Find the excluded value of the function Y= - 10/6x-5. The excluded value is x =??
Answer:
The excluded value is x = 5/6
Step-by-step explanation:
Here, we want to calculate the excluded value
The excluded value is simply the value of x that will make the denominator of the fraction equals zero
We have this as;
6x -5 = 0
6x = 5
x = 5/6

What is a solution for a quadratic equation?Suppose that we've a function y = f(x) such that f(x) is quadratic.
When y = 0, then the values of x for which f(x) = 0 is called solution of quadratic equation f(x) = 0
This solution gives values of x, and when we plot x and f(x), we'd see that the graph intersects the x-axis at its solution points.

factor the trinomial x^2-2x-35
Answer:
(x + 5)(x - 7)
Step-by-step explanation:
x² - 2x - 35
Now we need to find two numbers whose product will be 35 and sum or difference will be 2. They are 7 and 5.
7 x 5 =35
7 - 5 = 2
So
= x² + 5x - 7x - 35
Taking x common from 1st two terms and -7 from last two.
= x(x + 5) - 7(x + 5)
Taking (x + 5) common
= ( x + 5)(x - 7)
The trinomial x² - 2x - 35 can be factored into the product of two binomials, (x - 7) and (x + 5).
What is the Factorization?Factorization, also known as factoring, is the breakdown of one element into a product of other objects, or factors, which when multiplied together generate the original. For example, the number 21 factors into primes as 3 × 7, and the polynomial x² − 9 factors as (x+3)(x-3).
The trinomial is given in the question, as follows:
x²- 2x - 35
The trinomial x² - 2x - 35 can be factored as (x - 7)(x + 5). To see this, we can find two numbers that multiply to -35 and add up to -2. These numbers are -7 and 5.
To factor the trinomial, we write:
x² - 2x - 35 = (x - 7)(x + 5)
So, the trinomial x² - 2x - 35 can be factored into the product of two binomials, (x - 7) and (x + 5).

Z = 13
Step-by-step explanation:
Both of the angles should equal 90.
2z + 5 + 5z - 6 = 7z - 1
7z - 1 = 90
7z - 1 + 1 = 90 + 1
7z = 91
7z ÷ 7 = 91 ÷ 7
Z = 13

forty-eight female students participated in a math fair. this represents 60% of the total students that participated. how many students participated in the math fair?
If 60 percent represents the 48 students , then the total number of student is 80
What is percentage?Percentages are essentially fractions where the denominator is 100. To show that a number is a percent, we use the percent symbol (%) beside the number. For example, if you got 75 questions right out of 100 on a test (75/100), you would have scored 75%.
Represent the total number of students by x;
therefore, 60/100 × x = 48
= 60x/100 = 48
60x = 4800
divide both sides by 60
x = 4800/60
x= 80
therefore the total number of students in the math fair is 80

Answer:
sin 2 ( x ) ⋅ sin 2 ( x ) cos 2 ( x ) → sin 2 ( x ) tan 2 ( x )
Step-by-step explanation:
Assuming tan = 2 ( x ) − sin 2 ( x ) = tan 2 ( x ) sin 2 ( x ) ,
tart off by rewriting tan 2 ( x ) in to its sin ( x ) and cos ( x ) components.
sin 2 ( x ) cos 2 ( x ) − sin 2 ( x )
Next find a common denominator
(LCD:
cos 2 ( x )⋅ 1 ) sin 2( x ) cos 2 ( x ) ⋅ ( 1 1 ) − sin 2 ( x ) ⋅ cos 2 ( x ) cos 2 ( x ) → sin 2 ( x ) cos 2 ( x ) − sin 2 ( x ) cos 2 ( x ) cos 2 ( x )
Combine in to a single fraction and factor out a
sin 2 ( x) . sin 2 ( x ) − sin 2 ( x ) cos 2 ( x ) cos 2 ( x ) → sin 2 ( x) ⋅ sin 2 ( x ) cos 2 ( x )
Finally just rewrite sin 2 ( x ) ⋅ sin 2 ( x ) cos 2 ( x ) → sin 2 ( x ) tan 2 ( x )

Answer:
[tex]\frac{2}{y+1}[/tex]
Step-by-step explanation:
Factorise the denominator of the second fraction
y² - 1 = (y - 1)(y + 1) ← difference of squares
To obtain a common denominator
multiply numerator/ denominator of first fraction by (y + 1)
= [tex]\frac{2(y+1)}{(y-1)(y+1)}[/tex] - [tex]\frac{4}{(y-1)(y+1)}[/tex] ← subtract numerators leaving the common denominator
= [tex]\frac{2y+2-4}{(y-1)(y+1)}[/tex]
= [tex]\frac{2y-2}{(y-1)(y+1)}[/tex]
= [tex]\frac{2(y-1)}{(y-1)(y+1)}[/tex] ← cancel common factor (y - 1) on numerator/denominator
= [tex]\frac{2}{y+1}[/tex]

Answer:
53 degrees
Step-by-step explanation:
If r is 25 and s is 102, and if there are 180 degrees in a triangle, then you can just add to get 53.
Answer:
53
Step-by-step explanation:
Hello There!
So in this problem they give us two angles of a triangle and want us to find the missing angle
Remember the sum of all of the angles in a triangle is 180
So to find the missing angle we subtract the given angles from 180
180-25-102=53
so we can conclude that the answer is 53
