Answer:
Step-by-step explanation:
I will ASSUME you mean
-41 = (-2/5)(45n + 60) + n
and not -41 = -2/(5(45n + 60)) + n
or -41 = -2/(5(45n + 60) + n)
-41 = (-2/5)(45n + 60) + n
distribute the (-2/5)
-41 = -18n - 24 + n
combine like terms
17n = 17
reduce to simplest form
n = 1
Answer:
9x=18
Divide by 9
X=2
Step-by-step explanation:
If your quadratic function has x intercepts of 4 and -3, that means that the points are (4, 0) and (-3,0), or the values x has when y=0. Since your quadratic (which represents y) must then equal 0, then your factors of that equation would potentially equal 0 as well. That means that if x=4, then subtract 4 from each side to get x-4=0, and so one factor is (x-4) Similarly your other factor would be (x+3).
<span>To get your quadratic, FOIL: </span>
<span>(x-4)(x+3)=0 </span>
<span>x^2-x-12=0</span>
Answer:
6/2=3
3*10=30
10*3.14=31.4
30+31.4=61.4 or rounded to 61
