Answer:
y=-4 is the y=mx+B format
If the perimeter is 30
and the length is twice the width
c=length
w=width
2c=w
a pool table has 4 sides, the two adjacent sides will be equal so we only need to account for 1 of the widths and 1 of the lengths
meaning we only need to use half of the perimeter, or 15
if the length is twice as long as the width
the length would be 10
the width would be 5
there are two widths and 2 heights so the perimeter would correctly add up to 30 feet, proving you have the right answer
The altitude might be another name for a height of a pyramid, lol, hope this helps
Answer:
-4 =x
Step-by-step explanation:
2x - 5= 5x + 7
Subtract 2x from each side
2x-2x - 5= 5x-2x + 7
-5 = 3x+7
Subtract 7 from each side
-5-7 = 3x+7-7
-12 = 3x
Divide by 3
-12/3 = 3x/3
-4 =x
Answer:
x > 29
Step-by-step explanation:
to solve this inequality we would say
-x < -29
-x = - 29
divide both side by the - ( negative sign)
-x/- = -29/-
x = 29
therefore x > 29
