The slope is y=1/2x + 2 or y= 0.5x+2
Answer:
Inverse of cosine (StartFraction StartRoot 3 EndRoot Over 2 EndFraction)
Step-by-step explanation:
According to trigonometry identity;
Cos 30° = √3/2
To get the expression equivalent to 30°, we will take the inverse of both sides as shown;
Cos^-1(cos 30°) = cos^-1(√3/2)
The arccos will cancel out the cos on the left hand side of the equation to have;
30° = cos^-1(√3/2)
Hence 30° is equivalent to inverse of cosine of √3/2 or Inverse of cosine (StartFraction StartRoot 3 EndRoot Over 2 EndFraction)
Answer:
Step-by-step explanation:
a + b = 3b
a = 3b - b
a = 2b
a/b = 2/1
a:b = 2:1
In order to find the temperature, you have to add -4 + 16. this would be C because negatives subtract. Hope you found this helpful!
