So if she bought 20 share of stock for $175 that means that she paid $8.75 for each stock so if she made $25 you add then you divide
175÷20 = $8.75
175+$25=$200 she sold them for
$200 ÷ 20= $10
Answer:
B
Step-by-step explanation:
Plug in:
y = 2
x = 0
2 x 0 = 0 - 1 = -1
2 is greater than / equal to -1
Answer:
20
Step-by-step explanation:
f(x)= 3x²-2x+4
f(-2)=3×(-2)²-2(-2)+4
=3×4)+4+4
=12+4+4
=20
Answer:
y=4(1/2)^x
Step-by-step explanation:
Start with x=0, you know any number to the power of 0 is one. Since y=4, when x=0, you know the coefficient out front must be 4 b/c 4*1=4.
Next, look at x=1, which is equals 2. 1/2^1 = 1/2. Multiply by 4 to get 2. That means that b must equal 1/2. You can check this by looking at x=2. At x=2, y=1. (1/2)^2=1/4. 1/4(4)=1, making 1/2 the b value.
