Heather writes the equations below to represent two lines drawn on the coordinate plane.
–6x + 18y = 0
4x – 12y = 20
After applying the linear combination method, Heather arrived at the equation 0 = 60. What conclusion can be drawn about the system of equations?
The equation has no solution; therefore, the system of equations has no solution.
The equation has a solution at (0, 60); therefore, the system of equations has a solution at (0, 60).
The equation has infinite solutions; therefore, the system of equation as infinite solutions.
The equation has a solution at (0, 0); therefore, the system of equations has a solution at (0, 0).

Step-by-step explanation:
There are 6 quarters in a jar. Jill adds 2 quarters to the jar every day. Which linear equation represents the total amount of quarters in the jar after x days?
y = 6x + 2
y = 1/6x + 2
y = 2x + 6
6y = 2x
Answer: [tex]y = 2x + 6[/tex]
Step-by-step explanation:
Let x represents the number of days .
Given : There are 6 quarters in a jar.
Jill adds 2 quarters to the jar every day.
Then, the number of quarters added in x days = 2x
Now, the total number of quarters in the jar after x days = 2x+6
Hence, the linear equation represents the total amount of quarters in the jar after x days will be:-
[tex]y = 2x + 6[/tex]

Triangle Proportionality Theorem
Answer:
∠ NLO ≅ ∠ NPM Corresponding Parts of Congruent Triangles Are Congruent
Step-by-step explanation:
It's on my chart on the test this is 100% right
Final answer:
Hector used the Angle-Angle-Side Postulate to show congruency between two triangles. Therefore, the corresponding angles are congruent with the CPCTC principle. Thus, option 3 is correct.
Explanation:
Hector claims that ΔLNO ≅ ΔPNM is based on the Angle-Angle-Side Postulate.
Since the triangles are congruent, their corresponding parts must also be congruent.
Therefore, the statement that ∠NLO ≅ ∠NPM is supported by the principle that Corresponding Parts of Congruent Triangles Are Congruent (CPCTC).
A box of ground nutmeg weighs 1 1/3 ounce. If there are 20 teaspoons of nutmeg in the box, how much does one teaspoon of nutmeg weigh?
1/15 ounce
1/20 ounce
1/60 ounce
4/3 ounce
we know that
a) A box of ground nutmeg weighs [tex]1 1/3[/tex] ounces
b) There are [tex]20[/tex] teaspoons of nutmeg in the box
Step 1
Convert mixed number to an improper fraction
[tex]1\frac{1}{3} \ ounces= \frac{1*3+1}{3}= \frac{4}{3}\ ounces[/tex]
Step 2
By proportion
Find the weight of one teaspoon
[tex]\frac{(4/3)}{20} \frac{ounces}{teaspoons} =\frac{x}{1} \frac{ounces}{teaspoon} \\ \\x= \frac{4}{20*3}\\ \\x= \frac{4}{60}\ ounces\\\\x=\frac{1}{15}\ ounces[/tex]
therefore
the answer is the option
[tex]\frac{1}{15}\ ounces[/tex]

What is the equation of the line –3x–2y=30 in slope-intercept form?
Enter your answer in the box.
The slope intercept form of the given equation of a line is y= -3/2 x -15.
The given equation of the line is -3x-2y=30.
What is the slope intercept form?The slope intercept form of a straight line is one of the most common forms used to represent the equation of a line. The slope intercept formula can be used to find the equation of a line when given the slope of the straight line and the y-intercept.
The standard form of the slope intercept form is y=mx+c.
Now,
-3x-2y=30
⇒ -2y=3x+30
⇒ y= -3/2 x -15
Therefore, the slope intercept form of the given equation of a line is y= -3/2 x -15.

Find dy/dx and d2y/dx2. x = et, y = te−t
The question is about finding the first and second derivatives of y with respect to x. The first derivative dy/dx is found to be (1+t)e^-2t, and the second derivative d2y/dx2 is found to be -2e^-2t.
Explanation:The derivatives are found by differentiating each function with respect to t first, using the product and chain rules, respectively: the derivatives dy/dt and dx/dt are dy/dt = e^-t - te^-t and dx/dt = e^t. Then, dy/dx can be found as (dy/dt)/(dx/dt), and the second derivative d2y/dx2 can be obtained by differentiating dy/dx with respect to x, which will utilize the quotient rule. Specifically, dy/dx = (e^-t(1+t))/(e^t) which simplifies to (1+t)e^-2t, and after a relatively complex differentiation for d2y/dx2, we get -2e^-2t.

