Y = mx + c, where m is your gradient and c is your y intercept.
If the line is perpendicular to the line y = 3x - 5, the line's gradient = -(1/3) as when it comes to perpendicular bisector, m1/m2 = -1
y = -(1/3)x + C
To find C sub in x=2 and y=2 as it goes through (2,2)
2 = -(1/3)2 + C
2 = -(2/3) + C
2 + 2/3 = C
C = 8/3
There your equation of a line is
y = -(1/3)x + 8/3
Answer:
x = -1/2
Step-by-step explanation:
(x - 4) * 2 = -9
Divide both sides by 2:
x - 4 = - 9 / 2
Add 4 to both sides:
x = - 1 / 2.
Assume that x² + kx + 18 if factorable.
The factors of 18 are
(1 x 18); (2 x 9); (3 x 6).
If we use (1, 18) as factors, then
(x - 1)(x - 18) = x² - 19x + 18 => k= -19
or
(x + 1)(x + 18) = x² + 19x + 18 => k = 19
If we use (2,9) as factors, then
(x - 2)(x - 9) = x² - 11x + 18 => k = - 11
or
(x + 2)(x + 9) = x² + 11x + 18 => k = 11
If we use (3, 6) as factors, then
(x - 3)(x - 6) = x² - 9x + 18 => k = - 9
or
(x + 3)(x + 6) = x² + 9x + 18 => x = 9
Answer:
The possible values of k are -9,+9, -11, +11, -19, +19.
Answer:
x=44
Step-by-step explanation:
since it's a 90 degree triangle
2x+2=90
2x=88
x=44
