The use of sine and cosine could give you the angle measuments of the triangle, along with the use of tangent. Not only could it give you the angle measurements but the lengths of the sides.
<span>To determine whether (−1,4) is a solution to the equation 3x+8y=29, substitute ...-1... for x and ...4... and for y.
In a pair of values like (-1, 4), the first coordinate, or entry, occupied by -1 always represents x.
Similarly, the second coordinate occupied by 4 represents y.
Answer: </span>substitute ...-1... for x and ...4... and for y.
Answer:
21-7x
Step-by-step explanation: gather like terms
25-4=21 -9x+2x=-7x
23, it has to be less than 24 since 25, 26, and 30 are greater than 24.
Answer:
y = 8x + 4(6)
y = 8x + 24
Step-by-step explanation:
8 friends bought tickets to a hockey game at $x
4 of them also bought a guide book at $6
If y = total cost
8 people bought tickets and 4 bought guides.
Then simplify by multiplying 4 and 6.
