Answer:
Improper fraction (-81t/ 4s)
Mixed number (-20 1/4) (t/s)
Step-by-step explanation:
Multiply the numerators
9(9t) = 81t
Multiply the denominators
4s* (-1) = -4s
Put the numerator over the denominator
81t / -4s
If they want the answer as an improper fraction -81t/4s
If they want a mixed number
81/4 = 20 with 1 left over
20 1/4
Then multiply by (-t/w)
(-20 1/4) (t/s)
The y-intercept is 5
B/c when you solve the equation for y you get
y=5/2x+5
So replace

Good job on writing all of them down! :) I hope this helps
The angle between the two tangents drawn from an external point to a circle and the angle subtended by the line segment joining the points of the contact at the Centre are supplymentary,
So,
15.) let the unknown angle be x
=》x + 55° = 180°
=》x = 180° - 55°
=》
16. let the unknown angle be n
=》n + 80° = 180°
=》n = 180° - 80°
=》
