Step-by-step explanation:
A(2,5) that is the answer / coordinates
For this case we have the following functions:
We must find . By definition we have to:
So:
We add similar terms:
Answer:
Option D
Answer:
14 and 10
Step-by-step explanation:
We have the equation x(x-4)=140. We can distribute the x to everything in the parenthesis so it's easier to work with.
x(x-4)=140
Let's move 140 to the left side, so we can solve this equation better by finding the zeros of the equation.
To find the zero, we have to find TWO values that multiply to -140 but add to -4.
(x-14)(x-10)=0
To find the zeros. make both of those parenthesis equal to zero.
x=14, 10
Answer:
x=-5/4 or x=9/4
Step-by-step explanation:
2 - 4x = -7
-4x = -7 - 2
-4x = -9
x = 9/4
or
2 - 4x = 7
-4x = 7-2
-4x = 5
x = -5/4
