Answer:
6
Step-by-step explanation:
15/2.5=6
Time=number of cuts times time it takes to make each cut
to cut something into 2 pieces, you need 1 cut
to cut into 3 pieces you need 2 cuts
therefor, to cut something into n pieces, it takes n-1 cuts
so 8piece is 8-1=7 cuts
time=number of cust times time per cut
time=7 times 5 minutes
times=35 minutes
Okay, so let's break it down step-by-step:
1) distribute the 2 inside the parenthesis (2*x and 2*5) it gives you 2x-10
2)So now you're equation is Y-3=2x-10. You want Y by itself if you want it in Y-intercept form. So add three on each side. 3 cancels out on the right.
Y-3=2x-10
+3 +3
-----------------
Y= 2x+13
3) And there you go, Y=2x+3 is the answer
Answer:
f(1) = 2
Step-by-step explanation:
To find f(1), substitute x = 1 into f(x), that is
f(1) = 1² + 3(1) - 2 = 1 + 3 - 2 = 2
