Your answer is no solutions.
Multiply the first equation by - 2.
- 2(3x - 2y = 6)
- 6x + 4y = -12
Combine the like terms of this equivalent equation and the original second equation.
- 6x + 4y = -12
6x - 4y = 14
Everything on the left side of the equal sign cancels out leaving you with:
0 ≠ 2
Because this statement is not true, it means there are no solutions to this system of equations.
Answer:
prime numbers
Step-by-step explanation:
not composite since,example, 2 is prime
not even since,example, 19 is odd
not odd since,example, 2 is even
Bill moves at 45 feet per minute and Greg 75 per minute and starts with a constant of 20 feet from them.
Let X be the number of minutes
Bill*Minutes +Greg*Minutes +20 = total distnce between
45x + 75x +20 = d
Plug in 2.5 for both values of x
45(2.5) + 75(2.5) + 20 =d
Multiply values by 2.5
112.5 + 165 + 20 = d
add together
Distance = 297.5 feet apart
Answer:
0
Step-by-step explanation:
It is been considered that Discriminant is calculated by the following formula:
D = b*b - 4 * a * c
In order to simplify the calculations we can divide all the numbers by 2 and we will have the same quadratic equation:
-x^2 -4x+4=0
and as usual quadratic equation is presented as the following:
ax^2 - bx + c = 0
so in our case a = -1; b = -4; c = 4;
Then D = -4*4 -4*(-1) * 4 = -16+16 = 0
I am not quite understanding the following phrase:
"and what does it value mean about the number about the number"
but if the question was in regards of the following number '-2x^2' so number ^2 is actually the value of power so 'x' is multiplied on it is own and this equation basically means the following:
-2x^2 = -2 * (x) * (x)
The correct answer is C. Randomizing the groups and calculating the means and difference of the means.
