Answer:
y = 1/7x + 88/7
Step-by-step explanation:
y = mx +b
since it is perpendicular you have to get the negative reciprocal of the slope which is 1/7
y = 1/7x + b then you would plug in your points
12 = 1/7(-4) + b and then solve for b
12 = -4/7 + b
+ 4/7
88/7 = b
y = 1/7x + 88/7
Volume = Length x Width x Height
Volume = 80 x 45 x 12
Volume = 43200 ft³
Cost per cubic foot = $625 000 ÷ 43200
Cost per cubic foot = $14.47

Answer: $14.47 per cubic foot.

Answer:
There are many examples the basics are also easy to remember.
Step-by-step explanation:
We can input these for the following equation.
x > 5
(x is greater than 5)
Then compare to - x < 5
(minus x is less than 5)
We try a sum
3x -2 ≤ 1
we can then balance subtract -2
3x ≤ -1
then divide by 3
x= -1 /3
We try another value
3x -2 ≤ 0
1 ≤ 3x
1/3 ≥ x
We can check that each equality fits and alter the number accordingly.
For the first one we are saying it is no greater than 1
For the second we say it is greater than zero.
We are able to prove both have the answer.
Just like when we look for negative percentages and count down we record this as we count in mental math.
Nine thousand, two hundred
