x-intercept is 6, coordinates (6,0)
y-intercept -4, coordinates (0,-4)
gradient= y1-y2/x1-x2= 0-(-4)/6-0= 4/6= 2/3 or 0.667 (3.s.f.)
First do distrubutive property
-(x+4)=-8
Multiply the parenthesis by the invisible -1 in the front
: -x-4=-8
Now add 4 to both sides
-x=-4
then divide -1 by both sides
x=4 is your answer
Answer:

Add each sides' centimeters together to get the perimeter. multiply length x width to get the area. I hope this helped
Answer:
Step-by-step explanation:
Let Carl do the job in c days, Anne- in a, and Bob in b days
Then the portion of job they can do is 1/c, 1/a and 1/b
<u>As per given we have below equations:</u>
- 1/c + 1/b= 1/6
- 1/a + 1/b = 1/3
- 1/a + 1/c = 1/5
<u>Sum of all 3 equations gives us:</u>
- 2(1/a + 1/b + 1/c) = 1/6 + 1/3 + 1/5
- 2(1/a + 1/b + 1/c) = 5/30 + 10/30 + 6/30
- 2(1/a + 1/b + 1/c) = 21/30
- 2(1/a + 1/b + 1/c) = 7/10
- 1/a + 1/b + 1/c = 7/20
It means all three together can complete 7/20 of the job in one day
<u>The rest of the job is done by Anne and Bob:</u>
<u>As Anne and Bob can do 1/3 of the job in one day, they need time to complete the rest:</u>
<u>Add 1 day to this to find overall time:</u>
- 1 + 39 /20 = 59/20 days or 2.95 days
