All terms have an x in them, so you factor that out first to get
Now the 2nd degree equation will be of the form (3x- ... y)(x- ... y) and by just trying you find that the ... is just 1. So the factorization is:
Answer:
<em>$284</em>
Step-by-step explanation:
First,<em> find 1/3 of 426 by multiplying 1/3*426</em>
With your answer <em>(142)</em>, subtract that from the total in your checking account.
<em>426-142=284</em>
This means, After withdrawing the amount she will use to pay bills, Her left over total will be <em>284 dollars.</em>
The two equations for the set up are:
x+y=23 where x is the number of dimes and y is the number of nickles
10x+5y=185
Now you solve by elimination and substitution.
Multiply your first equation by -5 and add the two equations together
-5x-5y=-115
+10x+5y=185
-------------------
5x=70
x=14
Substitute that into your original equation:
14+y=23
y=9
So you have 14 dimes and 9 nickles.

I think that's how u do it im not sure
F(x) = -9x^2 + 7x + 2
Factorising we get:
f(x) = (x + 1) (-9x + 2)
The solutions are x = -1 and 2/9ths
