C
(1, 3) is 5 units to the right of (-4, 3)
Answer:
The Correct Answer are
- The ordered pair (2, 3) is not a solution to the system of linear equations.
- When (2, 3) is substituted into the first equation, the equation is true.
- When (2, 3) is substituted into the second equation, the equation is false.
Step-by-step explanation:
The Correct Answer are
- When (2, 3) is substituted into the first equation, the equation is true.
3x + 4y = 18 equation ( 1 )
3×2 + 4×3 = 18
6 + 12 = 18
18 = 18
- When (2, 3) is substituted into the second equation, the equation is false.
2x – 2y = 2
2×2 - 2×3= 4 - 6 = -2≠2
- The ordered pair (2, 3) is not a solution to the system of linear equations.
Solution means if we (2, 3) Substitute in both the Equation it Must Satisfy
But in Equation 1 it Satisfy
and in Equation 2 Not satisfy
Therefore It is NOT a solution to the system.
Answer:
Radius: 4.2cm
Diameter: 8.4cm
Step-by-step explanation:
Radius is half of the diameter.
In order to find the diameter, you would have to multiply the radius by 2.
In order to find the radius, you would have to divide the diameter by 2.
Answer:
Each goal gives 5 points and a penalty costs 7 points.
Step-by-step explanation:
Let a penalty cost = x points
And a goal gives = y points
Ben makes 7 goals and 2 penalties ending the game with 21 points,
7y - 2x = 21 --------(1)
Alyssa makes 10 goals and 8 penalties ending the game with (-6) points,
10y - 8x = -6
5y - 4x = -3 --------(2)
Equation (1) multiplied by 2, then subtracted from equation (2),
(5y - 4x) - 2(7y - 2x) = -3 - 2(21)
5y - 4x - 14y + 4x = -3 - 42
-9y = -45
y = 5
From equation (1)
7(5) - 2x = 21
35 - 2x = 21
2x = 35 - 21
2x = 14
x = 7
Therefore, each goal gives 5 points and a penalty costs 7 points.
10000 times the value of the other one