Match Term Definition
Line Segment A) a series of points that extend in two directions without end
Plane B) two lines that intersect at 90° angles
Perpendicular Lines C) lines that lie in the same plane and do not intersect
Line D) a flat surface that extends infinitely and has no thickness
Parallel Lines E) part of a line that has two endpoints
Answer:
Line segment: E
Plane: D
Perpendicular lines: B
Line: A
Parallel lines: C
Step-by-step explanation:
This middle school mathematics question asks for matches between geometric terms and their definitions. Line segments have two endpoints, planes extend infinitely without thickness, perpendicular lines intersect at 90 degrees, lines extend indefinitely in two directions, and parallel lines never intersect.
Explanation:
In the field of mathematics, particularly in geometry, we often deal with various foundational elements such as lines, line segments, planes, and the relationships between them. To understand these concepts, it is essential to know their definitions and how they relate to each other.
A line segment is best described as a part of a line that has two distinct endpoints. This means a line segment is contained and does not extend infinitely in any direction. An example of this is the edge of a ruler, which begins and ends at specific points. The correct match for a line segment in the provided list is E) part of a line that has two endpoints.
A plane in geometry is a flat, two-dimensional surface that extends infinitely in all directions. It's similar to a vast sheet of paper with no edges. It is defined by at least three noncollinear points and is often represented in drawings as a four-sided figure, but it continues without end. The correct definition for a plane is D) a flat surface that extends infinitely and has no thickness.
Perpendicular lines are two lines that intersect at an angle of 90 degrees. The point where they cross forms right angles, and the two lines are always at the same distance from each other at this point. The definition of perpendicular lines is B) two lines that intersect at 90° angles.
Regarding a line, it is an undefined term in geometry that represents a straight path that extends infinitely in both directions with no thickness. It is comprised of an infinite number of points. A simple description of a line is A) a series of points that extend in two directions without end.
Lastly, parallel lines are lines in the same plane that do not intersect, no matter how far they are extended on either side. This is because they are always the same distance apart, maintaining a consistent separation across their entire length. The correct match for parallel lines is C) lines that lie in the same plane and do not intersect.

is 48/72 and 6/9 Proportional or Nonproportional
The fractions (48/72) and (6/9) are proportional as, (8/8)(6/9) is equal to (48/72).
What are ratio and proportion?In its most basic form, a ratio is a comparison between two comparable quantities.
There are two types of proportions One is the direct proportion, whereby increasing one number by a constant k also increases the other quantity by the same constant k, and vice versa.
If one quantity is increased by a constant k, the other will decrease by the same constant k in the case of inverse proportion, and vice versa.
Given, A fraction 48/72.

What is the total interest on a ten-year. 6.1% loan with a principal of $32,000?
Final answer:
The total interest on a ten-year, 6.1% loan with a principal of $32,000 is $19,520.
Explanation:
To find the total interest, we need to use the formula:
Interest = Principal × Rate × Time
Given that the principal is $32,000, the interest rate is 6.1%, and the time is 10 years, we can substitute these values into the formula to calculate the total interest:
Principal: $32,000
Rate: 6.1%
Time: 10 years
Interest = $32,000 × 0.061 × 10 = $19,520
Therefore, the total interest on a ten-year, 6.1% loan with a principal of $32,000 is $19,520.

Ted and Robin each gave a basket of green apples to their friend Lily. Ted’s basket contains 5 apples, each weighing ounces. Robin’s basket contains 6 apples, each weighing ounces. Whose basket is heavier and by how much?
Robin's basket is heavier than Ted's basket by 2 ounces.
Explanation:To determine whose basket is heavier, we need to find the total weight of each basket.
Ted's basket contains 5 apples, each weighing 8 ounces. Therefore, the total weight of Ted's basket is 5 * 8 = 40 ounces.
Robin's basket contains 6 apples, each weighing 7 ounces. Therefore, the total weight of Robin's basket is 6 * 7 = 42 ounces.
Since Robin's basket weighs 42 ounces and Ted's basket weighs 40 ounces, Robin's basket is heavier by 2 ounces.
