Answer:
p>-3 open circle going to the right
closed circle going to the left
n<5 open circle going to the left
closed circle going to the right
1>x open circle going to the left
-1=d just a closed circle
Step-by-step explanation:
Before I answer these here are some good notes
If the inequality sign is < or > then the circle is going to be open
If the inequality sign is then the circle is going to be closed
If the inequality sign is facing the variable (ex: x>3) then the line is going to be going to the right
If the inequality sign is facing the constant (ex: x<3) then the line is going to be going to the left
p>-3 open circle going to the right
closed circle going to the left
n<5 open circle going to the left
closed circle going to the right
1>x open circle going to the left
-1=d just a closed circle
Sum of complementary angles always equal to 90°.
Given, <A and <J are complementary angles. So, we can set up an equation as following:
m<A+ M<J= 90
Next step is to plug in m<A = 5x + 30 and m<J = 4x +15 in the above equation. So we will get,
5x+30+4x+15=90
(5x+4x)+(30+15)=90 Group the like terms.
9x+45=90 Combine the like terms.
9x+45-45=90-45 Subtract 45 from each sides.
9x=45 By simplifying.
Divide each sides by 9.
x=5.
So, x=5.
