The zeroes of the function will be equal to ( 7, -6 ).
<h3>
What is a quadratic equation?</h3>
It is a polynomial with a degree of 2 or the maximum power of the variable is 2 in quadratic equations. It has two solutions as its maximum power is 2.
Given function:-
As we can see that the quadratic equation in the factorized form is ( x - 7 ) ( x+ 6 ) so we will equate each factor to zero.
( x- 7 ) = 0
x = 7
( x+ 6 ) = 0
x = -6
Therefore zeroes of the function will be equal to ( 7, -6 ).

Answer:
Changing the signs and the operation: 16+−9
Step-by-step explanation:
A tool that my math teacher taught us is a poem to remember the sign "Same sign add 'em up, different sign subtract. Give the sign to bigger number then you'll be exact". I hope this helps!
Substitute y = 2x + 3 into y = -x - 9
2x + 3 = -x - 9
Solve for x in 2x + 3 = - - 9
x = -4
Substitute x = -4 into y = 2x + 3
y = -5
Therefore,
<u>x = -4</u>
<u>y = -5</u>
