Answer:
5. A.
6. F
Step-by-step explanation:
5. Perpendicular lines have slopes that are negative reciprocals of one another, so slope is 3
y = 3x + b
using coordinates (-6,3)
3 = 3(-6) + b
b = 21
y = 3x + 21
6. I think F is the right answer
Hello.
17. ( 3 + 5 ) · 8 = 64
18. 4 · ( 6 - 2 ) + 7 = 23
19. 10 ÷ ( 3 + 2 ) · 4 = 8
20. ( 3 + 6 ) · 2 = 18
---------------------------------
Step-by-step explanation:
We can prove the statement is false by proof of contradiction:
We know that cos0° = 1 and cos90° = 0.
Let A = 0° and B = 90°.
Left-Hand Side:
cos(A + B) = cos(0° + 90°) = cos90° = 0.
Right-Hand Side:
cos(A) + cos(B) = cos(0°) + cos(90°)
= 1 + 0 = 1.
Since LHS =/= RHS, by proof of contradiction,
the statement is false.
Answer:
k = -9
Step-by-step explanation:
subtract 2k from both sides
_5k+8= -37
subtract 8
_5k = -45
divide by 5
_k = -9
3*(18-13)
3* 5
15
The answer is 15
