Step-by-step explanation:
Point slope form: (y−y1) = m (x−x1), where (x1,y1) is the point, and m is the slope.
(y- (-4)) = (5/6)*(x - 8)
(y + 4) = (5/6)*(x - 8)
If you want in standard form
(y + 4) = (5/6)*x - (5/6)*8
y = (5/6) x - (5/6)*8 - 4
y = (5/6)x - (16/6)
Answer:
(y + 4) = (5/6)*(x - 8)
Answer:
maximum blanket size is;
21cm x 19cm
Step-by-step explanation:
Perimeter of the rectangle is;
P = 2W + 2L
Miriam has an 80cm length of lace that she wants to add to the sides of her rectangular blue blanket.
Thus;
2W + 2L = 80
Divide both sides by 2 to get;
W + L = 40
We want to find the maximum size of the blanket which is the 2 values that will give the maximum area.
Possible measurement include;
- 21cm x 19cm
- 22 cm x 18 cm
- 23 cm x 17 cm
- 24 cm x 16 cm
Looking at them all, the one with the largest area is 21cm x 19cm
Thus, maximum blanket size is;
21cm x 19cm
I believe that the answer is 20. I am not entirely sure though.
31.415 to the nearest unit
After the 31, the next digit 4 is not up to 5 so we round down .
31.415 ≈ 31 to the nearest unit.
