Answer:
what is the lesson? abot?
Step-by-step explanation:
Cosine of angle A is also x
This is because the sine is opposite over hypotenuse and cosine is adjacent over hypotenuse so both sine and cosine in this example are asking for the same side over the hypotenuse which means cosine of angle A will be the same as sine of angle B
I believe this is correct but I may be wrong, let me know what it ends up being!
Answer:
y = 6x + 9
Step-by-step explanation:
Δy =-3-3 = -6
Δx =-2-(-1) = -1
Slope = Δy/Δx = 6
Point-slope equation for line of slope 6 that passes through (-1,3):
y-3 = 6(x+1)
Rearrange to solve for y:
y = 6x + 9
