Answer: 31 - 3n
Step-by-step explanation:
step one:
25 - 28 = -3
22 - 25 = -3
19 - 22 = -3
d = -3
Step two:
An = a1 + (n-1) d
= 28 + (n-1) -3
= 28 - 3n + 3
= 31 - 3n
a1= 28 d = 3
Answer:
87°
Step-by-step explanation:
if an angle is complementary that means that equals 90°.
and we know one part of the angles, so then we take 90° - 3° and we get 87°.
Answer: 40
Step-by-step explanation:
Step-by-step explanation:
step 1. slope intercept form: y = mx + b
step 2. m (slope) = (4 - 5)/(3 - 0) = -1/3.
step 3. Pick one of the points: (0, 5).
step 4. b is 5, the y intercept.
step 5. y = (-1/3)x + 5.
