Answer:
-1800
Step-by-step explanation:
18=9000
23=7200
18-23=7200-9000=-1800
Answer:
y=1/34x+48/17
Step-by-step explanation:
Perpendicular means negative reciprocal of the slope.
y-y1=m(x-x1)
y-3=1/34(x-6)
y-3=1/34x-6/34
y=1/34x-6/34+3
y=1/34x-6/34+102/34
y=1/34x+96/34
y=1/34x+48/17
Answer:
6. The set of non-positive integers includes 0 while the negative integers do not.
7. 3 x π does not give a rational number, but another irrational which is 3π.
8. Addition and Multiplication
9. 9-(8-7) which is 8 is not equal to (9-8)-7 which is -6.
10. Zero. Any number added to zero is equal to the number itself.
11. 1/x.
A triangle always equal 180.
The two marks indicate that 3x and the unlabeled corner is congruent to each other.
Let the unlabeled corned be another x.
Add everything and equal it to 180.
3x+x+x=180
Combine like terms.
5x=180
Divide by 5.
x=36
Substitute the x in 3x for 36.
3(36)=108
Then subtract that number from 180.
180-108=72
Divide the 72 by 2 so it can come out evenly. That’s 36.
Thus
3x=108
x=36
Unlabeled=36
Hope this helps.
It's 50 because 3 is half of 6
