Y=4x+1
Let y=0
0=4x+1
4x=-1
x=-1/4
Let x=0
Y=4*0+1
Y=0+1
Y=1
Therefore, the ordered pair is (-1/4, 1)
Maybe you should work on starting you're sentences.

(a) For dx/dt=6, dy/dt = 2·6 = 12
(b) For dy/dt=2, 2 = 2·dx/dt ⇒ dx/dt = 1

The value of x is irrelevant for this question.
=====
If your function is 2^x +1 or 2^(x +1), it needs to be written as such. The answer above applies to the function given.
Answer:
2. tan 280°
3. -tan 80°
Step-by-step explanation:
Your calculator can help you figure this out.
__
The tangent function is periodic with a period of 180°, so tan(100°) will be equal to tan(100°+k·180°) for any integer k. Answer choices include k values of ±1, so two of them are correct:
- tan(100°) = tan(100° -180°) = tan(-80°)
- tan(100°) = tan(100° +180°) = tan(280°)
It is too blurry to read please correct me if this is wrong question
a =17,a =3 is that what the question says?
