P(x) = 2x² - 4xq(x) = x - 3
To find the answer, we plug q(x) into p(x):
p(q(x)) = 2(x - 3)² - 4(x - 3)p(q(x)) = 2(x² - 6x + 9) - 4x + 12p(q(x)) = 2x² - 12x + 18 - 4x + 12p(q(x)) = 2x² - 16x + 30
The third option is correct.
Pretend the greater than less sign is an equal sign
9y - 4y > -7 -3
5y > -10
When you divide both sides by a negative, the sign flips but here the sign doesn’t flip because we don’t need to divid by a negative
y>-2
Answer:
180-(40+50)=90
Step-by-step explanation:
y = 90 degrees
The solution of a linear inequality in two variables like Ax + By > C is an ordered pair (x, y) that produces a true statement when the values of x and y are substituted into the inequality.
Example
Is (1, 2) a solution to the inequality
2x+3y>1
2⋅1+3⋅2>?1
2+5>?1
7>1
The graph of an inequality in two variables is the set of points that represents all solutions to the inequality. A linear inequality divides the coordinate plane into two halves by a boundary line where one half represents the solutions of the inequality. The boundary line is dashed for > and < and solid for ≤ and ≥. The half-plane that is a solution to the inequality is usually shaded.
Example
Graph the inequality
y≥−x+1

Answer:
12 >or equal 3.50 + 2.75 + x
X is what you have left over
x > or equal to 5.75
Step-by-step explanation:
Solve for X.
Don't let the >or equal sign intimidate you.
Treat it like and equal sign but don't replace it.
What you do on the right you must do on the left.
