All three points displayed are on the line. Find an equation relating x and y.
Answer:
y = 2x - 3
Step-by-step explanation:
The graph is a straight line, thus linear with equation
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (3, 3) and (x₂, y₂ ) = (6, 9) ← 2 points on the line
m = [tex]\frac{9-3}{6-3}[/tex] = [tex]\frac{6}{3}[/tex] = 2 , thus
y = 2x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (3, 3 ), then
3 = 6 + c ⇒ c = 3 - 6 = - 3
y = 2x - 3 ← equation relating x and y
The equation whigh relates x and y points on the graph can be expressed in slope-intercept form as y = 2x - 3
The general form of a slope - intercept equation is :
y = bx + cb = slope ; c = interceptSlope, b = Rise / Run
Rise = 9 - 3 = 6 Run = 6 - 3 = 3Slope, b = 6/3 = 2
Taking a pair of point on the graph :
(3, 3)
3 = 2(3) + c
3 = 6 + c
3 - 6 = c
c = - 3
Therefore equation can be expressed thus :

Hi!
To find the surface area, we must first find the area of all of the faces and then add them together.
Because every face is the same size, the formula will be:
6(8 x 8)
6 represents the number of faces and 8 x 8 represents the formula to find the area of each.
6(8 x 8) =
6(64) =

Answer:
If I read the question right, then the answer is -36.5.
Step-by-step explanation:
Like I said, only if I read the question right. I read it as
(-35) - 1.5.
If I'm wrong, then I'm sorry.
The product of (−35)∙(−1). (5) will be 105. It is obtained by multiplying the term one by one.
What is an arithmetic operation?It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that are +, -, ×, and ÷.
We can utilize multiplication for a number of common tasks, such as figuring out how much it will cost to buy several identical things, calculating sales tax, and figuring out area and other geometric measurements.
It is given that,
=(−35)∙(−1).5
Multiply the term step by step as
=(−35)∙(−1).5
The multiplication of two negative terms gives a positive value.
=(35)5
=105
Thus, the product of (−35)∙(−1). (5) will be 105. It is obtained by multiplying the term one by one.

Which values of x are point(s) of discontinuity? x = –6 x = –2 x = 0 x = 2 x = 4.
Discontinuity is the value of x or y for which the function is not defined. The function is discontinued at points x=0 and x=4.
What is discontinuity?The discontinuity is the value of x or y for which the function is not defined. It is represented by a blank dot at the point at which it is not defined.
The discontinuity of the function is represented by a blank dot, and it is the point where the function is not defined.
If we look in the graph, we will find that there are three blank dots, which are at:
x = -2
x = 0
x = 4
Now, since discontinuity means that the function is not defined but as we can see that the value of the function is defined at x = -2, therefore, we are left with only two options which are x=0 and x=4.
Hence, the function is discontinued at points x=0 and x=4.

if you have 3 gallons of 95% alcohol, how much pure water should be added to be able to produce 70% alcohol?
Answer: Approximately 1.0714 gallons
===========================================
Work Shown:
x = amount of pure water
3 gallons of 95% alcohol means you have 3*0.95 = 2.85 gallons of pure alcohol.
If we add on x gallons of pure water, we'll have 3+x gallons of solution
So we'll have 2.85/(3+x) representing the ratio of the amount of pure alcohol to total solution. Set this equal to 0.70 and solve for x
2.85/(3+x) = 0.70
2.85 = 0.70(3+x)
2.85 = 0.70(3)+0.70(x)
2.85 = 2.10+0.70x
2.85-2.10 = 0.70x
0.75 = 0.70x
0.70x = 0.75
x = 0.75/0.70
x = 1.07142857142858 which is approximate
x = 1.0714
So if you add about 1.0714 gallons of pure water, you'll go from 95% alcohol to 70% alcohol.

What is the slope of a line perpendicular to the line whose equation is 6x-10y=140. Fully simplify your answer.
y=14
10y=140
Divide both sides by 10.
y=
10
140
Divide 140 by 10 to get 14.
y=14
The slope of a line perpendicular is -5/3 to the line whose equation is 6x-10y = 140.
What is the slope of the line?The slope of a line is defined as the inclination of the line. It is denoted by m
Slope m = (y₂ - y₁)/(x₂ -x₁ )
Make the following equation in slope-intercept form:
y = mx + b
where m denotes the slope and (0,b) denotes the y-intercept (the point at which x = 0).
The given equation is:
6x - 10y = 140
-10y = - 6x + 140
Divided by -10 into both sides of the equation,
y = (6/10)x + 140/(-10)
y = (3/5)x -14
Here m = 3/5, b is (0,14)
The slope of this line is 3/5.
The slope of all of its perpendicular lines is (-1/m), which is the negative reciprocal of slope m.
Therefore, the slope of all perpendicular lines is (-5/3).

Suppose c and d vary inversely, and d=2 when c=17.
a. Write an equation that models the variation.
b. Find d when c=68.
Answer:
a. x - cd = 0
b. d = 1 / 2
Step-by-step explanation:
d = 2
c = 7
a.
c is inversely proportional to d,
c ∝ 1 / d
This inversely proportional need to be removed by using a variation / variable.
Let the variable be " x ".
c = x / d
Multiply d on both sides,
cd = x
x = cd
Subtract cd on both sides,
x - cd = 0
Hence, the equation is " x - cd = 0 ".
b.
By using the equation,
x - cd = 0
Add cd on both sides,
x = cd
c = 17, d = 2
x = 17 * 2
x = 34
To find d, when c = 68.
x = cd
34 = 68 * d
Divide 68 on both sides,
34 / 68 = d
1 / 2 = d
d = 1 / 2

Jane took a train traveling at an average speed of 60 mph from Boston, MA to Washington, D.C. The trip took 8 hours. On her way back to Boston, Jane decides to take an express train that travels at an average speed of 75 mph. How long will the trip home take?
Answer:
6.4 minutes
Step-by-step explanation:
The question gave us the following details:
Average speed = 60mph
Time spent on trip = 8 hours
Average speed of express train on way back = 75mph
T = distance/speed
D = distance
V = speed
T = d/v
d = v(t)
d = 60 x 8
= 480
Such that
480/75
= 6.4 hours.
That is 6 hours 40 minutes is the length of time it would take on the trip home.

Perform the function operation f(x) + g(x) and then find the domain.
Answer:
f(x) +g(x) = x^2 +x -20
domain: all real numbers
Step-by-step explanation:
The sum of two polynomial functions is found by adding the terms of each function definition:
f(x) +g(x) = (x -4) +(x^2 -16)
f(x) +g(x) = x^2 +x -20

The domain of any polynomial is "all real numbers." The set of polynomials is closed to addition, meaning the sum of any polynomials is another polynomial. The sum, too, will have a domain of "all real numbers."
