Answer: No, it is not a solution
==========================================================
Explanation:
The point (3,-4) means that x = 3 and y = -4 pair up together
Let's plug these x,y values into each equation
Starting with the first equation, we get,
y = 4x-16
-4 = 4(3)-16 ... x replaced with 3; y replaced with -4
-4 = 12-16
-4 = -4 .... this is a true statement
Repeat for the second equation
y = 2x-6
-4 = 2(3)-6
-4 = 6-6
-4 = 0 ... this is false
Since we get a false statement, this means (3,-4) is not on the line y = 2x-6, which means that overall (3,-4) is not a solution to the system of equations. The point (3,-4) must make both equations true for it to be a solution.
Answer:
All real numbers except x=-7
Step-by-step explanation:
Since 
is a discontinuity in the rational function, this makes the denominator equal to 0.
Answer:
y+8 = 1/5(x+4)
Step-by-step explanation:
The point slope form of a line is
y-y1 = m(x-x1) where m is the slope and (x1,y1) is a point on the line
y- -8 = 1/5(x - -4)
y+8 = 1/5(x+4)
The correct answer is y=6x^(2)-1
Multiple 'm' in y=mx+b By 8
8(3/4)= 24/4= 6
