I think the way that you do is 5/5+3=5/8
5/8*4=2.5 so 2.5 is the answer
Midpoint of (9,10) = 9.5 Midpoint of (-9,-10) = -9.5
Let's factor the following polynomial to find the roots:
x2-13x + q = 0
Factoring we have:
(x-12.5) * (x + a)
Where,
-12.5 + a = -13
a = -13 + 12.5
a = -0.5
We now look for the coefficient q:
q = -12.5 * a
q = -12.5 * (- 0.5)
q = 6.25
The polynomial will then be:
x2-13x + 6.25 = 0
Its roots are:
x1 = 12.5
x2 = 0.5
Answer:
The other root and the value of the coefficient are:
0.5 and 6.25 (Respectively)
Ok let's start with question 1.
1. The equation is given. If she advices 360 people each week for 4 week she earns...
4(80+360(15)/100) = $536
2. In this problem instead of evaluating M we solve for n with M given.
140=80+15n/100
n=400 people
3. The new equation will still follow the same format.
M=65+21n/100
4. This will be the intersection point of the two lines. So when does...
80+15n/10=65+21n/100
We just have to solve for n.
-0.06n=-15
n=250 people
