5. y = -3 x - 8
6. y = - 1/2 x + 1
Sum of interior angles in a pentagon=540°
148+112+2x+2x+10+90=540
360+4x=540
4x=540-360
4x=180
x=180/4
x=45°
Answer:
5.05
Step-by-step explanation:
3.85+0.05+1.15
= $5.05
The unit price is $6.25 because $43.75 divided by 7 is $6.25
Relation t is a function because it has no repeating x values
the inverse of relation t is when u switch the x and y values.
ex. inverse of (0,-2) is (-2,0).
and yes, the inverse of relation t is also a function because there are no repeating x values.
