The slope is negative as it slopes to the left
using the extremities of the line:-
-(10+10 / (10 + 10) = -1
slope is -1.
14. 7+3=10 and 7-3=4 so 7x2=14
Answer:
Step-by-step explanation:
The absolute value of a number is how far away it is from 0 on the number line. Even though 
is a negative number, the absolute value wouldn't be , because distance can't be negative. Hence the absolute value of is .
So, x^2 + 14 x + 49 - 4 = 0;
Then, we use the formula ( a + b )^2 = a^2 + 2ab + b^2;
We have ( x + 7 )^2 - 2^2 = 0;
Then, ( x + 7 )^2 - 2^2 = 0;
We use the formula a^2 - b^2 = ( a - b)( a + b );
We obtain ( x + 5 )( x + 9) = 0;
Then, x + 5 = 0;
x = -5;
x + 9 = 0;
x = - 9;
-5 and - 9 are the zeros of the quadratic function.
