Step-by-step explanation:
A root is a value for which a given function equals zero. When that function is plotted on a graph, the roots are points where the function crosses the x-axis. For a function, f(x) , the roots are the values of x for which f(x)=0 f ( x ) = 0 .
Answer:
x = 3
Step-by-step explanation:
4x + 3 = 5x
4x = 5x - 3
4x - 5x = -3
(4 - 5)x = 1x
-1x = -3
x = -1 × (-3)
<u>x</u><u> </u><u>=</u><u> </u><u>3</u>
Answer:x=2 and y=3
Step-by-step explanation:
Given that y=2x-1
Then, 3x+2y=12
3x+2(2x-1)=12
3x+4x-2=12
7x=14
x=2
y=2(2)-1
y=3
