Answer:
y = 3/4x + 2
Step-by-step explanation:
y = mx + c is the formula to find the equation
to find a equation we should have a point and a gradient ( m )
now, point = (4 , 5) m = 3/4
then we sub the point and the gradient (m) into the equation formula
y=mx + c
5 = 3/4 (4) + c
5 = 3 + c
5 - 3 = c
2 = c
c = 2
now we rewrite the equation become y= 3/4x + 2
Answer:
C. 18/24 and 6/12 is proportional
Answer:
The price is $1.6 per square foot of the land
Step-by-step explanation:
step 1
Find the area of the plot of land
we know that
The area of the plot of land is equal to the area of trapezoid 1 plus the area of trapezoid 2
see the attached figure to better understand the problem
Remember that
The area of a trapezoid is equal to
<em>Find the area of trapezoid 1</em>
we have
substitute
<em>Find the area of trapezoid 2</em>
we have
substitute
The area total of the land is
step 2
Find the price per square foot of the land
Divide the total cost by the total area
Answer:
The lower the volume, the higher the pressure.
Step-by-step explanation:
Volume and pressure are inverse to each other -- so the more pressure, the less volume, and vice versa. Think of it like this: if you were squished into a tiny room, there would be a lot of pressure on you, and not a lot of volume to move in!
You can also think of it numerically. The higher the V in that equation (the higher the denominator) the lower the p in the equation.
