Answer: y= -4x/3 - 4/3
Step-by-step explanation:
The equation of the line in the slope-intercept form is y=3x4−32.
The slope of the perpendicular line is negative inverse: m=−43.
So, the equation of the perpendicular line is y=−4x3+a.
To find a, we use the fact that the line should pass through the given point: −4=(−43)⋅(2)+a.
Thus, a=−43.
Therefore, the equation of the line is y=−4x3−43.
Answer: it is a solution set
Step-by-step explanation:
The given system of simultaneous linear equations is expressed as
7x-3y=6 - - - - - - - - - -1
2x+y=11 - - - - - - - - - - - 2
We would eliminate x by multiplying equation 1 by 2 and equation 2 by 7. It becomes
14x - 6y = 12
14x + 7y = 77
Subtracting, it becomes
- 13y = - 65
Dividing the left hand side and the right hand side of the equation by - 13, it becomes
- 13y/13 = - 65/- 13
y = 5
Substituting x = 5 into equation 2, it becomes
2x + 5 = 11
Subtracting 5 from the left hand side and the right hand side of the equation, it becomes
2x + 5 - 5 = 11 - 5
2x = 6
Dividing the left hand side and the right hand side of the equation by 2, it becomes
x = 6/2 = 3
Answer:
x = 7
Step-by-step explanation:
7 = 7
It's given
Answer: No
Step-by-step explanation:
Pythagorean Theorem goes with a right triangle, the formula is a^2+b^2=c^2.
Let's try this out with your values.
(18*18)+(12*12) = 468
If this is true than c^2 is 468
c^2 or (22*22) is 484 is this is not a right triangle.
