Answer:
80
Step-by-step explanation:
180-(60+40)=180-60-40=180-100=80
Answer:
slope = 1
Step-by-step explanation:
-3 | -3
5 | 5
_____
8 | 8
8/8= 1
Answer:
The endpoint coordinates are (3,12)
Step-by-step explanation:
You multiply 4 by 2 which gives you 8 and write the equation
then you subtract 5 from 8 to get 3 for the x coordinate.
You multiply 3 by 2 which gives 6 and writhe the equation
then you substitute the -6 for +6 and add +6 and 6 to get 12 for the y coordinate.
To check use the midpoint formula with coordinates D and your endpoint coordinates
and you get the answer for the midpoint which is (4,3)
Answer:
-16
Step-by-step explanation:
(-3 + (-5))(-3 - (-5))
(-3 - 5)(-3 + 5)
(-8)*2
<u>-16</u>
Lines AB and AC are equal so you set up an equation like so...
4x + 1 = 2x + 23
Subtract 1 from both sides.
4x = 2x + 22
Subtract 2x from both sides.
2x = 22
Divide.
x = 11
Now you need to plug in 11 into 3x - 8.
3(11) - 8
= 33 - 8
= 25
So BC is 25.
I hope this helps love! :)
