Here, the factored form of the function is ...
0 = (x -(-3))(x -1) = (x +3)(x -1)
In standard form, this is ...
x(x -1) +3(x -1) = 0
x² +2x -3 = 0 . . . . . . the terms have no common factors

Answer:
C. -16.25 inches
Step-by-step explanation:
First, we need to find out the total rainfall in the three days
0.75 + 0.75 + 0.75 = 2.25
Now, we need to subtract this number from 18.5
18.5 - 2.25 is 16.25
So, your answer is -16.25

The cost of renting a car for one day is $39 plus 15 cents per mile driven. In a graph of the situation, what does the cost per mile driven represent?
Answer:
It will represent the slope of the graph
Step-by-step explanation:
Here, we are interested in getting what the cost per mile driven represent
From the information, we can represent the cost as;
C = 15d + 39
In this case we have a representation of the cost using the fixed daily cost(y-intercept) and the cost depending on the number of miles driven which will change based on the number of miles.
Since it is changing, it represents the slope of the function for cost

The LaSalle High School senior class raised funds for an end of the year cruise getaway. The city gave them a special package for the port fees and taxes - a flat fee of $1,500 for the entire class's port fees and taxes. It costs $367 per student to board the cruise. If your class raised $16,600, how many students can attend?
HELP ME ASAP if ure not sure please dont answer
Answer:
Depends on what you think your instructor is looking for either it is 45 students, or the answer is 41.
Step-by-step explanation:
41 is the answer if you subtract the port fees from the amount raised then divided the remainder by cost per student .
AB, CD, and EF intersect at O. If CD is perpendicular to EF and m
Answer:
m(∠AOF) = 148°
Step-by-step explanation:
From the figure attached,
CD intersects line EF at a point O.
Line CD is perpendicular to the line EF.
m(∠AOE) = 32°
m(∠COE) = 90°
Since m(∠COE) = m(∠AOE) + m(∠AOC) = 90°
32° + m(∠AOC) = 90°
m(∠AOC) = 90° - 32° = 58°
m(∠AOF) = m(∠AOC) + m(∠COF)
= 58° + 90°
= 148°
Therefore, m(∠AOF) = 148° will be the answer.

Among all pairs of numbers with a sum of 39, find the pair whose product is maximum. Write your answers as fractions reduced to lowest terms
Answer:
39/2, 39/2 give a maximum product.
Step-by-step explanation:
Let 1 number be x then the other is 39-x.
Product P = x(39 - x)
= 39x - x^2.
Finding the derivative:
dP/dx = 39 - 2x
When P is a maximum or minimum dP/dx = 0, so
39 - 2x = 0
x = 39/2.
The 2 numbers are both 39/2.

Circle the irrational number in the list below. 7.27, 5, 9215, 2196
Answer:
7.27 is the irrational number
Step-by-step explanation:
7.27 can not turn into a fraction because it keeps on repeating
There are no Irrational numbers in the list.
We have a set of numbers - 7.27, 5, 9215, 2196.
We have to circle out the Irrational ones.
What are Irrational Numbers?Irrational numbers are the set of real numbers that cannot be expressed in the form of a fraction - p/q where p and q are integers.
According to the question, we have -
7.27, 5, 9215, 2196
Now -
7.27 = [tex]$\frac{727}{100}[/tex] → It is Rational.
5 = [tex]$\frac{5}{1}[/tex] → It is Rational.
9215 = [tex]$\frac{9215}{1}[/tex] → It is Rational.
9215 = [tex]$\frac{2196}{1}[/tex] → It is Rational.
All the numbers are Rational as they can be expressed in the form of p/q.
Hence, there are no Irrational numbers in the list.

The ratio of dogs to cats in a zoo choir is 4 : 3. There are 6 more dogs than cats. If another 2 cats join the choir, what will be the new ratio of dogs to cats?
Answer:
6:5
Step-by-step explanation:
c = number of cats
d = number of dogs
d = c+6
Set up a ratio:
4/3 = d/c
Then replace d with c+6, so your equation only has one variable.
[tex]\frac{4}{3} = \frac{c+6}{c}[/tex]
Cross multiply
4c = 3(c+6)
Multiply everything in the parentheses by 3.
4c = 3c + 18
Subtract 3c from both sides
4c - 3c = 18
c = 18
d = c + 6 = 18 + 6 = 24
If 2 more cats join, then you will have 20 cats and 24 dogs, so the ratio of dogs to cats will now be 24:20. Divide each side by 4 for a ratio of 6:5.
