Answer:
(4, 3 )
Step-by-step explanation:
Given a system of equations graphically, then the solution is at the point of intersection of the 2 lines.
The lines intersect at (4, 3 ) ← solution
Answer:
the amount the stock changed over the day = $29
Step-by-step explanation:
The stock cost $122 at the start of the day . At the end of the day it cost $93. The amount the stock value changed can be calculated below.
The initial amount of the stock that days was $122 but at the end of the day it changes to $93. This means the stock cost decreases over the day.
Initial cost of stock at the day = $122
Final cost at the end of the day = $93
the amount the stock changes over the day = initial cost of stock at the day - final cost at the end of the day.
the amount the stock changes over the day = 122 - 93
the amount the stock changed over the day = $29
Generally, the stock decreased over the day.
Answer:
<em>The answer is 0</em>
<em>So I think no solutions</em>
Step-by-step explanation:
You gotta get each equation into slope-intercept form, nd when u do that 9x - 3y = 6 turns into y = 3x - 2, nd 5y = 15x + 10 turns into y = 3x + 2. Add the equations together, nd get 0.
The discriminant is b^2 -4ac
a = 1
b = -2
c = 4
discriminant = 4 -4 * 1 * 4 =
4 -16 =
-12
I get MINUS 12 as the answer but that isn't one of the choices.
