Question 5 is (1,0)
These are are definitely correct
Answer:
B
Step-by-step explanation:
To solve -6-(-4) you need to break it down.
First, multiply -(-4) which would equal 4 (negative times negative equals positive)
Then add 4 to -6 (-6+4)
This equation is being expressed through option B
Hope this helps! :)
If you are solving for h the answer is 10
First you reduce the fraction with 8 so your get
4=40/h
Then you multiply both sides by h and you get
4h=40
After that you divide both sides by 4
And your answer is
h=10

Step-by-step explanation:
When there's a letter, it represents a variable. You need to find the value (number) of this variable. This can be done by trying to isolate (put it by itself) the variable. So now, here is how to do it:
1) -2j + 6 = 2j - 8
-2j - 2j = - 8 - 6
-4j/4 = -14/4
j = 14/4
j = 7/2
2) 4h + 6 = 2h - 8
4h - 2h = - 8 - 6
2h/2 = - 14/2
h = -7
3) 9w + 9 = 3w - 15
9w - 3w = - 15 - 9
6w/6 = -24/6
w = -4
4) 45 = -9(e + 8)
45 = -9e - 72
45 + 72 = -9e
117/-9 = e
e = -13
5) 35 = -7t
35/-7 = t
t = -5
6) 12k + 13 = 8k + 33
12k - 8k = 33 - 13
4k/4 = 20/4
k = 5
