Step 1 = Write the equation in standard form 7x^2-6x+7= 0
Step 2 = Substitute the value of a,b,c into the quadratic formula
Step 3 = Simplify the discriminant
The solution is not a real number
Answer:
100.8
Step-by-step explanation:
Answer:
A.
Step-by-step explanation:
4y = 12x + 16
3x = y - 4
=>
y = 3x + 4
using that in the first equation
4(3x+4) = 12x + 16
12x + 16 = 12x + 16
=> both lines/equations are identical, so they have infinitely many solutions.
