First, multiply. 7x-14-4x+9. Now, add the like terms. 3x-5.
Answer:
and 
Step-by-step explanation:
We must solve the quadratic equation to find the values of x that satisfy equality

Subtract 24 on both sides of equality


Now we factor the quadratic equation
Identify two numbers that when you add them you get as a result 2 and when you multiply them you get as a result -24
The numbers sought are: 6 and -4
So the factors are:

Finally note that the solutions are:
and

Answer:
The answer to your question is x-axis, y-axis
Step-by-step explanation:
To answer this question just remember the equation of the slope
m = 
Then:
If the numerator is zero, the line is parallel to the x-axis and the slope will be zero.
If the denominator is zero, the line is parallel to the y-axis and the slope will be undefined.
Answer: a = 4/3
Step-by-step explanation:
1. a/4 − 5/6= −1/2 convert -1/2 to -3/6
2. a/4 = 5/6 - 3/6 = 2/6 = 1/3
3. a = 4*2/6 = 4*1/3
4. a = 4/3
