Answer:
y = 3x - 1
Step-by-step explanation:
Let's start with the two points.
y = mx + b
-19 = -6m + b
5 = 2m + b
Subtract the first from the second.
24 = 8m
m = 3
5 = 2*3 + b
b = -1
Answer:
24
Step-by-step explanation:
Four total places someone can come - 1st, 2nd, 3rd or 4th. Anyone can come 1st - 4 people
Now only the remaining 3 can come second - 3 people
Next, only the remaining 2 people can come third - 2 people
Finally, one person comes last - 1 person
4 x 3 x 2 x 1 = 24
Multiply 5 by 5 to get 25

Answer:
A 9 ⋅ 1019
B 7.8 ⋅ 106
C 1.45 ⋅ 10−7
D 0.33 ⋅ 10−15
Step-by-step explanation:
A 9 ⋅ 1019
B 7.8 ⋅ 106
C 1.45 ⋅ 10−7
D 0.33 ⋅ 10−15
The derivative, f'(x) = 6x^2+1, is never negative, so f(x) is monotonic, hence invertible.
f'(-2) = 6(-2)²+1 = 25
If point (-2, -26) is on the graph of function f(x), and the slope is 25 there, then (-26, -2) is on the graph of f⁻¹(x), and the slope is 1/25 there. The equation of the tangent line throught that point can be written in point-slope form as
... y +2 = (1/25)(x +26)
