Answer:
-20
Step-by-step explanation:
multiply 5 and 6 then 5 and -10
30-50=-20
Answer:
Option A
Step-by-step explanation:
2x^2+10x+12
Divide through by 2
x^2 +5x+6=0
x^2 +3x+2x+6
x(x+3)+2(x+3)=0
(x+2)(x+3)=o
x=-2 or x=-3
A. Surveying the students about their favorite type of math problem.
and
C. Sampling water for contaminants
we have

The solution is the shaded area above the dotted line
we know that
If a point is a solution of the inequality, then the coordinates of the point must satisfy the inequality
We will verify all cases to determine the solution of the problem
<u>Case A)</u> Point 

Substitute the value of x and y in the inequality and verify

-------> is not true
therefore
the point
is not a solution of the inequality
<u>Case B)</u> Point 

Substitute the value of x and y in the inequality and verify

-------> is true
therefore
the point
is a solution of the inequality
<u>Case C)</u> Point 

Substitute the value of x and y in the inequality and verify

-------> is not true
therefore
the point
is not a solution of the inequality
<u>Case D)</u> Point 

Substitute the value of x and y in the inequality and verify

-------> is not true
therefore
the point
is not a solution of the inequality
therefore
<u>the answer is the Point B</u>
