Answer:
a)
b) a=28 ; b=-16
Step-by-step explanation:
*For b only:
We know that
From this we create an equation
We solve the equation
Answer:
x=2/3+1/3
Step-by-step explanation:
Let's solve your equation step-by-step.
3x2−4x−2=0
For this equation: a=3, b=-4, c=-2
3x2+−4x+−2=0
Step 1: Use quadratic formula with a=3, b=-4, c=-2.
Answer:
No Solution
Step-by-step explanation:
<u>For one solution;</u>
it will be consistent and independent ( example, x = 1 and y = 2)
<u>For no solution;</u>
it will be inconsistent and independent ( example, 0 = 2)
<u>For many solution;</u>
it will be consistent and dependent ( example, 1 = 1, 2 = 2, y = y, x = x)
Given;
3x - 2y = 3 -------------- equation (1)
6x - 4y = 1 --------------- equation (2)
6: 18x - 12y = 18 -------------equation (3)
3: 18x - 12y = 3 --------------- equation (4), <em> subtract (4) from (3)</em>
--------------------------------------------
0 - 0 = 15
-----------------------------------------------
0 = 15
The solution is inconsistent and independent, because zero (0) cannot be equal to 15
Thus, the system has no solution
Yo sup??
The solution of the system of equations would be the points where the two graph intersects
This happens at two places
Therefore the solution set is
{(2,2),(-1,4)}
The right answer is option 4
Hope this helps.
I only know the answer to number 4 and I believe that it is C
