Analyze each step to identify if Andy made an error
Andy wrote the equation of a line that has a slope of
and passes through the point (3,-2) in function notation.
Step 1: y-(-2) = (x - 3)
Step 2: y + 2 = x-
Step 3: y + 2 + 2 = x -+ 2
Step 4: y = x-
Step 5: f(x) = x -
Yes, he made an error in Step 1. He switched the x
and y values
Yes, he made an error in Step 2. He did not
distribute 3 properly
Yes, he made an error in Step 3. He should have
subtracted 2 from both sides.
No, his work is correct.

angle addition postulate

2x=56

step-by-step explanation:

there is no graph so i cant sorry

step-by-step explanation:

7.9m and 4.3°

step-by-step explanation:

let east be +x and north be +y, x = distance * cos θ, y = distance * sin θ  

for 3.5 south, y = -3.5  

for 8.2, x = 8.2 * cos 30 and y = 8.2 * sin 30  

for 15 west, x = -15  

total x = 8.2 * cos 30 – 15 ≈ -7.9  

total y = -3.5 + 8.2 * sin 30 = 0.6  

magnitude = [(8.2 * cos 30 – 15)^2 + 0.6^2)]^0.5  

the magnitude is approximately 7.9 m  

tan θ = y/x = 0.6/-7.9  

the angle is approximately 4.3˚ north of west

y= -2x+4, have a great day
