These algebraic expressions are not equivalent. Explain why they are not equivalent
Answers
Answer:
Sample Answer:
Step-by-step explanation:
The coefficients on the x2 terms cancel each other because 1 – 1 = 0.
The constant was not included.
The coefficients on the x terms were subtracted incorrectly; 8x – 6x = 2x (not negative).
Answer:
Sample Response: If you simplify the first expression, you will not get the second expression. In the first expression, the x2 terms have coefficients of 1 and -1 and, when combined, the result is 0. Also, the x terms have coefficients of 8 and -6 and, when combined, the result is 2. Finally, the constant from the first expression is not in the second expression.

find the inverse of the function f(x) = 5/6x +10
Answers
Answer:
[tex]\displaystyle f^{-1}(x)=\frac{6x-60}{5}[/tex]
Step-by-step explanation:
Inverse function
Given the function
[tex]\displaystyle f(x)=\frac{5}{6}x+10[/tex]
We find its inverse following the procedure below:
Set y=f(x)[tex]\displaystyle y=\frac{5}{6}x+10[/tex]
Multiply by 6:[tex]6y=5x+60[/tex]
Operate:[tex]5x=6y-60[/tex]
Solve for x:[tex]\displaystyle x=\frac{6y-60}{5}[/tex]
Swap variables:[tex]\displaystyle y=\frac{6x-60}{5}[/tex]
Make the new y the inverse function:[tex]\boxed{\displaystyle f^{-1}(x)=\frac{6x-60}{5}}[/tex]
This is the inverse function
write the converse of the statement below. then determine whether the statement is true or false. If false, give a counterexample. Conditional Statement: If 2 angles are corresponding in parallel lines, then they are congruent.
Answers
Answer:
Converse statement is ''If two angles are congruent, then they are corresponding angles in parallel lines''.
The converse statement is false.
Step-by-step explanation:
Statement is ''If 2 angles are corresponding in parallel lines, then they are congruent.''
Converse statement is ''If two angles are congruent, then they are corresponding angles in parallel lines''.
Consider the figure.
Here,
[tex]l||m[/tex]
As ∠1 and ∠2 are alternate interior angles,
∠1 ≅ ∠2
(if two lines are parallel then each pair of alternate interior angles is equal)
So, ∠1 ≅ ∠2 but ∠1 and ∠2 are alternate interior angles not corresponding angles.
The converse statement is false.
A polynomial has zeros of 7, 6.
What is the minimum degree of the polynomial?
Answers
(X-7)(x-6)
When we distribute that we get
x^2-13x+42
A degree is the highest exponent of a polynomial. In this case the x^2. So the answer is 2
The minimum degree of the polynomial is 2.
Given the polynomial has zeros of 7, 6 means it has total of 2 zeroes. So it has only two factors possible [tex](x-7) and (x-6)[/tex] and on multiplying these factors we finally had a polynomial of degree 2 like[tex](ax^{2} +bx+c)[/tex].
So the given polynomial be a quadratic polynomial which has degree of 2.
Hence the minimum degree of the polynomial is 2.

A group of college students are going to a lake house for the weekend and plan on renting small cars and large cars to make the trip. Each small car can hold 5 people and each large car can hold 8 people. A total of 5 cars were rented which can hold 34 people altogether. Determine the number of small cars rented and the number of large cars rented.
Answers
Answer:
2 small; 3 large
Step-by-step explanation:
Using s and L for the number of small and large cars, respectively, we have ...
5s +8L = 34 . . . . number of passengers
s + L = 5 . . . . . . . number of cars
5s +8(5 -s) = 34 . . . . substitute for L
-3s +40 = 34
-3s = -6 . . . . . . subtract 40
s = 2 . . . . . . . . divide by -2
L = 5-2 = 3
2 small cars and 3 large cars were rented.

Mrs Santos has two kinds of flowers in her garden the ratio of Lily to daisies and the garden is three to two if there are 12 lilies what is the total number of Flowers in her garden
Answers
Answer:
its 8
Step-by-step explanation:
I just did the test
The total number of Flowers in her garden are, 20
We have to given that,
Mrs. Santos has two kinds of flowers in her garden,
And, the ratio of Lily to daisies and the garden is three to two.
Here, number of lilies = 12
Since, the ratio of Lily to daisies and the garden is,
3 : 2
So, Number of Lily = 3x
3x = 12
x = 12/3
x = 4
Hence, Number of daisies = 2x = 2 × 4 = 8
So, the total number of Flowers in her garden are,
⇒ 12 + 8
⇒ 20

A newly appointment school district superintendent releases a plan for the next 20 years that affects the schools within the boundaries of the district. In this plan, there is new policy that states that if a high school has less than 100 students, then the school will be shut down. Calamanco High School has a population of 1,417 students, but it is losing students at an average rate of 109 students per year. This school used to house more than 5,000 students but the district has been struggling in recent years and losing people to more affluent nearby districts and cities. Some communities are concerned about this decreasing rate because there will be a time when the district may shut the school down. Let x represent the number of full years that the school is operational.
