Answer:
Yes
Step-by-step explanation:
Substitute the x and y values in for x and y to check.
-1 = 7 - 8
-1 = -1
In this instance, (7, -1) is a solution of y = x - 8.
Answer:
a) 24 degrees
b) 50 degrees
Step-by-step explanation:
part a : use sine-1
sine-1 = ![\frac{opposite}{hypotenuse}](https://tex.z-dn.net/?f=%5Cfrac%7Bopposite%7D%7Bhypotenuse%7D)
sine-1 = ![\frac{17}{42}](https://tex.z-dn.net/?f=%5Cfrac%7B17%7D%7B42%7D)
sine-1 = 0.405
missing angle = 23.89
round to the nearest degree = 23.89 = 24
part b : use cosine-1
cos-1 = ![\frac{adjacent}{hypotenuse}](https://tex.z-dn.net/?f=%5Cfrac%7Badjacent%7D%7Bhypotenuse%7D)
cos-1 = ![\frac{16}{25}](https://tex.z-dn.net/?f=%5Cfrac%7B16%7D%7B25%7D)
cos-1 = 0.64
missing angle = 50.208
round to the nearest degree = 50.208 = 50
Step-by-step explanation:
To find the slope, you divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those same 2 points.
Answer:
6y -8
Step-by-step explanation:
8y-2(y+4)
Distribute the 2
8y -2y -8
Combine like terms
6y -8
<span>f(x) = (x^2-16) / (x+3)
f(x) has no horizontal asymptote.
Vertical assymptote is x = -3
Dividing the numerator by the denominator gives x - 3 remainder -7. Therefore, the oblique assymptote is x - 3.

<span>the vertical asymptotes of the function f(x) = (5x + 1) / (x^2 + x - 6) = (5x + 1)/(x - 2)(x + 3) is x = 2 and x = -3.
