Y - y1 = m(x - x1)
slope(m) = -56
(8,-4)...x1 = 8 and y1 = -4
now we sub...pay close attention to ur signs
y - (-4) = -56(x - 8)....not finished yet
y + 4 = -56(x - 8) <===
Answer:
2.9 mi
Step-by-step explanation:
The time difference t between 12.30pm and 3.30pm is 3h.
Let the distance to Marat's house be s.
The equation to calculate velocity v is given by:
v = distance / time.
Now you can write an equation for the time difference t and use the two velocities and the 90 min(= 1.5h) she stays:
3 = s/12 + 1.5 + s/2.3
Solve this equation for s:
(1/12 + 10/23)* s = 1.5
s = 2.9
Answer:
28
Step-by-step explanation:
1) subtract 12 from both sides
2) divide by negative 1
Answer:
34
Step-by-step explanation:
15 mins is 1/4 od an hour so mulitply 8 1/2 (8.5) x 4
Step-by-step explanation: the answer for this question should be 81.64 because to find the circumference you need to know the circumference formulas which is C=TT times d or C= 2 times TT times r.
C= 3.14 times 26 C= 2 times 3.14 times 13
C= 81.64
C= 81.64
so the answer is 81.64 for the circle's circumference so hopefully that is the correct answer and have a great day
