Answer:
If a consistent system has an infinite number of solutions, it is dependent . When you graph the equations, both equations represent the same line. If a system has no solution, it is said to be inconsistent . The graphs of the lines do not intersect, so the graphs are parallel and there is no solution.
Step-by-step explanation:
Hope this helps - Good luck ^w
we can conclude that the system of linear equations has no solution when the graphs of equations are parallel.
What is a linear system of equations?A system of linear equations consists of two or more equations made up of two or more variables such that all equations in the system are considered simultaneously. The solution to a system of linear equations in two variables is any ordered pair that satisfies each equation independently.
The collection of one or more linear equations, such that each of those equations have same set of variables, are known as system of linear variables.
If a consistent system has an infinite number of solutions, it is dependent. When we graph the equations, both equations represent the same line.If a system has no solution, it is said to be inconsistent .

What is an equation in point-slope form of the line that passes through (-7,1) and (-3, 9)
Step-by-step explanation:
let eqn be y - y1 = m(x - x1)
m = (9 - 1)/(-3 - (-7))
m = 2
sub (-7, 1):
y - 1 = 2(x + 7)
therefore, the equation is y - 1 = 2(x + 7)

What is the solution of the equation 8(g - 18) =160
Answer:
g = 38Step-by-step explanation:
8(g - 18) = 160
8g - 144 = 160
g = (160 + 144) / 8
g = 38
Answer:
g = 38
Step-by-step explanation:
8(g - 18) = 160
8g - 144 = 160
8g = 204
g = 38

Which of the following best shows two elements combining to form a compound!? Explain...
Chemistry.
Answer:
C because elements are form by atoms and when we study about atom we draw atom like circle
so, that's why I think C is correct
Step-by-step explanation:
Option C best shows two elements combining to form a compound.
What is molecular structure?The term "molecular structure" refers to the structure of a molecule that merely consists of the arrangement of its atoms.
A chemical compound is a material made of several similar molecules that are linked together by chemical bonds and are made up of atoms from various elements.
Chemical compounds cannot be created when two atoms of the same element are bound together since this would need the presence of two distinct elements.
In diagram C it is obtained that atoms are combined to form the compound.
The finest example of two components combining to make a compound is in Option C.
Hence, option C is correct.

A 40 kg-skier is standing at the top of a 12-meter high slope. What is her potential energy? PE = m x g x h (g = 10m/s2) A. 6000J B. 48J C. 4800J D. 400J
Answer:
The correct option is;
C. 4800 J
Step-by-step explanation:
The given parameters are;
The mass of the skier = 40 kg
The height of the slope = 12 meter
The acceleration due to gravity, g = 10 m/s²
The potential energy, PE, is given by the formula PE = Mass, m × Acceleration due to gravity, g × Height, h
Substituting the values, gives
The potential energy, PE = 40 kg × 10 m/s² × 12 m = 4800 kg·m²/s² = 4800 J
The potential energy, PE = 4800 J
Find the center and radius of the circle given by this equation: x^2 - 10x + y^2 + 6y - 30 = 0
Answer:
center=(5,-3)
radius = 2 unit
Step-by-step explanation:
Center with the equation x² - 10x + y² + 6y - 30 = 0 is (5, -3) and the radius is 8 units.
Circle with the given center and radius: Equation of a circle with the center (h, k) and radius 'r' is given by,
(x - h)² + (y - k)² = r²
Here, Center of the circle → (h, k)
Radius of the circle → r units
Given equation of the circle in the question is,
x² - 10x + y² + 6y - 30 = 0
Convert this equation to the standard equation of the circle.
x² - 2(5x) + y² + 2(3y) - 30 = 0
[x² - 2(5y) + 5²] - 5² + [y² + 2(3y) + 3²] - 3² = 30
(x - 5)² - 25 + (y + 3)² - 9 = 30
(x- 5)² + (y + 3)² = 64
(x- 5)² + (y + 3)² = 8²
Therefore, center of the circle is (5, -3) and radius of the circle is 8 units.

An NBA Basketball court is a rectangle that is 94 feet long and 50 feet wide. What is the area of the court? What is the perimeter of the court?
Area= Sq.feet
Perimeter= Feet
Answer:Area = 4700 feet squared
Perimeter= 288 feet
Step-by-step explanation:
Length = 94 feet
Width = 50 feet
Area = Length × Width
= 94 feet × 50 feet
= 4700 feet squared
Perimeter = 2(Length + Width)
= 2(94 feet + 50 feet)
= 2(144 feet)
= 288 feet

How much more wheat was gathered from the second feild than from the first Search instead for The area of one feild is 16 acers and the area of the second felid is 1 1/4 times bigger. A barn of wheat on the first feild makes up 37 1/2 thousands of pounds per acre,and on the second1 2/15 times as much per acer. How much more wheat was gathered from the second feild than from the first
Answer:
250 pounds
Step-by-step explanation:
Since the area of the first field is 16 acres and that of the second field is 1¹/₄ times that of the first field, the are of the second field is thus 16 × 1¹/₄ acres = 16 × 5/4 = 4 × 5 = 20 acres.
Also, A barn of wheat on the first field makes up 37 ¹/₂ thousands of pounds per acre, and on the second 1 ²/₁₅ times as much per acer. So, the amount of wheat per acre of the second field is thus 37 ¹/₂ × 1 ²/₁₅ thousand pounds per acre = 75/2 × 17/15 = 5/2 × 17 = 85/2 = 42 ¹/₂ thousand pounds per acre.
The amount of wheat gathered on the first field is thus 16 acres × 37 ¹/₂ thousands of pounds per acre = 16 × 75/2 = 8 × 75 = 600 pounds
The amount of wheat gathered on the first field is thus 20 acres × 42 ¹/₂ thousands of pounds per acre = 20 × 85/2 = 10 × 85 = 850 pounds
So, the amount of wheat gathered on the second field more than the first is thus 850 pounds - 600 pounds = 250 pounds.

Answer:
58 °F , 20 °F , 11 °F , 2 °F , -2 °F , -5 °F.
Step-by-step explanation:
The biggest positive numbers go first including, 58, 20, and 11.
From there it may get confusing.
2 > -2 this is because 2 is a positive and -2 is a negative. Negative numbers are numbers that are behind zero. Whereas positive numbers are in front of zero.
-2 > -5 normally 5 would be greater than 2. However, negative numbers are backwards. Picture a number line, where positive numbers are going forward...negative numbers are going backwards.

make r the subject of v=4/3 pie r^3 need some help guys
Answer:
r = [tex]\sqrt[3]{\frac{3v}{4\pi } }[/tex]
Step-by-step explanation:
Given
v = [tex]\frac{4}{3}[/tex] πr³ ( multiply both sides by 3 to clear the fraction )
3v = 4πr³ ( isolate r³ by dividing both sides by 4π )
[tex]\frac{3v}{4\pi }[/tex] = r³ ( take the cube root of both sides )
[tex]\sqrt[3]{\frac{3v}{4\pi } }[/tex] = r
