Answer:
k = 3.75
Step-by-step explanation:
Note the equal sign, what you do to one side, you do to the other. Isolate the variable, k. Divide -1.2 from both sides:
(-4.5)/(-1.2) = (-1.2k)/-1.2
-4.5/-1.2 = k
k = -4.5/-1.2
k = 3.75
3.75 is your answer for k.

Answer:
65º
Step-by-step explanation:
- The angle of a straight line is 180º, so ∠ABD=180º and ∠ABC=(180-6x)º
- The sum of the interior angles of a triangle is 180, so (x+40)º+(3x+10)º+(180-6x)º=180
- We can solve from there, x+40+3x+10+180-6x=180
- Combine like terms, -2x+230=180
- Subtract 230, -2x=-50
- Divide by -2, x=25
- m∠CAB=(x+40)º=(25+40)º=65º
- m∠ABC=(180-6x)º=(180-150)º=30º
- m∠BCA=(3x+10)º=(75+10)º=85º
Answer:
- 1/2
Step-by-step explanation:
(0,0) (2,-1)
m = difference of y/difference of x = (-1 - 0) / (2 - 0) = - 1/2
y = - 1/2 x
