Answer:
6x² + 5x - 2 = 0
Step-by-step explanation:
Given
2x² - 5x - 6 = 0 ← in standard form
with a = 2, b = - 5, c = - 6, then
sum of roots α + β = -
= 
product of roots =
= - 3, then
sum of new roots =
+ 
= 
=
= - 
product of new roots =
× 
=
= - 
Hence the required equation is
x² +
x -
= 0 or
6x² + 5x - 2 = 0 ( multiplying through by 6 )
I believe the answer is either 40 or 250.
The answer is 1561 yuans and 27 jiao.
Let f(x) = y.
y = 4x - 12
Let x = 0
y = 4(0) - 12
y = - 12
This leads to the point (0, -12).
Let y = 0.
0 = 4x - 12
1 2 = 4x
12/4 = x
3 = x
This leads to the point (3, 0).
We now graph both points and then connect each point with a straight line.
