Step-by-step explanation:
first your going to break down your total then since you have nine balls of yarn you going to take out the 9.45
-3(y+2)^2-5+6y
-3(y^2+4y+4)-5+6y
-3y^2-12y-12-5+6y
-3y^2-6y-17
Answer:
is equivalent to 
Step-by-step explanation:
Using exponent rules:
Given the expression:
⇒
Apply the exponent rule, we have;
Therefore, the given expression is equivalent to
So here is the answer to the given question above. Analyzing the given figure, we can see that at 0 miles, the cost is 25. Between 0 and 40 miles, the cost rises by 10. Therefore, the function that would represent this situation would be this: <span>f(x) = (10/40)x+25
</span><span> f(x) = 1/4 *x+ 25
f(x) = 0.25x + 25
Hope this is the answer that you area looking for. </span>
