Answer:
77
Step-by-step explanation:
Plug in:
F(4) = (4)3 + 2(4)2 + 1
F(4) = 12 + (8)^2 + 1
F(4) = 12 + 64 + 1
F(4) = 77
(assuming 2x2 = 2x squared)
Given that l<span>ast week christi spent 2 3/4 hours playing piano this week she spent 3 2/4 hours playing the piano, the extra time spent on piano this week will be:
3 2/4-2 3/4
Converting the above into proper fraction we get:
14/4-11/4
=(14-11)/4
=3/4
Thus she spent and extra 3/4 hours=45 minutes this week</span>
So since there are 2 placeholders, the answer are many, but we can make into slope intercept form to make it easier to solve (slope intercept form is y=mx+b)
15x-12y=60
15x-60-15y=0
15x-60=12y
12y=15x-60
divide both sides by 3
4y=5x-20
divide both sides by 4
y=5/4x-5
just put in values for x and get y so exg
(x,y)
0,-5
1,-15/4
2,-5/2
3,-5/4
4,0
and so on
Answer:
408
Step-by-step explanation:
because is you use long multiplication you will get 12*34=408.
The answer I’m pretty sure is 5 and if it’s not that it’s -5. It’s one of those let me know if it not and I’m sorry.
