Hi! I'm just answering questions for points.
Evaluate each function for the given value of x , and write the input x and output f(x) as an ordered pair.
f(x) = (7/3)x-9 for x=3
f (3) = -2 is the output for the given input .
How can you tell whether a function is linear or not?
Looking at a function's graph will reveal if it is linear or not with the greatest ease.When a linear function is plotted on a graph, a straight line is formed. A nonlinear function is curved in some way; it does not form a straight line.f(x)= (7/3)x- 9
Put x = 3 ⇒ 7 * 3/3 - 9
⇒ 7 - 9
⇒ -2
Therefore f (3) = -2

Answer:
m<LHK = 101
Step-by-step explanation:
Ok, so the straight line is equal to 180 degrees. And we already know the side of one angle, that is 79 degrees. So, simply subtract 79 from 180, and you get 101 degrees. I took geometry last year, and this might not be the "correct" way to do it, but it is easier and you get the same correct answer

What is the rate of change? x intercept is (-1,0) and b is -4 if that helps at all
Answer:
-4
Step-by-step explanation:
In this case, rate of change will be equivalent to the gradient of the line.
Standard form of Equation of Line:
y = mx + c
where
m = Gradient
c = y - intercept
From the given information, we can substitute x = -1 and y = 0, and c = b = -4 (y-intercept) to find m (Gradient)
0 = -1m - 4
m = -4
Therefore, the rate of change is -4.

Flow proof of Corollary 4.1
The Corollary 4.1 states that , the acute angles of a right triangles are complementary.
What is Corollary ?A corollary can be defined as a theorem that follows a direct result of an another theorem. With an original theorem, a corollary can be used as a reason to proof it. There are two main corollaries which follow directly from the Triangle Angle-Sum theorem. These are defined below :
Corollary 4.1
It states that the " acute angles of the right triangle are always complementary".
Abbreviation : Acute ∠s of rt. Δ are comp.
Corollary 4.2
It states that, "there is at most only one right angle or an obtuse angle in triangle".
Flow Proof of Corollary 4.1Given : a triangle ABC, right angled at A
To Prove: ∠B and ∠C are complimentary
Proof :
step 1 : ∠A = 90°
step 2: According to angle-sum theorem
∠A + ∠B + ∠C = 180
step 3: 90 + ∠B + ∠C = 180
step 4: ∠B + ∠C = 180 - 90
step 5: ∠B + ∠C = 90
Thus, Corollary 4.1 is proved.

Solve each equation. 7+b=11(b-3)
The solution of the above equation 7 + b = 11(b - 3) is b = 4.
According to the given question.
We have a linear equation in one variable
7 + b = 11(b - 3)
Since, we have to solve the above equation for b.
As we know tha, the linear equations in one variable is an equation which is expressed in the form of ax+b = 0, where a and b are two integers, and x is a variable and has only one solution.
Thereofore, the solution of the above equation 7 + b = 11(b - 3) is given by
7 + b = 11(b - 3)
⇒7 + b = 11b - 33 ( distributive property)
⇒ 7 = 11b - b - 33 (subtract b from both the sides)
⇒ 7 = 10b -33
⇒ 7 + 33 = 10b ( adding 33 both the sides)
⇒ 40 = 10b
⇒ 40/10 = b ( dividing by 10 both the sides)
⇒ 4 = b or b = 4
Therefore, the solution of the above equation 7 + b = 11(b - 3) is b = 4.

What is a quadratic equation?The quadratic equation is given as ax² + bx + c = 0. Then the degree of the equation will be 2.
Convert the standard equation into a vertex form, then we have
x² + (b/a)x + (c/a) = 0
x² + (b/a)x + b²/4a² - b²/4a² + c/a = 0
(x + b/2a)² - b²/4a² + c/a = 0
Put h = - b/2a and k = - b²/4a² + c/a, where (h, k) be the vertex of the parabola. Then the equation will be

Suppose a family drives at an average rate of 60 miles an hour on the way to visit relatives and then at rate of 40 miles an hour on the way back. The return trip takes 1 hour longer than the trip there. Let D be the distance in miles the family traveled. How many hours did it take to drive there?
Answer:
3 hours
Step-by-step explanation:
[tex]speed = \frac{distance}{time} \\ 60 = \frac{d}{t} \\ d = 60t \\ \\ speed = \frac{distance}{time} \\ 40 = \frac{d}{t + 1} \\ d = 40(t + 1)[/tex]
Since;
[tex]d = 60t \: \: \: and\\ d = 40(t + 1) \\ [/tex]
Therefore;
[tex]60t = 40(t + 1) \\ 60t = 40t + 40 \\ 60t - 40t = 40 \\ 20t = 40[/tex]
Divide both sides by 20
[tex] \frac{20t}{20} = \frac{40}{20} \\ t = 2 \: hours[/tex]
Since the return trip took an hour longer to get back home an hour will be added to the time
[tex]t + 1 = 2 + 1 \\ = 3 \: hours[/tex]

The correct form of the partial fraction decomposition for the expression 7x+18/x^2+9x is 2/x + 5/(x + 9).
What is the Fraction?
The numerator and the denominator are the two components of a fraction. The number displayed above the fractional bar is known as the numerator. As an illustration, the numerator in 6/7 is 6. Denominator: The fractional bar's lowermost number is designated as the denominator.Here,
x ² + 9x = x (x + 9), so the partial fraction decomposition would be
(7x + 18) / (x ² + 9x) = a/x + b/(x + 9)
where a, b are some constants. To find them, multiply both sides by x ² + 9x :
7x + 18 = a (x + 9) + bx
Solve for a and b :
7x + 18 = (a + b) x + 9a
[ a + b = 7
[ 9a = 18
→ a = 2, b = 5
So
(7x + 18) / (x ² + 9x) = 2/x + 5/(x + 9)

The length of one side of the garage now is 21.9 ft.
The percent increase in the length of one side was 22.35%.
What is the area of a square?The area of a square of side s is given by s squared, that is:
A = s².
The original area was 320 ft², hence the original length was:
s² = 320
s = √(320)
s = 17.9 ft.
The area increased by 50%, hence the new area is:
A = 1.5 x 320 = 480 ft².
The current length of one side is:
s² = 480
s = √(480)
s = 21.9 ft.
The percent increase is the change divided by the initial length and multiplied by 100%, hence:
(21.9 - 17.9)/17.9 x 100% = 22.35%.
The percent increase in the length of one side was 22.35%.
