For number 3 it would be |-10| and |10|.
Number 5a is supposed to <, because -1 is greater than -7 when you look at the line graph. The same goes for 5b. 5d is >, because 0 is always greater than -1 and it shows that on the line graph that you have there. 5e is =.
I don't see anything else wrong though. Just the ones I listed.
Hope that helps!
Answer:
2)105°
Step-by-step explanation:
In this parallelogram, J should be congruent to L (J=L). We can solve this problem if we find out the value of L.
The sum of the adjacent angle of the parallelogram will be equal to 180 degrees, so the equation is
L + M = 180
M=180- L
If L exceeds M by 30 degrees then the equation will be
L=M +30
If you combine both equations, it will be
L+30 = M +30
L+30 = (180- L) +30
L + L= 180 + 30
2L= 210
L=105
The first two pairs.. just substitute the x-coordinate and find y
200 - (2x) = 42
200 - 42 = 2x
158/2 = 2x/2
x = 79

We have

So

The rational term vanishes as <em>x</em> gets arbitrarily large, so we can ignore that term, leaving us with

and this happens if <em>a</em> = 1 and <em>b</em> = -1.
To confirm, we have

as required.
