Answer:
Step-by-step explanation:
Several trig identities are involved in the proof of this. This is the order in which they are used.
- cos(2x) = cos²(x) -sin²(x)
- cos²(x) +sin²(x) = 1
- cos(x) = 1/sec(x)
<h3>Proof</h3>
Starting with the left side, we can transform it into the right side.
(10^2 +10^2)^.5 = 10*(sqrt2)
Answer:
y=3x-5
Step-by-step explanation:
slope intercept form: y=mx+b
-2y=-6x+10
2y=6x-10
y=3x-5
Don’t know if there’s much of an equation for it, but I guess the best way to write it out is 10 + x = -18. Then, you would subtract the 10 from both sides in order to isolate the x. So then you’re left with x = -28. So -28 is your answer.
5 units. The only variable changing is x so it's just 5 units up from the second coordinate
