the solutions to a linear equation are the points in the plane that make the inequality true .
true or false ?
Answers
The statement is false. An equation's solutions are points on a line; an inequality's solutions encompass a region on the plane.
Explanation:The statement is false. The solutions to a linear equation are the points (x, y) in the plane that make the equation true, not an inequality. An equation represents a line on the coordinate plane, and every point on that line is a solution to the equation. In contrast, an inequality describes a range or region of the coordinate plane, not just a single line, and the solutions are the coordinates within that range.
For instance, the solutions to the equation y = 2x + 3 are all the points on the line where this is true. On the other hand, solutions to the inequality y > 2x + 3 would be all the points in the region above the line y = 2x + 3.

point E is the midpoint of ab and point f is the midpoint of CD
Answers
AB is bisected by CD (TRUE). This is True because E is the midpoint between A and B and CD passes through E
CD is bisected by AB (FALSE) CD is bisected by point F and not AB
AE = 1/2 * AB (TRUE) since E is the midpoint of AB , E divides AB into two equal halves
EF = 1/2 * ED (FALSE) The true statement would have been CF = 1/2* CD
FD = EB (FALSE) sinc we do not know if CD and AB are of the same lengths
CE + EF = ED (TRUE) since F is the midpoint the sum of CE and EF is equal to ED
The statements for the line AB and CD for this condition that are true are given as:
Option A: [tex]\overline{AB}[/tex] is bisected by [tex]\overline{CD}[/tex]
Option C: [tex]AE = \dfrac{1}{2} \times AB[/tex]
Option F: CE + EF = FD
What is a bisector?A bisector of a line bisects that considered line. Bisect means to split in two equal parts.
For this case, we see that CD passes through mid point of AB, so CD is bisector of line AB or we say that line segment AB is bisected by line segment CD.
But AB does not passes through the center of AB, thus, AB is not a bisector of CD, or we say that line segment CD is not bisected by line segment AB
AE = EB
And AE + EB = AB
Thus, AE + AE + AB
or 2AE = AB
or AE = (AB)/2 = (1/2)AB
E is not necessary to be fixed on CD, it can move between C and F. Thus any statement about length of E to any point on CD is not necessary to be true.
FD is half of CD and EB is half of AB. It is not necessary that AB and CD are of same length, thus, it is not necessary that FD and EB are going to be of same length, thus, not congruent(two line segments are called congruent (denoted by ≅) if they are of same lengths).
CE + EF = CF, and CF = FD since F is midpoint.
Thus, CE + EF = FD
Thus, the statements for the line AB and CD for this condition that are true are given as:
Option A: [tex]\overline{AB}[/tex] is bisected by [tex]\overline{CD}[/tex]
Option C: [tex]AE = \dfrac{1}{2} \times AB[/tex]

Two numbers N and 16 have LCM = 48 and GCF = 8. Find N.
Answers
Final answer:
To find the number N with LCM of 48 and GCF of 8 with 16, we use the formula LCM × GCF = N × 16 which gives N = 24.
Explanation:
To find the number N when given that it has a Least Common Multiple (LCM) of 48 with the number 16 and a Greatest Common Factor (GCF), also known as the Greatest Common Divisor (GCD), of 8, we can use the relationship between LCM, GCF, and the product of the two numbers:
LCM(N, 16) × GCF(N, 16) = N × 16
Given that LCM(N, 16) = 48 and GCF(N, 16) = 8, we can substitute these values into the equation:
48 × 8 = N × 16
Solving for N:
N = × 48 × 8 / 16
N = × 24
Hence, the number N is 24.

518 feet
Answers
To convert 1,700 meters to feet, we multiply by the conversion factor of 3.28 feet per meter, resulting in a length of 5,576 feet for the train.
Explanation:To find the length of the train in feet, we need to convert meters to feet using the conversion factor provided. Given that 1 meter is approximately 3.28 feet, we can calculate the length of the train in feet by multiplying the length of the train in meters (1,700 meters) by the conversion factor (3.28 feet per meter).
The calculation would be as follows:
1,700 meters × 3.28 feet/meter = 5,576 feet
Therefore, the length of the train is 5,576 feet.
Dwayne's garden is triangle-shaped with two equal sides and a third side that is 4 ft more than the length of an equal side. If the perimeter is 49 ft, how long is each side
Answers
Where side1=side2 because 2 of the sides equal
And side3=side1+4ft because side3 is 4ft more than the length of an equal side
Plug them in
49ft=side1+side1+(side1+4ft)
simplify
Subtract 4 from both sides
45ft = side1+side1+side1
45ft = 3*side1
Divide both sides by 3
15ft = side1
Side1 =side2=15ft
Side3=side1+4ft= 15+4=19ft
Jacob drove from town a to town b at an average rate of x miles per hour, then returned along the same route at y miles per hour. if he then drove back to town b at z miles per hour along the same route, what was jacob's average rate of speed for the entire trip, in miles per hour?
Answers
= (total distance)/(time of 1st journey + time of 2nd journey + time of 3rd journey)
Let d = the distance between Town A and Town B
So, total distance traveled = 3d
Time = distance/speed
time of 1st journey = d/x
time of 2nd journey = d/y
time of 3rd journey = d/z
Total time = d/x + d/y + dz
To simplify, rewrite with common denominator: dyz/xyz + dxz/xyz + dxy/xyz
So, total time = (dyz + dxz + dxy)/xyz
Average speed = (total distance)/(total time)
= 3d/[(dyz + dxz + dxy)/xyz]
= (3dxyz)/(dyz + dxz + dxy)
Divide top and bottom by d to get: (3xyz)/(yz + xz + xy)
Find the recursive formula for the geometric sequence 5, 10, 20, 40, . . .
Answers
I believe that the repeated formula that is continuing the geometric sequence is "multiply by 2". The rule of the sequence is to multiply by 2 because the first number of the sequence is 5 and when you multiply 5 w/ 2, you get 10. After multiplying 10 w/ 2 as well, you'll get 20, which is the next number in the geometric sequence. Same goes for when you multiply 20 w/ 2. Your result would be 40. So, the recursive formula is to multiply by 2.

