Answer:
a. f(-2) = -6
b. f(0) = 6
c. f(2) = 10
Step-by-step explanation:
The function is given as:
f(x) = 5x + 4 if x < 0
f(x) = 2x + 6 if x ≥ 0
(a) f(-2)
x < 0:
=> f(-2) = 5(-2) + 4
f(-2) = -10 + 4
f(-2) = -6
(b) f(0)
x ≥ 0:
=> f(0) = 2(0) + 6
f(0) = 6
(c) f(2)
x ≥ 0:
=> f(2) = 2(2) + 6
f(2) = 4 + 6
f(2) = 10
Answer:
6,537 grams
Step-by-step explanation:
7kilograms=7000 grams
This becomes...........
[(y+7)/7y] x [(14y-5)/(3y^2+21y)]= [(y+7)/7y] x [(14y-5)/3y(y+7)]= [1/7y] x [(14y-5)/3y]= [(14y-5)/21y]
