Hello! remember you have to write complete questions in order to get good and exact answers. Here I'll explain this in a general way assuming the following table:
As you can see, x increases in steps of 1 units. So let's check the difference in y:
So we have a constant difference and we can conclude the table represents a line. Since the line passes through then y is directly proportional to x, so we can write:
Then:
Finally, the equation of the line is:
Answer:
+8
Step-by-step explanation:
They gained 8 yards so it is +8.
Answer:
-14 or 13
Step-by-step explanation:
x + x^2 = 182
x^2 + x - 182 = 0
rearrange and solve by completing the square
x^2 + x = 182
x^2 + x + 1/4 = 182.25
(x + 1/2)(x + 1/2) = 182.25
(x + 1/2)^2 = 182.25
x + 1/2 = root 182.25
x = + or - root 182.25 - 0.5
x = + or - 13.5 - 0.5
x = 13 or x = - 14
Answer:
Explanation:
[ Divide Both Sides By 12y ]
12xy / 12y = 5z / 12y
- PNW
if two opposite sides are 4cm each then their total length is 8cm. If the total length is 24cm then to work out the possible lengths of the other two sides you subtract 8 from 24 which gives you 16. A rule in rectangles is that opposite sides are equal so each remaining side would have a length of 16/2 which is 8. To get all the possible answers you have to go through all the possible perimeters (assuming all perimeters have to be whole numbers) between 24(max) and 9(min) and do those steps.
