Answer:
Step-by-step explanation:
The difference quotient in general looks like
Sometimes the symbol "delta x" 
is used instead of h.
For the exponential function, the difference quotient is
Substitute the x with 5
-(5)2 + 4(5) - 10 = 0
Answer:
Step-by-step explanation:
Let as us 45 as the number we should use to get the square root in the simplest form
And then 144
The square root of a number in is simplest form means to get the number inside the radical as low as possible
Answer:
x = all real numbers
Step-by-step explanation:
first you need to solve the first equation to figure out what y is.
4x - y = 2
<em>add y to both sides of the equation</em>
4x = 2 + y
s<em>ubtract 2 from both sides of the equation</em>
4x - 2 = y
now that you know what y is, you can substitute it in the next equation.
3y = 12x - 6
3(4x - 2) = 12x - 6
<em>open the parenthesis </em>
12x - 6 = 12x - 6
<em>subtract 12x from both sides of the equation</em>
-6 = -6
regardless of what x is, -6 will always equal -6.
so, the answer is all real numbers.
