Answer:
b=3in
Step-by-step explanation:
SO first of all, the formula for area is lxw (length x width)
And our question tells us that
l x w=24in^2
4 x w = 24 (question tells us that length is 4 inches as listed on side)
4 x (b+3) = 24 (b+3 is the total width of the postcard)
4b + 12 =24 (multiply by 4 inside the bracket)
4b=12 (subtract 12 from both sides)
b=3 (solve for b by dividing by 4)

Hello there!
8 pound bag = $14.08
1 ounce = x
8x = 14.08
x = 14.08/8
x = 1.76
Thus, the price per ounce is $1.76
To double check if your answer is right or not, just multiply $1.76 by 8 and you'll see it equals to $14.08

Answer:
y - 3 = -2(x + 4)
Step-by-step explanation:
First, we must find the slope of the line by using the two points.
The slope of a line that is perpendicular to another is the negative reciprocal of the other line's slope. So the slope of the line perpendicular to the given line is -2. Now we must write the equation in point-slope form:
the slopes of these lines are equal when the determinant of the coefficient matrix is zero. Thus, for homogeneous systems we have the following result: A nxn homogeneous system of linear equations has a unique solution (the trivial solution) if and only if its determinant is non-zero.
