What is the domain of the function?

(

, or

The function is undefined for
x
values when the denominator,
x

5
, is
0
; it's undefined to divide by
0
. Therefore, when
x
=

,
f
(
x
)
is undefined.
f
(

=

=

Since the domain is based on the allowed values of
x
, the domain is:
(

)

(

)
Based on the domain, we would find the range by solving for

This means when

You can see that this is the case in the graph itself:
graph{(x + 7)/(x - 5) [-73.3, 74.9, -37.07, 36.97]}
What you should notice is the horizontal asymptote at
y
=

, and the vertical asymptote at
x
=

.
Because the function is trying to reach an undefined value at those points (
x

y

), you get these "walls" that cannot be crossed, only ascended or descended from either side.

The required domain of the function is all real numbers except -5 and 7. Option C is correct.

Given that,
f(x) = (x + 6)  /[(x-7)(x+5)]

What are functions?

Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.

here,
Given function,
f(x) = (x + 6)  /[(x-7)(x+5)]
We can put any real number on the number line except 7 and -5, because at these value function gives the value as infinity.

Thus, the required domain of the function is all real numbers except -5 and 7. Option C is correct.

ILL MARK YOU BRAINLIEST To join a health club, a person must pay a $75 one-time fee plus a charge of $30 per month. This situation can be presented by an equation of the form y=mx+b, where x = the fire in months and ythe
total cost in dollars. What is the value of b in this equation?

Answers

Answer: b=75

Step-by-step explanation: Given that the health club charges $30 per month, we know that this is the "m" varible. We know this because the total value changes as the value of x changes. The value of b would therefore be $75 dollars because it is a constant and a one time fee. The person joining the health club pays an amount of money per month, as well as an initial charge of $75.

center (-1, -2) , trough point ( 6, 4)

equation of the circle

r² = (x-h)²+(y-k)², where (h, k) are the coordinate of a circle so h=-1, k=-2

r² =(x+1)²+(y+2)², but (x, y ) are coordinates for any point on the circle so x=6 and y= 4

r² =(6+1)²+(4+2)²

r²= 7² +6²

r²= 85

so the equation is

(x+1)²+(y+2)²= 85

to find the points on the circle substitute in the equation x and y

(-10+1)²+(0+2)²= 85 ; 85=85 true

so the pint on the circle is (-10, 0)

3sin60°+xcos30°.tan45°=xcot30°

Answers

Answer:

x = (6[tex]\sqrt{2}[/tex])/(4[tex]\sqrt{2}[/tex] -3)

Step-by-step explanation:

sin60 degree = [tex]\sqrt{3}[/tex] /2

cos30 degree = 1/2

tan 45 degree =  sin45 degree / cos45 degree = ([tex]\sqrt{2}[/tex]/2)/([tex]\sqrt{2}[/tex] /2) = 1

cot 30 degree = cos30 / sin30 = ([tex]\sqrt{3}[/tex] /2)/(1/2)  = [tex]\sqrt{3}[/tex]

so, let us plug the above values in the given eqution and solve for x

3([tex]\sqrt{3}[/tex] /2 ) + x(1/2) *1 = x([tex]\sqrt{3}[/tex])

3([tex]\sqrt{3}[/tex] /2 )  = x([tex]\sqrt{3}[/tex]) -x(1/2)

3([tex]\sqrt{3}[/tex] /2 )  = x(([tex]\sqrt{3}[/tex])-(1/2)) (by taking x as a common factor)

3([tex]\sqrt{3}[/tex] /2 ) = x(((2[tex]\sqrt{3}[/tex])-(1))/2))    (making the same common denominator

now devide both sides by (((2[tex]\sqrt{3}[/tex])-(1))/2))

x  = 3([tex]\sqrt{3}[/tex] /2 )  / (((2[tex]\sqrt{3}[/tex])-(1))/2))

x = 3([tex]\sqrt{3}[/tex] ) / ((2[tex]\sqrt{3}[/tex])-(1))

Round 576.558 to the nearest tenths place

Answers

Answer:

576.6

(look at the number by the 10th place and round)

The value of 576.558 after rounding to the nearest tenth-place value is

576.6.

Option A is the correct answer.

What is place value?

The place value of a number is given as:

Example:

1234.567

1 = thousand place value

2 = hundred place value

3 = tens place value

4 = ones place value

5 = tenths place value

6 = hundredths place value

7 = thousandths place value

We have,

576.558

The number in the tenth place is 5 bolded underscore.

576.558

Now,

The next value is 5 which is greater or equal to 5 so we will change the tenth place value 5 into 6.

If the next value was 4 or less we will keep the tenth place value 5 as 5.

Now,

The value of 576.558 after rounding to the nearest tenth-place value is

576.6.

Thus,

The value of 576.558 after rounding to the nearest tenth-place value is

576.6.

Option A is the correct answer.

Solve for x how you would traditionally do it with any other one-variable equation

x = 1
