Answer:
Step-by-step explanation:
Given that,
y = x + 6 equation 1
3x - 3y = -18. Equation 2
Substitute equation 1 into equation 2
3x-3(x+6) = -18
3x - 3x - 18 = -18
-18 = -18
Therefore, it has no solution. Check attachment for echelon matrix solution
B. y = -2x + 5 equation 1
2x + y = -7. Equation 2
Substitute equation 1 into 2
2x -2x + 5 = -7
5 = -7
Since the equation is not balance, then, it has infinite numbers of solution.
C. y = -4x + 11. Equation 1
6x + y = 11. Equation 2
Substitute equation 1 into 2
6x - 4x + 11 = 11
2x = 11 - 11
2x = 0
x = 0
Also, y = -4x + 11
y = 0 + 11 = 11
Then, this has a unique solution I.e. one solution.
3/5=x/25
Multiply both sides by 25 to get: x = 25(3/5)x = 15
Hope I wasn't too late!
Answer:
-14
Step-by-step explanation:
The like terms in this equation is y^2 and -7y^2 so combining the two the equation becomes:
xy-6y^2
Then we substitute the values in:
5×2-6×2^2 = -14
Answer:
So the correct option is C ) 58 units.
Also If we require Distance then l(AC) = √58 = 7.615 units
Step-by-step explanation:
Let the Points be
point A( x₁ , y₁) ≡ ( -2 , 1)
point C( x₂ , y₂) ≡ (5 , -2)
To Find:
d(AC) = ?
Solution:
By Applying the Pythagorean Theorem to find the distance between points A and C we get
Substituting A( x₁ , y₁) ≡ ( -2 , 1) and C( x₂ , y₂) ≡ (5 , -2) we get
So the correct option is C ) 58 units.
If we require Distance then l(AC) = √58 = 7.615 units
