Hello!

Slope-intercept form is y = mx + b where:
m = slope
b = y-intercept
Plug in the given values:
y = 2x - 4
Answer:
The expression 7x represents the height of the container.
Step-by-step explanation:
From the question:
We are being informed that; if the length of the container is half of a foot longer than its width.
Let the width be x;
Then the length of the container can now be ; x+1/2
We all known that the volume of a rectangular prism is : V= l×w×h
here;
l = length
w = width
h = height
If we rewrite the given expression :
;
Then we factor we make a similar coefficient of the above equation, the remaining entities left in the parenthesis should be a linear term with a leading coefficient of 1 to match the expression for the length of the container.
i.e

Hence, if the length of the container is half a foot longer than its width, x, then the expression 7x represents the height of the container.
26/100 or simplified to 13/50
Is this the full question that is stated?
Answer:
add 17.50 to 8.75 you get 26.25
