we know that
the area of the rectangular banner is equal to

where
W is the wide of the banner
h is the height of the banner
in this problem


In the formula of the area solve for h

Substitute the values of W and A

therefore
the answer is
the height of the banner is 
Answer:
(0, 8/3) = y-intercept
Step-by-step explanation:
I chose to find the y-intercept since it is easy to find with the given information.
The equation for a line is y = mx + b
To find the y-intercept, we must plug in the info we have and solve for b:
4 = -1/3 (-4) + b
4 = -4/3 + b
8/3 = b
To find a point on the line, you also could have added -1 to 4 and 3 to -4 since slope means rise/run or change in y/change in x:
(y - 1) / (x + 3) = (4 - 1) / (-4 + 3) = (3, -1) (flip since it's the y and x coordinate) = (-1, 3)
The exact
value of the given equation is 45 degrees or pi/4. I am hoping
that this answer has satisfied your query about and it will be able to help
you, and if you’d like, feel free to ask another question.
Y=2(-1)^2-6(-1)+3
y=2+6+3
y=8+3
y=11
