Answer:
Points A B D
Step-by-step explanation:
I am assuming in the plane, all the points are inside. For it to be non- collinear, I am pretty sure there has to be points not on the line. In this Case, only A C D are actually on a line. Since B is to the right of C, I don't think that will make a good line. So that is the answer I am going with.

A line with slope 12 passes through the point (-6,14)
Answer:
y = 12x + 86
Step-by-step explanation:
y = mx + b
slope is 12 so m = 12
Using (-6,14) then
14 = 12(-6) + b
14 = -72 + b
b = 72 + 14 = 86

Etsuko practices origami. The square papers she used have a side length of either 7.5 cm or 25.4 cm. Etsuko says the length of the larger paper is 32.9 cm greater than the length of the smaller paper
To find how many centimeters greater the length of the larger paper is than the length of the smaller paper, the lesser number of centimeters needs to be subtracted from the greater number of centimeters which gives the result that is 17.9cm. Etsuko is incorrect because 25.4 is greater than 7.5cm.
How much greater is the side length of the paper?The mathematical operation that would be used to determine how much greater the larger paper is compared to the smaller paper is subtraction. Subtraction is the process used to determine the difference between two or more numbers. The sign that is used to represent subtraction is -.
To subtract the numbers, the length of the longer paper would be subtracted from the shorter paper.
Difference in the length of the papers = 25.4 - 7.5 = 17.9cm
Etsuko is wrong because instead of subtracting the lengths, she added the lengths. Addition is used to determine the sum of two or more numbers.

Answer:
It's easy,
To find how many centimeters greater the length of the larger paper is than the length of the smaller paper, the lesser number of centimeters needs to be subtracted from the greater number of centimeters, which gives a result that is between 7.5 and 25.4. Etsuko is not correct because 25.4 cm is 17.9 cm more than 7.5 cm.

DF
bisects LEDG. Find the value of x. The diagram is not to scale.
Answer:
x = 6
Step-by-step explanation:
Since ray DF bisects angle EDG, angles EDF and GDF are congruent. By reflexive property of congruence, ray DF is congruent to ray DF. Since all right angles are congruent, angles FED and FGD are congruent. By AAS, triangles FED and FGD are congruent. Since corresponding parts of congruent triangles are congruent, segments EF and GF are congruent, so 8x + 42 = 15x

Molly is making a punch for the school picnic. The recipe calls for 3/4 quart of lemonade, 3 cups of cranberry juice, 4 cans of orange juice concentrate, and 5 cups of water. If Molly uses 1(2/5) quarts of lemonade, how many cups of cranberry juice will she need?
She will need 5 3/5 cups of cranberry juice to make a punch for the school if Molly uses 1 2/5 quarts of lemonade.
What are the ratio and proportion?The ratio is the division of the two numbers.
For example, a/b, where a will be the numerator and b will be the denominator.
Proportion is the relation of a variable with another. It could be direct or inverse.
Given that,
To make the recipe,
3/4 quart of lemonade and 3 cups of cranberry juice
The ratio of cranberry juice to a quart of lemonade
⇒ 3/(3/4) = 4
To make the same recipe with 1(2/5) quarts of lemonade the ratio of cranberry juice to a quart of lemonade must be maintained.
So,
4 = cranberry juice / 1(2/5)
(5/7) × cranberry juice = 4
Cranberry juice = 28/5 ⇒ 5 (3/5).
Hence "She will need 5 3/5 cups of cranberry juice to make a punch for the school if Molly uses 1 2/5 quarts of lemonade".

The slopes of the linear function f(x) = 4x-1 is 4 and of the given linear function g(x) has also slope 4 . The option that the slopes of f(x) and g(x) are same is correct.
What is slope of a linear function?The slope of a linear function is the measure of steepness of the line traced by given linear function.
If a linear function is given by line y = mx +c then the slope is m
If a linear function passes through two given points (x₁, y₁) and (x₂, y₂), then its slope is (y₂ - y₁)/(x₂ - x₁)
Given the function f(x) = 4x -1 then comparing it to the form f(x) = mx + c
Slope of f(x) = m = 4
If it is given that g(x) is increasing through (2,3) and (3,7)
Then the slope of g(x) = (7- 3)/(3-2) = 4/1 = 4
Therefore, Slopes of both f(x) ang g(x) is 4.

