A graph of this inequality would be a number line, with the number -2 circled (not filled in), and the number line to the right of -2 shaded.
To solve this, you will combine like terms first:
-3x-7x < 20
-10x < 20
Divide both sides by -10:
-10x/-10 < 20/-10
When you divide an inequality by a negative number, you flip the inequality symbol:
x > -2
Answer:
Step-by-step explanation:
<UWV = 180° - 50° - 50° ( SUM OF ANGLE IN A TRIANGLE)
<UWV = 80° which is angle A
b = 20 ( isosceles triangle)
Answer:
(3,7), (3,8), (3,9), (3,10) is not a function.
Step-by-step explanation:
A function is defined as a relation in which each input value has only a single output value.
This means that for each 
value there should be only one 
value. If this criteria is not fulfilled then the relation cannot be called a function.
For the given set of points, we notice that for 
, 
which shows there are many y-values o for a single x-value. This means there are many outputs for a single input. This disqualifies it to be a function.
Thus, (3,7), (3,8), (3,9), (3,10) is not a function.
Answer:
5 pi/12
Step-by-step explanation:
To change degrees to radians, multiply by pi/180
75* pi/180
divide the top and bottom by 15
5 pi/12
