Answer:
x=0.875
Step-by-step explanation:
2×+y=1
y=0.5
4×+2y=-1
4×+2.5=-1
1+2.5=4x
3.5=4x
x=0.875

Answer: x = 35</h3>
==========================================================
Explanation:
All three angles must add to 180. This is true for any triangle.
x+x+110 = 180
2x+110 = 180
2x = 180-110 ... subtract 110 from both sides
2x = 70
x = 70/2 .... divide both sides by 2
x = 35
As a check: 35+35+110 = 180 which helps confirm the answer.
Answer:
Step-by-step explanation:
Answer:
"absolute value function," y = |x|
Step-by-step explanation:
This is the graph of the "absolute value function," y = |x|.
For the first digit there are 7 choices. For the second digit there are 6 choices (because we can't use the same one again). And so on, until there is only one choice for the last digit.
The number of possible codes is this:
7*6*5*4*3*2*1 = 7! = 5040
