What does it mean if the x-coordinate in an ordered pair is zero? What if the y-coordinate is zero? Both? Explain.
1 answer:
If the x-axis ordered pair is (0,0) and the y-axis ordered pair is (0,0), it is just where the lines intersect or also known as the origin. Both x and y can have a (0) in it.
for example let's say that you have an ordered pair on the X-axis of (5,0) and a ordered pair on the y-axis of (-3,0) it would look like that^^
or if it was just (0,0) it would be a dot in the middle
Don't know if it helped much, but there ya go

Answer:
a=35 given
b=40
c=110
I couldn't complete see c. Please look at the picture to see what I assumed it to be.
Step-by-step explanation:
Hmmm... I guess a and b are not vertical.
We are given b=180-4a and a=35 so b=180-4(35)=180-140=40.
So b=40.
Isosceles triangles always have congruent base angles. So let's call both of the base angles in the bottom triangle x.
That means x+x+40=180.
We need to solve this for x.
Combine like terms:
2x+40=180
Subtract 40 on both sides:
2x=140
Divide both sides by 2:
x=140/2
Simplify:
x=70
So I'm assuming that c and it's adjacent angle are sitting on a straightedge together which means 70+c=180.
70+c=180
Subtract 70 on both sides:
c=180-70
Simplify:
c=110
