Answer:
tep-by-step explanation:
In order to find the integral:
we can do the following substitution:
Let's call
Then
which allows us to do convert the original integral into a much simpler one of easy solution:
Therefore, our integral written in terms of "x" would be:
We need an equation for this, theres no 'formula' for doing this (ignoring the quadratic formula, as that is a long-winded way of factorising a quadratic equation)
Answer:
You can solve this by substitution method
substitute the value of Y from 2nd equation in the first thet will give you the value of X and once your find the value of X you can substitute that value in any of the equation and get the answer
Answer:
A. y = -2x - 3
Step-by-step explanation:
y-5= -2(x + 4)
Expand the brackets.
y - 5 = -2x - 8
Add 5 to both sides.
y = -2x - 8 + 5
y = -2x - 3
