Answer:
80
Step-by-step explanation:
in the figure above, angle 100 degrees is corresponding to the angle co - interior to angle x
that is
if we put an angle that is at the upper left of x, we can call that y which is corresponding to 100 degrees
since y is corresponding to 100 degrees, it automatically becomes the same as 100 degrees
therefore y=100
now, from the first line above, we know that x and y are co-interior which means that they both add up to 180 degrees
that is
x+y=180
we know that y = 100
therefore,
x+100=180
collect like terms and
x = 180-100
therefore,
x= 80
thank you!!
The
first graph.
The equation is x - 1

3
In order to solve it, you need to get x by itself.
Add 1 to both sides. 3+1=4
x

4
Since this is your sign

the arrow has to point towards the left, and the circle needs to be colored in.
Answer:
18
Step-by-step explanation:
Divide with by paratheses first. Use PEMDAS method
It’s (x-6)(x+4) so the first one and last one
