Answer:
c < 32/27
Step-by-step explanation:
−7−5(−4c+4)<−7c+8−3
Step 1: Simplify both sides of the inequality.
20c−27<−7c+5
Step 2: Add 7c to both sides.
20c−27+7c<−7c+5+7c
27c−27<5
Step 3: Add 27 to both sides.
27c−27+27<5+27
27c<32
Step 4: Divide both sides by 27.
27c/27 < 32/27
c < 32/27

Step-by-step explanation:
Function notation is a system of representing functions.
Rotation 90° translates (x, y) to (-y, x). Thus (3, 2) gets translated to (-2, 3). Your green box gets filled with -2.
<span>A= 5 i â’ 3 J and B = â’i â’ 6 j
A+ B
=5 i â’ 3 j â’i â’ 6 j = 4 i - 9 j ---answer
A - B
= 5 i â’ 3 j + i + 6 j = 6 i + 3j ---answer
|A+B|
= sq root [ 16 + 81] = 9.848 ---answer
|A - B|
= sq root [ 36 + 9] = 6.708 ---answer
directions of A+ B
= tan (-1) -9 /4 = - 66 deg --answer
direction of A- B
= tan (-1) 3 /6 = 26.56 deg --answer</span>
