Answer:
f(4) = 6
Step-by-step explanation:
f(x) = 3x - 6
f(4) = 3(4) - 6
f(4) = 12 - 6
f(4) = 6
Answer: Option (B) is correct.
<em>Given:</em>
<em>P = $6000</em>
<em>r = 6%</em>
<em>t = 6 years and 7 months = 79 months</em>
∵ It is compounded semi-annually
∴ 

I = 8854.72 - 6000
<em>I = 2854.72</em>
The first one. The sum of all angles on a triangle is always equal to 180
Answer:
<h2>y= 50x+ 225 \</h2><h2 />
Step-by-step explanation:
Given that
the number of colors on the shirts(x), and
the total cost of the order(y).
since the number of colors is given as x
the total cost y can be represented as
y= 50x+ 75(3)
y= 50x+ 225
hence the total cost of 75 T-shirts is given by the model
<h2>y= 50x+ 225 </h2>
