Answer:
y=mx+b is 32x53 divide by 10 and =8.31=b+423.1/74=mx=647.bd-5634=y add them up and is your answer.
Step-by-step explanation:
R / (r + g) = 1/5 === 5r = r + g === 4r = g
<span>(r + 5) / (r + 5 + g) = 1/3 --- 3r + 15 = r + 5 + g </span>
<span>2r = g - 10 ... 4r = 2g - 20 </span>
<span>g = 2g - 20 </span>
<span>g = 20 .... 4r = g ... r = 5 </span>
<span>20 green and 5 red </span>
Answer:
B: -6+2i
Step-by-step explanation:
- 3i + (-6 - i) = ⇒ open parenthesis
- 3i - 6 - i = ⇒ simplify
- -6 + 2i ⇒ answer in standard form of a+bi