Step-by-step explanation:
Question attached below.
Using linear functions, we have that:
a) The rate of change for Job A is of $14, while the rate of change for Job B is of $17, and these are the hourly pay for each job.
b) The slope represent the hourly pay for each job.
c) The intercepts represent the fixed salary for each job.
d) The pay will be the same on both jobs after 25 hours, of $425, as given by the intersection point on the graph.
e) For 40 hours, the payment on Job A is of $635 and on Job B of $680, hence, due to the higher payment, Tommy should accept Job B.
What is a linear function?A linear function is modeled by the following rule:
y = mx + b
In which:
m is the slope, which is the rate of change, that is, the change in y divided by the change in x.b is the y-intercept, which is the the value of y when the function crosses the x-axis, that is, when x = 0.For this problem, the two functions are given as follows:
A(h) = 75 + 14h. (slope of 14 as when x changes by 2 y changes by 28).B(h) = 17h. (slope of 17 as when x changes by 2 y changes by 34).The functions are graphed at the end of the answer.
Hence:
a) The rate of change for Job A is of $14, while the rate of change for Job B is of $17, and these are the hourly pay for each job.
b) The slope represent the hourly pay for each job.
c) The intercepts represent the fixed salary for each job.
The pay will be equal when:
A(h) = B(h)
Hence:
75 + 14h = 17h
3h = 75
h = 25.
d) The pay will be the same on both jobs after 25 hours, of $425, as given by the intersection point on the graph.
For 40 hours, the payments are given as follows:
A(40) = 75 + 14 x 40 = $635.B(40) = 17 x 40 = $680.Hence:
e) For 40 hours, the payment on Job A is of $635 and on Job B of $680, hence, due to the higher payment, Tommy should accept Job B.

Solve each equation. log₇(2 x-3)²=2
The solution of the given logarithmic equation is 16.189.
What are the various properties of the logarithm?
Out of several properties of logarithms, some of the main properties are given below:
Product Rule
log (ab) = log a + log b
Change of base
log ₇ x = log x / log 7
Power Rule
log a² = 2 log a
Quotient Rule
log (a / b) = log a - log b
Solving the given equation log₇(2x - 3)² = 2
We are given a logarithmic expression: log₇(2x - 3)² = 2
Using properties of the logarithm, we have
log (2x - 3)² / log 7 = 2
log (2x - 3)² = 2 × log 7
2 log (2x - 3) = 1.6901
log (2x - 3) = 3.3802
Using exponential on both sides,
e^[log (2x - 3)] = e^(3.3802)
2x - 3 = 29.3766
2x = 32.3766
x = 16.189
Hence, the solution of the given equation is 16.189.

Remove parentheses from each side of the equation and combine similar terms to make it simpler.To separate the variable term on one side of the equation, use addition or subtraction.To find the variable, use division or multiplication.The common denominator can be multiplied by each side of the equation to eliminate fractions.Lets take an example of solve z for 7z – (3z – 4) = 12
Here is no multiplication or division, so this will be easy to solve
⇒ 7z – (3z – 4) = 12
⇒ 7z – 3z + 4 = 12

The fraction expression (17)/(2)g - (9)/(2)h is not the same as (9)/(2)h-(17)/(2)g.
How to subtract fractions?
We are given the fraction expression;
(17/2)g - (9/2)h
Now, the fraction (17/2) is greater than (9/2) and as such the result of the subtraction of the fractions will be positive.
Now, if we change the order of the subtraction to be;
(9/2)h - (17/2)g
This means that the result will now be negative since (9/2) is less than (17/2).
Thus, we can conclude that the expression (17)/(2)g - (9)/(2)h is not the same as (9)/(2)h-(17)/(2)g.
