We can write the equation in point-form in this case. The equation should be:
y-y1 = m(x-x1)
y and x can be any point in the line, so we leave them just like that in the equation, we don’t have to add any numbers to them. m is the slope of the line, and (x1, y1) is the given point in the line, which is (-1, 1) in this case.
Now, just substitute the number in,
y - 1 = -2 [x - (-1)]
y - 1 = -2 (x+1)
y - 1 = -2x - 2
2x + y + 1 = 0
So, 2x + y + 1 = 0 is your answer.
Answer:
3.821in
Step-by-step explanation:
C=2pi×r
24=2×3.14×r

r=3.821inches
Answer:
156.37°
Step-by-step explanation:
We solve this above question, using Cosine rule which is given as:
Cos C = a² + b² - c²/2ab
Let the Angle be represented as: x
Cos x = 310² + 200² - 150²/2 × 310 × 200
x = arc cos [ 310² + 200² - 150²/2 × 310 × 200]
x = 23.63°
The angle, in degrees, that he must turn through to head straight for Island B is given as:
180° - 23.63°
= 156.37°
Answer:
m=-3
Step-by-step explanation:
(1.06)60 is greater than 60, because 1.06 multiplied by 60 is 63.6, and 63.6 is greater than 60. Hope this helps fam
