Answer:
f(3) = 2
Step-by-step explanation:
To evaluate f(3), substitute x = 3 into f(x), that is
f(3) = - 2(3) + 8 = - 6 + 8 = 2
15x+25y=1875
Let
y=95-x
15x+25 (95-x)=1875
Solve for x
15x+2375-25x=1875
15x-25x=1875-2375
-10x=-500
X=500/10
X=50 the number of $15 items
Y=95-50=45 the number of $25 items
Answer:
y = 1/3
Step-by-step explanation:
(3y-1)² = 0
First is square root on both sides.
√(3y-1)² = √0
3y -1 = 0
3y = 1
y = 1/3
300 + 110 equals the variable x.
