Answer:
can u help me with my history homework and ill help u with urs
Step-by-step explanation:
1. Is 8 seconds
2. I think is 15 quartz sorry if I’m wrong
<span>P(9,12): For all intents and purposes, the hypotenuse is "r", the opposite side is "y", and the adjacent side is "x".
x = 9 (from the P(9,12))
y = 12 (also from the point)
Using the Pythagorean Theorem, you find out that r = 15.
Therefore, since cos θ = x/r
cos θ = 9/15 or 3/5
Answer: 3/5</span>
Y = mx + b
y = 4x + b
Plug in point
7 = 4(2) + b, b = -1
Equation: y = 4x - 1
