Answer:
540°
Step-by-step explanation:
Formula: note that n means nr of sides
(n-2)×180°
(5-2)×180°=3×180=540°
Where each angle are 540°÷5=108°
Answer: B. |x-100| = 25
Explanation:
Draw out a number line. Mark 75, 100 and 125 on the number line as points A, B, and C in that order. Don't worry about the spacing.
The value of x represents where the train is. So if we had say x = 85, then it would be at location 85 on the number line. Writing |x-100| is the distance from x to 100. The absolute value ensures the distance is never negative. We want this distance to be 25 because after traveling 25 cm, the switch is turned, and the train goes the other way.
Since 88 has no decimal, you would but a zero behind it and then subtract. You have to borrow from the 8 (make it a 7) and make zero 10. Then subtract. 10-7=3, 7-3=4, 8-4=4. Your answer will be 44.3
Answer:
Hello!!! Princess Sakura here ^^
Step-by-step explanation:
When you want to find out what the slope is, you have to remember what the formula is first....
so in this case -3 would be the 
because it's the y in the ordered pair and it's the second one. Then one of the 5's would be 
and 9 would be 
and then the other 5 would be 
.
now if we plug it in
now we can tell that we can't divide by zero so the slope would be unidentified and that's it.
Answer is D the last one
if the equation is y= 3 lx + 2l
if you solve for x then the zero is x= -2
if y intercept .. so x = 0
then point is (0,6)
hope that helps
