Answer:
27 stuffed bears
Step-by-step explanation:
Erin: 55 Su: 15
Erin: 55-7=48 ( 7 will be kept for herself)
Erin and her sisters: 48/4= 12
Each sister besides Erin and Su have 12
Su: 15+12=27
Thus, Su will have 27 stuffed bears
Step-by-step explanation:
The slope of the tangent line of a function f(x) is the derivative, f'(x).
Here, we can use exponent rule to find the derivatives:
If y = xⁿ, then y' = nxⁿ⁻¹.
7. g(x) = x²
g'(x) = 2x
g'(2) = 4
8. g(x) = x² − 4x
g'(x) = 2x − 4
g'(1) = -2
9. g(x) = 5/(x + 3)
g(x) = 5 (x + 3)⁻¹
g'(x) = -5 (x + 3)⁻²
g'(-2) = -5
Answer:
Step-by-step explanation:
-4b + 2w + (-4b) + 8w
Write the like terms together
= (-4b) + (-4b) + 2w + 8w {add the like terms}
= -8b + 10w
