Answer:
d=2√13
Step-by-step explanation:
B(1,4) T(4,6) what is BD
find BT
d=√(x2-x1)²+(y2-y1)²
d=√(4-1)²+(6-4)²
d=√3²+2²
d=√9+4
d=√13 this is haf the distance
BD=2d=2√13
Answer: k = -1/3
Step-by-Step Explanation:
=> 3x - 2ky + 4 = 0
Value of ‘x’ = -2
Value of ‘y’ = 3
Substitute values of ‘x’ and ‘y’ :-
=> 3x - 2ky + 4 = 0
= 3(-2) - 2k(3) + 4 = 0
= -6 - 6k + 4 = 0
= -6k = 6 - 4
= -6k = 2
= k = 2/-6
=> k = -2/6 = -1/3
Therefore, k = -1/3
The number is: " -3 " .

Let "x" be the "unknown number" for which we are to solve.
8x − (-54/9) = -18 ; Solve for "x" ;
→ 8x − (-6) = - 18 ;
→ 8x + 6 = - 18 ;
Subtract "6" from each side of the equation:
→ 8x + 6 − 6 = - 18 <span>− 6 ;
to get: 8x = -24 ;
Divide EACH SIDE of the equation by "8" ; to isolate "x" on one side of the equation ; & to solve for "x" ;
8x / 8 = -24 / 8 ;
to get: x = -3 .

Answer:
a= 9
Step-by-step explanation:
If you are using the forumla a+b=c
a+48=57
57-48=9
a=9
9=48=58
Answer:
C
Step-by-step explanation:
f(x) - g(x)
= - x + 4 - (6x + 3)
= - x + 4 - 6x - 3 ← collect like terms
= - 7x + 1 → C
