Answer:
uhhh... why dont you check my work lol
Step-by-step explanation:
y = -15/18x + b
-1 = -15/18 (6) + b
-1 = 5 + b
-6 = b
check your work:
14 = -15/18(-12) - 6
14 = 10 - 6
14 = 4
Answer:
I'm confused
Step-by-step explanation:
maybe you should help me....
Answer:
arc length d = ∫ √(1 + (dy/dx)²) dx
y = 228 - x²/57
dy/dx = -2x / 57
(dy/dx)² = (2x/57)²
Upper limit for integration:
y = 0 = 228 - x²/57
yields x = 114
d = ∫ √(1 + (2x/57)²) dx for 0 ≤ x ≤ 114 = 264.9 m

Answer:
Angela is 13 years old and Angela's aunt is 41 years old.
Step-by-step explanation:
With the information provided you know that Angela's aunt is two more than three times her age, which could be expressed as:
x=3y+2, where:
x is Angela's aunt age
y is Angela's age
Also, you know that the total of their ages is 54, which is:
x+y=54
Now, you can replace x=3y+2 in x+y=54 and solve for y:
3y+2+y=54
4y=54-2
4y=52
y=52/4
y=13
Finally, you can replace the value of y in x=3y+2 to find x:
x=3(13)+2
x=39+2
x=41
According to this, the answer is that Angela is 13 years old and Angela's aunt is 41 years old.