- Angle LOM and angle MON are complementary angles. If m∠LOM = (x + 15)° and m∠MON = 48°, which equation could be used to solve forx?
A. (x + 15)° + 48° = 180°
B. (x + 15)° = 90°
C. (x + 15)° + 90° = 48°
D. (x + 15)° + 48° = 90°
Answers
Angles that are complementary add up to 90. We know that in order to find the value of x, we'll need to create an equation. This equation would be (x + 15) + 48 = 90. This is because, together, the two angles must add up to 90.
ANSWER:
D - (x + 15) + 48 = 90
Hope this helps!! :)
If there's anything else that I can help you with, please let me know!
The correct equation to solve for x, given that angle LOM (measured as (x + 15)°) and angle MON (measured as 48°) are complementary, is (x + 15)° + 48° = 90°. Thus, the answer is option D.
Explanation:The subject of this question is Mathematics, specifically it refers to geometry, solving for a variable, and understanding the concept of complementary angles. Let's analyze the options provided.
Two angles are said to be complementary if the sum of their measure is 90 degrees. So, if angle LOM and angle MON are complementary, the sum of m∠LOM and m∠MON should be 90°. Since the measure of m∠LOM is given as (x + 15)° and the measure of m∠MON is given as 48°, the equation that represents this relationship is (x + 15)° + 48° = 90°.
Therefore, option D is the correct choice to solve for x.

Pythagorean theoremLaw of CosinesStep-by-step explanation:
It looks like you have an isosceles trapezoid with one base 12.6 ft and a height of 15 ft.
I find it reasonably convenient to find the length of x using the sine of the 70° angle:
x = (15 ft)/sin(70°)
x ≈ 15.96 ft
That is not what you asked, but this value is sufficiently different from what is marked on your diagram, that I thought it might be helpful.
__
Consider the diagram below. The relation between DE and AE can be written as ...
DE/AE = tan(70°)
AE = DE/tan(70°) = DE·tan(20°)
AE = 15·tan(20°) ≈ 5.459554
Then the length EC is ...
EC = AC - AE
EC = 6.3 - DE·tan(20°) ≈ 0.840446
Now, we can find DC using the Pythagorean theorem:
DC² = DE² + EC²
DC = √(15² +0.840446²) ≈ 15.023527
a ≈ 15.02 ft
_____
You can also make use of the Law of Cosines and the lengths x=AD and AC to find "a". (Do not round intermediate values from calculations.)
DC² = AD² + AC² - 2·AD·AC·cos(A)
a² = x² +6.3² -2·6.3x·cos(70°) ≈ 225.70635
a = √225.70635 ≈ 15.0235 . . . feet
Write the equation of the parabola that has the vertex at point (2,7) and passes through the point (−1,3).
Answers
The equation of the parabola with the vertex at (2,7) and passing through (-1,3) is y = -(4/9)(x - 2)^2 + 7, found by substituting the given points into the vertex form of a parabola's equation.
Explanation:To find the equation of a parabola given its vertex and a point it passes through, we use the vertex form of a parabola's equation, which is y = a(x - h)^2 + k, where (h, k) is the vertex of the parabola.
Given the vertex at (2,7) and a point (-1,3) through which the parabola passes, we substitute these values into the vertex form to find the value of 'a'.
Substituting the vertex, we have:
y = a(x - 2)^2 + 7
Then, substituting the point (-1,3) into the equation, we get:
3 = a(-1 - 2)^2 + 7
Solving for 'a', we get:
3 = a(3)^2 + 7 \n3 = 9a + 7 \n-4 = 9a \na = -4/9
Therefore, the equation of the parabola is:
y = -(4/9)(x - 2)^2 + 7
The equation of the parabola with the vertex at (2,7) and passing through (-1,3) is y = -(4/9)(x - 2)2 + 7, found by substituting the given points into the vertex form of a parabola's equation.
To find the equation of a parabola given its vertex and a point it passes through, we use the vertex form of a parabola's equation, which is y = a(x - h)2 + k, where (h, k) is the vertex of the parabola.
Given the vertex at (2,7) and a point (-1,3) through which the parabola passes, we substitute these values into the vertex form to find the value of 'a'.
Substituting the vertex, we have:
y = a(x - 2)2 + 7Then, substituting the point (-1,3) into the equation, we get:
3 = a(-1 - 2)2 + 7
Solving for 'a', we get:
3 = a(3)2 + 7n3 = 9a + 7n-4 = 9ana = -4/9
Therefore, the equation of the parabolais: y=-(4/9)(x-2)2+7
