Answer:
1/21
Step-by-step explanation:
2x + y ≤ 10
<span>y ≤ - 2x + 10 → you can see the line in red </span>
<span>As the sign is ≤, you keep only the part below the red line, included the red line </span>
<span>2x - 4y < 8 </span>
<span>- 4y < - 2x + 8 </span>
<span>y > (- 2x + 8)/- 4 </span>
<span>y > - (1/2)x - 2 → you can see the line in blue </span>
<span>As the sign is >, you keep only the part above the blue line
</span><span>A, C, D, K</span>
Answer:
3/5
Step-by-step explanation:
Using SOHCAHTOA, we know that cos Ф = 
So, we know that cos Ф = 
or, using the hint, 3/5
1/3x - 2/3 = -18
1/3x = -18 + 2/3
x = -54 + 2
x = -52 answer
